+**Bug Fixes:**
+- **OSS Storage:** Fixed `SQLITE_CANTOPEN` errors when running as a LaunchAgent, systemd service, or in containers where `process.cwd()` is read-only (e.g. `/`). Default `vector_store.db` location changed from `process.cwd()/vector_store.db` to `~/.mem0/vector_store.db`.
+- **OSS Storage:** Fixed `historyDbPath` config being silently ignored — config merging always overwrote it with defaults. Top-level `historyDbPath` is now correctly propagated into `historyStore.config` with proper precedence.
+- **OSS Storage:** Added `ensureSQLiteDirectory()` — parent directories for SQLite database files are now auto-created before opening, preventing `SQLITE_CANTOPEN` when using nested paths.
+
+**Improvements:**
+- **Migration:** Added deprecation warning when an existing `vector_store.db` is found at the old `process.cwd()` location, guiding users to move it or set `vectorStore.config.dbPath` explicitly.
+- **Config:** Limited default SQLite config spreading to only SQLite history providers, preventing config leaking into Supabase or other providers.

+- **Dependencies:** Minimum Node.js version for OSS sqlite features is now Node 20+ (due to `better-sqlite3` v12)
+
+**Bug Fixes:**
+- **OSS Storage:** Replaced `sqlite3` with `better-sqlite3` to fix native binding resolution failures under jiti-based loaders (e.g. OpenClaw plugin system). Fixes issues where the `bindings` module walked V8 stack frames with synthetic filenames, failing to locate the native `.node` addon.
+- **OSS Storage:** Fixed async init race condition in `SQLiteManager` — `init()` is now synchronous
+- **OSS Vector Store:** Migrated `MemoryVectorStore` from `sqlite3` to `better-sqlite3` with transactional batch inserts

+**Improvements:**
+- **Performance:** Cached prepared statements in `SQLiteManager` for faster history operations

 ## Setup and Configuration
 
+### Understanding `userId`
+
+The `userId` field is a **string you choose** to uniquely identify the user whose memories are being stored. It is **not** something you look up in the Mem0 dashboard — you define it yourself.
+
+Pick any stable, unique identifier for the user. Common choices:
+
+- Your application's internal user ID (e.g. `"user_123"`, `"alice@example.com"`)
+- A UUID (e.g. `"550e8400-e29b-41d4-a716-446655440000"`)
+- A simple username (e.g. `"alice"`)
+
+All memories are scoped to this `userId` — different values create separate memory namespaces. If you don't set it, it defaults to `"default"`, which means all users share the same memory space.
+
+<Tip>In a multi-user application, set `userId` dynamically per user (e.g. from your auth system) rather than hardcoding a single value.</Tip>

 ### delete_all() Method
 
-#### No Breaking Changes
+#### Breaking Change — Empty filter no longer silently deletes everything
+
+**Before:** calling `delete_all()` with no filters silently deleted **all memories in the project**.
+
+**After:**
+- No filters → raises a validation error (prevents accidental full-project wipe).
+- Concrete ID (e.g. `user_id="alice"`) → deletes memories for that entity (unchanged).
+- `"*"` for a filter → deletes all memories for that entity type across the project (new).
+- All four filters set to `"*"` → explicit full project wipe (new, requires opt-in on every parameter).
+
+This change replaces the silent full-project delete (triggered by an empty or missing filter) with a validation error, and introduces `"*"` wildcards as the intentional path for bulk deletion.
+
 ```python
-# Same signature in both versions
+# v0.x — no filter silently wiped all project memories
-def delete_all(
+m.delete_all()                      # DANGER: deleted everything

 All new parameters are optional and backward-compatible — existing configurations work without changes.
 
+### Per-agent memory isolation
+
+In multi-agent setups, each agent automatically gets its own memory namespace. Session keys following the pattern `agent:<agentId>:<uuid>` are parsed to derive isolated namespaces (`${userId}:agent:${agentId}`). Single-agent deployments are unaffected — plain session keys and `agent:main:*` keys resolve to the configured `userId`.
+
+**How it works:**
+
+- The agent's session key is inspected on every recall/capture cycle
+- If the key matches `agent:<name>:<uuid>`, memories are stored under `userId:agent:<name>`
+- Different agents never see each other's memories unless explicitly queried
+
+**Explicit cross-agent queries:**
+
+All memory tools (`memory_search`, `memory_store`, `memory_list`, `memory_forget`) accept an optional `agentId` parameter to query another agent's namespace:
+
+```
+memory_search({ query: "user's tech stack", agentId: "researcher" })
+```
+
+Resolution priority: explicit `agentId` > explicit `userId` > session-derived > configured default.
+
 ## Setup
 
 ```bash
 openclaw plugins install @mem0/openclaw-mem0
 ```
 
+### Understanding `userId`
+
+The `userId` field is a **string you choose** to uniquely identify the user whose memories are being stored. It is **not** something you look up in the Mem0 dashboard — you define it yourself.
+
+Pick any stable, unique identifier for the user. Common choices:
+
+- Your application's internal user ID (e.g. `"user_123"`, `"alice@example.com"`)
+- A UUID (e.g. `"550e8400-e29b-41d4-a716-446655440000"`)
+- A simple username (e.g. `"alice"`)
+
+All memories are scoped to this `userId` — different values create separate memory namespaces. If you don't set it, it defaults to `"default"`, which means all users share the same memory space.
+
+> **Tip:** In a multi-user application, set `userId` dynamically per user (e.g. from your auth system) rather than hardcoding a single value.

+  Integrate Mem0 Platform into AI applications for persistent memory, personalization, and semantic search.
+  Use this skill when the user mentions "mem0", "memory layer", "remember user preferences",
+  "persistent context", "personalization", or needs to add long-term memory to chatbots, agents,
+  or AI apps. Covers Python and TypeScript SDKs, framework integrations (LangChain, CrewAI,
+  Vercel AI SDK, OpenAI Agents SDK, Pipecat), and the full Platform API. Use even when the user
+  doesn't explicitly say "mem0" but describes needing conversation memory, user context retention,
+  or knowledge retrieval across sessions.

+metadata:
+  author: mem0ai
+  version: "1.0.0"
+  category: ai-memory
+  tags: "memory, personalization, ai, python, typescript, vector-search"
+compatibility: Requires Python 3.10+ or Node.js 18+, pip install mem0ai or npm install mem0ai, MEM0_API_KEY env var, and internet access to api.mem0.ai
+---
+
+# Mem0 Platform Integration
+
+Mem0 is a managed memory layer for AI applications. It stores, retrieves, and manages user memories via API — no infrastructure to deploy.
+
+## Step 1: Install and authenticate
+
+**Python:**
+```bash
+pip install mem0ai
+export MEM0_API_KEY="m0-your-api-key"
+```
+
+**TypeScript/JavaScript:**
+```bash
+npm install mem0ai
+export MEM0_API_KEY="m0-your-api-key"
+```
+
+Get an API key at: https://app.mem0.ai/dashboard/api-keys
+
+## Step 2: Initialize the client
+
+**Python:**
+```python
+from mem0 import MemoryClient
+client = MemoryClient(api_key="m0-xxx")
+```
+
+**TypeScript:**
+```typescript
+import MemoryClient from 'mem0ai';
+const client = new MemoryClient({ apiKey: 'm0-xxx' });
+```
+
+For async Python, use `AsyncMemoryClient`.
+
+## Step 3: Core operations
+
+Every Mem0 integration follows the same pattern: **retrieve → generate → store**.
+
+### Add memories
+```python
+messages = [
+    {"role": "user", "content": "I'm a vegetarian and allergic to nuts."},
+    {"role": "assistant", "content": "Got it! I'll remember that."}
+]
+client.add(messages, user_id="alice")
+```
+
+### Search memories
+```python
+results = client.search("dietary preferences", user_id="alice")
+for mem in results.get("results", []):
+    print(mem["memory"])
+```
+
+### Get all memories
+```python
+all_memories = client.get_all(user_id="alice")
+```
+
+### Update a memory
+```python
+client.update("memory-uuid", text="Updated: vegetarian, nut allergy, prefers organic")
+```
+
+### Delete a memory
+```python
+client.delete("memory-uuid")
+client.delete_all(user_id="alice")  # delete all for a user
+```
+
+## Common integration pattern
+
+```python
+from mem0 import MemoryClient
+from openai import OpenAI
+
+mem0 = MemoryClient()
+openai = OpenAI()
+
+def chat(user_input: str, user_id: str) -> str:
+    # 1. Retrieve relevant memories
+    memories = mem0.search(user_input, user_id=user_id)
+    context = "\n".join([m["memory"] for m in memories.get("results", [])])
+
+    # 2. Generate response with memory context
+    response = openai.chat.completions.create(
+        model="gpt-4.1-nano-2025-04-14",
+        messages=[
+            {"role": "system", "content": f"User context:\n{context}"},
+            {"role": "user", "content": user_input},
+        ]
+    )
+    reply = response.choices[0].message.content
+
+    # 3. Store interaction for future context
+    mem0.add(
+        [{"role": "user", "content": user_input}, {"role": "assistant", "content": reply}],
+        user_id=user_id
+    )
+    return reply
+```
+
+## Common edge cases
+
+- **Search returns empty:** Memories process asynchronously. Wait 2-3s after `add()` before searching. Also verify `user_id` matches exactly (case-sensitive).
+- **AND filter with user_id + agent_id returns empty:** Entities are stored separately. Use `OR` instead, or query separately.
+- **Duplicate memories:** Don't mix `infer=True` (default) and `infer=False` for the same data. Stick to one mode.
+- **Wrong import:** Always use `from mem0 import MemoryClient` (or `AsyncMemoryClient` for async). Do not use `from mem0 import Memory`.
+- **Immutable memories:** Cannot be updated or deleted once created. Use `client.history(memory_id)` to track changes over time.

+# Mem0 Platform API Reference
+
+REST API endpoints for the Mem0 Platform. Base URL: `https://api.mem0.ai`
+
+All endpoints require: `Authorization: Token <MEM0_API_KEY>`
+
+## Endpoints
+
+| Operation | Method | URL |
+|-----------|--------|-----|
+| Add Memories | `POST` | `/v1/memories/` |
+| Search Memories | `POST` | `/v2/memories/search/` |
+| Get All Memories | `POST` | `/v2/memories/` |
+| Get Single Memory | `GET` | `/v1/memories/{memory_id}/` |
+| Update Memory | `PUT` | `/v1/memories/{memory_id}/` |
+| Delete Memory | `DELETE` | `/v1/memories/{memory_id}/` |
+
+## Memory Object Structure
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `id` | string (UUID) | Unique memory identifier |
+| `memory` | string | Text content of the memory |
+| `user_id` | string | Associated user |
+| `agent_id` | string (nullable) | Agent identifier |
+| `app_id` | string (nullable) | Application identifier |
+| `run_id` | string (nullable) | Run/session identifier |
+| `metadata` | object | Custom key-value pairs |
+| `categories` | array of strings | Auto-assigned category tags |
+| `immutable` | boolean | If true, prevents modification |
+| `expiration_date` | datetime (nullable) | Auto-expiry date |
+| `hash` | string | Content hash |
+| `created_at` | datetime | Creation timestamp |
+| `updated_at` | datetime | Last modification timestamp |
+
+Search results additionally include `score` (relevance metric).
+
+## Scoping Identifiers
+
+Memories can be scoped to different levels:
+
+| Scope | Parameter | Use Case |
+|-------|-----------|----------|
+| User | `user_id` | Per-user memory isolation |
+| Agent | `agent_id` | Per-agent memory partitioning |
+| Application | `app_id` | Cross-agent app-level memory |
+| Run/Session | `run_id` | Session-scoped temporary memory |
+
+**Critical:** Combining `user_id` and `agent_id` in a single AND filter yields empty results. Entities are stored separately. Use `OR` logic or separate queries.
+
+## Processing Model
+
+- Memories are processed **asynchronously by default** (`async_mode=true`)
+- Add responses return queued events (`ADD`, `UPDATE`, `DELETE`) for tracking
+- Set `async_mode=false` for synchronous processing when needed
+- Graph metadata is processed asynchronously -- use `get_all()` for complete graph data
+
+## Filter System
+
+Filters use nested JSON with a logical operator at the root:
+
+```json
+{
+    "AND": [
+        {"user_id": "alice"},
+        {"categories": {"contains": "finance"}},
+        {"created_at": {"gte": "2024-01-01"}}
+    ]
+}
+```
+
+Root must be `AND`, `OR`, or `NOT`. Simple shorthand `{"user_id": "alice"}` also works.
+
+### Supported Operators
+
+| Operator | Description |
+|----------|-------------|
+| `eq` | Equal to (default) |
+| `ne` | Not equal to |
+| `in` | Matches any value in array |
+| `gt`, `gte` | Greater than / greater than or equal |
+| `lt`, `lte` | Less than / less than or equal |
+| `contains` | Case-sensitive containment |
+| `icontains` | Case-insensitive containment |
+| `*` | Wildcard -- matches any non-null value |
+
+### Filterable Fields
+
+| Field | Valid Operators |
+|-------|-----------------|
+| `user_id`, `agent_id`, `app_id`, `run_id` | `eq`, `ne`, `in`, `*` |
+| `created_at`, `updated_at`, `timestamp` | `gt`, `gte`, `lt`, `lte`, `eq`, `ne` |
+| `categories` | `eq`, `ne`, `in`, `contains` |
+| `metadata` | `eq`, `ne`, `contains` (top-level keys only) |
+| `keywords` | `contains`, `icontains` |
+| `memory_ids` | `in` |
+
+### Filter Constraints
+
+1. **Entity scope partitioning:** `user_id` AND `agent_id` in one `AND` block yields empty results.
+2. **Metadata limitations:** Only top-level keys. Only `eq`, `contains`, `ne`. No `in` or `gt`.
+3. **Operator syntax:** Use `gte`, `lt`, `ne`. SQL-style (`>=`, `!=`) rejected.
+4. **Entity filter required for get-all:** At least one of `user_id`, `agent_id`, `app_id`, or `run_id`.
+5. **Wildcard excludes null:** `*` matches only non-null values.
+6. **Date format:** ISO 8601 (`YYYY-MM-DDTHH:MM:SSZ`). Timezone-naive defaults to UTC.
+
+## Response Formats
+
+### Add Response
+
+```json
+[
+  {
+    "id": "mem_01JF8ZS4Y0R0SPM13R5R6H32CJ",
+    "event": "ADD",
+    "data": { "memory": "The user moved to Austin in 2025." }
+  }
+]
+```
+
+Event types: `ADD`, `UPDATE`, `DELETE`. A single add can trigger multiple events.
+
+### Search Response
+
+```json
+{
+  "results": [
+    {
+      "id": "ea925981-...",
+      "memory": "Is a vegetarian and allergic to nuts.",
+      "user_id": "user123",
+      "categories": ["food", "health"],
+      "score": 0.89,
+      "created_at": "2024-07-26T10:29:36.630547-07:00"
+    }
+  ]
+}
+```
+
+With `enable_graph=true`, includes additional `relations` array with entity relationships.

+
+## Core Concept
+
+Mem0 is a managed memory layer that sits between your AI application and users. Every integration follows the same 3-step loop:
+
+```
+User Input → Retrieve relevant memories → Enrich LLM prompt → Generate response → Store new memories
+```
+
+Mem0 handles the complexity of extraction, deduplication, conflict resolution, and semantic retrieval so your application only needs to call `search()` and `add()`.
+
+**Dual storage architecture:**
+- **Vector store**: Embeddings for semantic similarity search
+- **Graph store** (optional): Entity nodes and relationship edges for structured knowledge
+
+---
+

+```
+
+### Processing modes
+
+**Async (default, `async_mode=True`):**
+- API returns immediately: `{"status": "PENDING", "event_id": "..."}`
+- Processing happens in background
+- Use webhooks for completion notifications
+- Best for: high-throughput, non-blocking workflows
+
+**Sync (`async_mode=False`):**
+- API waits for full processing
+- Returns complete memory object with `id`, `event`, `memory`
+- Best for: real-time access immediately after add
+
+### Extraction modes
+
+**Inferred (`infer=True`, default):**
+- LLM extracts structured facts from conversation
+- Conflict resolution deduplicates and resolves contradictions
+- Best for: natural conversation → memory
+
+**Raw (`infer=False`):**
+- Stores text exactly as provided, no LLM processing
+- Skips conflict resolution — same fact can be stored twice
+- Only `user` role messages are stored; `assistant` messages ignored
+- Best for: bulk imports, pre-structured data, migrations
+
+**Warning:** Don't mix `infer=True` and `infer=False` for the same data — the same fact will be stored twice.

+
+### Retrieval enhancement combinations
+
+| Configuration | Latency | Best for |
+|--------------|---------|----------|
+| Base search only | ~100ms | Simple lookups |
+| `keyword_search=True` | ~110ms | Entity-heavy queries, broad coverage |
+| `rerank=True` | ~250-300ms | User-facing results, top-N precision |
+| `keyword_search=True` + `rerank=True` | ~310ms | Balanced (recommended for most apps) |
+| `rerank=True` + `filter_memories=True` | ~400-500ms | Safety-critical, production systems |
+
+### Implicit null scoping
+
+When you search with `user_id="alice"` only, Mem0 returns memories where `agent_id`, `app_id`, and `run_id` are all null. This prevents cross-scope leakage by default.
+
+To include memories with non-null fields, use explicit filters:
+```python
+# Gets memories for alice regardless of agent/app/run
+filters={"OR": [{"user_id": "alice"}]}
+```
+
+---
+
+## Memory Lifecycle
+
+```
+CREATE ──→ ACTIVE ──→ UPDATE ──→ ACTIVE
+  │           │                     │
+  │           ▼                     ▼
+  │       EXPIRED              EXPIRED
+  │      (still stored,       (still stored,
+  │       not retrieved)       not retrieved)
+  │           │                     │
+  ▼           ▼                     ▼
+DELETE    DELETE               DELETE
+(permanent)
+```
+
+### Creation
+- Triggered by `client.add(messages, user_id="...")`
+- Messages processed through extraction → conflict resolution → storage
+- Gets unique UUID, `created_at` timestamp
+- Optional: custom `timestamp`, `expiration_date`, `metadata`, `immutable`
+
+### Updates
+- `client.update(memory_id, text="...")` replaces text and reindexes
+- `client.batch_update([...])` for up to 1000 memories at once
+- Immutable memories (`immutable=True`) cannot be updated — must delete and re-add
+
+### Deduplication
+- Automatic during `add()` with `infer=True`
+- Conflict resolution merges duplicate facts
+- Latest truth wins when contradictions detected
+- Prevents memory bloat from repeated information
+
+### Expiration
+- Optional `expiration_date` parameter (ISO 8601 or `YYYY-MM-DD`)
+- After expiration: memory NOT returned in searches but remains in storage
+- Useful for time-sensitive info (events, temporary preferences, session state)
+
+### Deletion
+- Single: `client.delete(memory_id)` — permanent, no recovery
+- Batch: `client.batch_delete([memory_ids])` — up to 1000
+- Bulk: `client.delete_all(user_id="alice")` — all memories for entity
+- `delete_all()` without filters raises error to prevent accidental data loss
+
+### History tracking
+- `client.history(memory_id)` returns version timeline
+- Shows all changes: `{previous_value, new_value, action, timestamps}`
+- Useful for audit trails and debugging
+
+---
+
+## Memory Object Structure
+
+```json
+{
+  "id": "uuid-string",
+  "memory": "Extracted memory text",
+  "user_id": "user-identifier",
+  "agent_id": null,
+  "app_id": null,
+  "run_id": null,
+  "metadata": { "source": "chat", "priority": "high" },
+  "categories": ["health", "preferences"],
+  "created_at": "2025-03-12T12:34:56Z",
+  "updated_at": "2025-03-12T12:34:56Z",
+  "expiration_date": null,
+  "immutable": false,
+  "structured_attributes": {
+    "day": 12, "month": 3, "year": 2025,
+    "hour": 12, "minute": 34,
+    "day_of_week": "wednesday",
+    "is_weekend": false,
+    "quarter": 1, "week_of_year": 11
+  },
+  "score": 0.85
+}
+```
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `id` | UUID | Unique identifier, used for update/delete |
+| `memory` | string | Extracted or stored text content |
+| `user_id` | string | Primary entity scope |
+| `agent_id` | string | Agent scope |
+| `app_id` | string | Application scope |
+| `run_id` | string | Session/run scope |
+| `metadata` | object | Custom key-value pairs for filtering |
+| `categories` | array | Auto-assigned or custom category tags |
+| `created_at` | datetime | Creation timestamp |
+| `updated_at` | datetime | Last modification timestamp |
+| `expiration_date` | datetime | Auto-expiry date (stops retrieval, data persists) |
+| `immutable` | boolean | If true, prevents modification |
+| `structured_attributes` | object | Temporal breakdown for time-based queries |
+| `score` | float | Semantic similarity (search results only, 0-1) |
+
+---
+
+## Scoping & Multi-Tenancy
+
+Mem0 separates memories across four dimensions to prevent data mixing:
+
+| Dimension | Field | Purpose | Example |
+|-----------|-------|---------|---------|
+| User | `user_id` | Persistent persona or account | `"customer_6412"` |
+| Agent | `agent_id` | Distinct agent or tool | `"meal_planner"` |
+| App | `app_id` | Product surface or deployment | `"ios_retail_app"` |
+| Session | `run_id` | Short-lived flow or thread | `"ticket-9241"` |
+
+### Storage model
+
+Each entity combination creates separate records. A memory with `user_id="alice"` is stored separately from one with `user_id="alice"` + `agent_id="bot"`.
+
+### Critical: cross-entity queries
+
+```python
+# This returns NOTHING — user and agent memories are stored separately
+filters={"AND": [{"user_id": "alice"}, {"agent_id": "bot"}]}
+
+# Use OR to query multiple scopes
+filters={"OR": [{"user_id": "alice"}, {"agent_id": "bot"}]}
+
+# Use wildcard to include any non-null value
+filters={"AND": [{"user_id": "*"}]}  # All users (excludes null)
+```
+
+### Recommended scoping patterns
+
+```python
+# User-level: persistent preferences
+client.add(messages, user_id="alice")
+
+# Session-level: temporary context
+client.add(messages, user_id="alice", run_id="session_123")
+# Clean up when done: client.delete_all(run_id="session_123")
+
+# Agent-level: agent-specific knowledge
+client.add(messages, agent_id="support_bot", app_id="helpdesk")
+
+# Multi-tenant: full isolation
+client.add(messages, user_id="alice", agent_id="bot", app_id="acme_corp", run_id="ticket_42")
+```
+
+---
+
+## Memory Layers
+
+Mem0 supports three layers of memory, from shortest to longest lived:
+
+### Conversation memory
+- In-flight messages within a single turn
+- Tool calls, chain-of-thought reasoning
+- **Lifetime:** Single response — lost after turn finishes
+- **Managed by:** Your application, not Mem0
+
+### Session memory
+- Short-lived facts for current task or channel
+- Multi-step flows (onboarding, debugging, support tickets)
+- **Lifetime:** Minutes to hours
+- **Managed by:** Mem0 via `run_id` parameter
+- Clean up with `client.delete_all(run_id="session_id")`
+
+### User memory
+- Long-lived knowledge tied to a person or account
+- Personal preferences, account state, compliance details
+- **Lifetime:** Weeks to forever
+- **Managed by:** Mem0 via `user_id` parameter
+- Persists across all sessions and interactions
+
+### How layering works in practice
+
+```python
+def chat(user_input: str, user_id: str, session_id: str) -> str:
+    # 1. Retrieve user memories (long-term preferences)
+    user_mems = mem0.search(user_input, user_id=user_id)
+
+    # 2. Retrieve session memories (current task context)
+    session_mems = mem0.search(user_input, filters={
+        "AND": [{"user_id": user_id}, {"run_id": session_id}]
+    })
+
+    # 3. Combine both layers for LLM context
+    context = format_memories(user_mems) + format_memories(session_mems)
+
+    # 4. Generate response
+    response = llm.generate(context=context, input=user_input)
+
+    # 5. Store in session scope (temporary) + user scope (persistent)
+    messages = [{"role": "user", "content": user_input}, {"role": "assistant", "content": response}]
+    mem0.add(messages, user_id=user_id, run_id=session_id)
+
+    return response
+```
+
+---
+
+## Performance Characteristics
+
+### Latency
+
+| Operation | Typical Latency |
+|-----------|----------------|
+| Base vector search | ~100ms |
+| + keyword_search | +10ms |
+| + reranking | +150-200ms |
+| + filter_memories | +200-300ms |
+| Add (async, default) | < 50ms response, background processing |
+| Add (sync) | 500ms-2s depending on extraction complexity |
+| Graph operations | Slight overhead for large stores |
+
+### Processing
+
+- **Async mode (default):** Returns immediately, processes in background
+- **Sync mode:** Waits for full extraction + storage pipeline
+- **Batch operations:** Up to 1000 memories per batch_update/batch_delete
+- **Webhooks:** Real-time notifications when async processing completes
+
+### Scoping strategy for performance
+
+- Use `user_id` for all user-facing queries (most common, fastest)
+- Add `run_id` for session isolation (narrows search space)
+- Avoid wildcard `"*"` filters on large datasets (scans all non-null records)
+- Use `top_k` to limit result count when you only need a few memories
+
+---
+
+## Comparison with Alternatives
+
+| Approach | Pros | Cons |
+|----------|------|------|
+| **Raw vector DB** | Fast, full control | No extraction, no dedup, no conflict resolution |
+| **In-memory chat history** | Zero latency | Lost on restart, no cross-session, grows unbounded |
+| **RAG over documents** | Good for static knowledge | No personalization, no memory updates |
+| **Mem0 Platform** | Managed extraction + dedup + graph + scoping | External dependency, async processing delay |
+
+Mem0 combines the best of vector search (semantic retrieval) with automatic extraction (LLM-powered), conflict resolution (deduplication), and structured scoping (multi-tenancy) — in a single managed API.

+
+## Advanced Retrieval
+
+Three enhancement options for tuning search precision, recall, and latency.
+
+### Keyword Search (`keyword_search=True`)
+
+Expands results to include memories with specific terms, names, and technical keywords.
+
+- Latency: +10ms
+- Recall: Significantly increased
+- Best for: entity-heavy queries, comprehensive coverage
+
+### Reranking (`rerank=True`)
+
+Deep semantic reordering of results — most relevant first.
+
+- Latency: +150-200ms
+- Accuracy: Significantly improved
+- Best for: user-facing results, top-N precision
+
+### Filter Memories (`filter_memories=True`)
+
+Precision filtering — removes low-relevance results entirely.
+
+- Latency: +200-300ms
+- Precision: Maximized
+- Best for: safety-critical applications, production systems
+
+### Recommended Combinations
+
+**Python:**
+```python
+# Fast & broad
+results = client.search(query, keyword_search=True, user_id="user123")
+
+# Balanced (recommended for most apps)
+results = client.search(query, keyword_search=True, rerank=True, user_id="user123")
+
+# High precision (critical apps)
+results = client.search(query, rerank=True, filter_memories=True, user_id="user123")
+```
+
+**TypeScript:**
+```typescript
+const results = await client.search(query, {
+    user_id: 'user123',
+    keyword_search: true,
+    rerank: true,
+});
+```
+
+---
+
+## Graph Memory
+
+Entity-level knowledge graph that creates relationships between memories.
+
+### How It Works
+
+1. **Extraction**: LLM analyzes conversation and identifies entities and relationships
+2. **Storage**: Embeddings go to vector store; entity nodes and edges go to graph store
+3. **Retrieval**: Vector search returns semantic matches; graph relations are appended to results
+
+Graph relations **augment** vector results without reordering them. Vector similarity always determines hit sequence.
+
+### Enabling Graph Memory
+
+**Per request:**
+```python
+client.add(messages, user_id="alice", enable_graph=True)
+client.search("query", user_id="alice", enable_graph=True)
+client.get_all(filters={"AND": [{"user_id": "alice"}]}, enable_graph=True)
+```
+
+**Project-level (default for all operations):**
+```python
+client.project.update(enable_graph=True)
+```
+
+```javascript
+await client.updateProject({ enable_graph: true });
+```
+
+### Relation Structure
+
+Each relation in the response contains:
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `source` | string | Source entity name |
+| `source_type` | string | Source entity type (e.g., "Person") |
+| `relationship` | string | Relationship label (e.g., "lives_in") |
+| `target` | string | Target entity name |
+| `target_type` | string | Target entity type (e.g., "City") |
+| `score` | number | Confidence score |
+
+**Example:**
+```json
+{
+  "relations": [
+    {
+      "source": "Joseph",
+      "source_type": "Person",
+      "relationship": "lives_in",
+      "target": "Seattle",
+      "target_type": "City",
+      "score": 0.92
+    }
+  ]
+}
+```
+
+### Technical Notes
+
+- Graph Memory adds processing time; see docs for current plan availability
+- Works optimally with rich conversation histories containing entity relationships
+- Best suited for long-running assistants tracking evolving information
+- Graph writes and reads toggle independently per request
+- Multi-agent context supported via `user_id`, `agent_id`, `run_id` scoping
+- Add operations are asynchronous; graph metadata may not be immediately available
+
+---
+
+## Custom Categories
+
+Replace Mem0's default 15 labels with domain-specific categories. The system automatically tags memories to the closest matching category.
+
+### Default Categories (15)
+
+`personal_details`, `family`, `professional_details`, `sports`, `travel`, `food`, `music`, `health`, `technology`, `hobbies`, `fashion`, `entertainment`, `milestones`, `user_preferences`, `misc`
+
+### Configuration
+
+**Set project-level categories:**
+```python
+new_categories = [
+    {"lifestyle_management": "Tracks daily routines, habits, wellness activities"},
+    {"seeking_structure": "Documents goals around creating routines and systems"},
+    {"personal_information": "Basic information about the user"}
+]
+client.project.update(custom_categories=new_categories)
+```
+
+```javascript
+await client.updateProject({ custom_categories: new_categories });
+```
+
+**Retrieve active categories:**
+```python
+categories = client.project.get(fields=["custom_categories"])
+```
+
+### Key Constraint
+
+Per-request overrides (`custom_categories=...` on `client.add`) are **not supported** on the managed API. Only project-level configuration works. Workaround: store ad-hoc labels in `metadata` field.
+
+---
+
+## Custom Instructions
+
+Natural language filters that control what information Mem0 extracts when creating memories.
+
+### Set Instructions
+
+```python
+client.project.update(custom_instructions="Your guidelines here...")
+```
+
+```javascript
+await client.updateProject({ custom_instructions: "Your guidelines here..." });
+```
+
+### Template Structure
+
+1. **Task Description** -- brief extraction overview
+2. **Information Categories** -- numbered sections with specific details to capture
+3. **Processing Guidelines** -- quality and handling rules
+4. **Exclusion List** -- sensitive/irrelevant data to filter out
+
+### Domain Examples
+
+**E-commerce:** Capture product issues, preferences, service experience; exclude payment data.
+
+**Education:** Extract learning progress, student preferences, performance patterns; exclude specific grades.
+
+**Finance:** Track financial goals, life events, investment interests; exclude account numbers and SSNs.
+
+### Best Practices
+
+- Start simply, test with sample messages, iterate based on results
+- Avoid overly lengthy instructions
+- Be specific about what to include AND exclude
+
+---
+
+## Criteria Retrieval
+
+Custom attribute-based memory ranking using LLM-evaluated criteria with weights. Goes beyond semantic similarity to prioritize memories based on domain-specific signals.
+
+### Configuration
+
+```python
+# Define criteria at project level
+retrieval_criteria = [
+    {"name": "joy", "description": "Positive emotions like happiness and excitement", "weight": 3},
+    {"name": "curiosity", "description": "Inquisitiveness and desire to learn", "weight": 2},
+    {"name": "urgency", "description": "Time-sensitive or high-priority items", "weight": 4},
+]
+client.project.update(retrieval_criteria=retrieval_criteria)
+```
+
+```typescript
+await client.updateProject({
+    retrieval_criteria: [
+        { name: 'joy', description: 'Positive emotions', weight: 3 },
+        { name: 'urgency', description: 'Time-sensitive items', weight: 4 },
+    ],
+});
+```
+
+### Usage
+
+Once configured, `client.search()` automatically applies criteria ranking:
+
+```python
+# Criteria-weighted results returned automatically
+results = client.search("Why am I feeling happy?", filters={"user_id": "alice"})
+```
+
+**Best for:** Wellness assistants, tutoring platforms, productivity tools — any app needing intent-aware retrieval.
+
+---
+
+## Feedback Mechanism
+
+Provide feedback on extracted memories to improve system quality over time.
+
+### Feedback Types
+
+| Type | Meaning |
+|------|---------|
+| `POSITIVE` | Memory is useful and accurate |
+| `NEGATIVE` | Memory is not useful |
+| `VERY_NEGATIVE` | Memory is harmful or completely wrong |
+| `None` | Clear existing feedback |
+
+### Usage
+
+**Python:**
+```python
+client.feedback(
+    memory_id="mem-123",
+    feedback="POSITIVE",
+    feedback_reason="Accurately captured dietary preference"
+)
+
+# Bulk feedback
+for item in feedback_data:
+    client.feedback(**item)
+```
+
+**TypeScript:**
+```typescript
+await client.feedback('mem-123', {
+    feedback: 'POSITIVE',
+    feedback_reason: 'Accurately captured dietary preference',
+});
+```
+
+---
+
+## Memory Export
+
+Create structured exports of memories using customizable schemas with filters.
+
+### Usage
+
+```python
+import json
+
+# Define export schema
+schema = {
+    "type": "object",
+    "properties": {
+        "name": {"type": "string"},
+        "preferences": {"type": "array", "items": {"type": "string"}},
+        "health_info": {"type": "string"},
+    }
+}
+
+# Create export
+response = client.create_memory_export(
+    schema=json.dumps(schema),
+    filters={"user_id": "alice"},
+    export_instructions="Create comprehensive profile based on all memories"
+)
+
+# Retrieve export (may take a moment to process)
+result = client.get_memory_export(memory_export_id=response["id"])
+```
+
+**Best for:** Data analytics, user profile generation, compliance audits, CRM sync.
+
+---
+
+## Group Chat
+
+Process multi-participant conversations and automatically attribute memories to individual speakers.
+
+### Usage
+
+```python
+messages = [
+    {"role": "user", "name": "Alice", "content": "I think we should use React for the frontend"},
+    {"role": "user", "name": "Bob", "content": "I prefer Vue.js, it's simpler for our use case"},
+    {"role": "assistant", "content": "Both are great choices. Let me note your preferences."},
+]
+
+# Mem0 automatically attributes memories to each speaker
+response = client.add(messages, run_id="team_meeting_1")
+
+# Retrieve Alice's memories from that session
+alice_mems = client.get_all(
+    filters={"AND": [{"user_id": "alice"}, {"run_id": "team_meeting_1"}]}
+)
+```
+
+Use the `name` field in messages to identify speakers. Mem0 maps names to entity scopes automatically.
+
+---
+
+## MCP Integration
+
+Model Context Protocol integration enables AI clients (Claude Desktop, Cursor, custom agents) to manage Mem0 memory autonomously.
+
+### Configuration
+
+```json
+{
+  "mcpServers": {
+    "mem0": {
+      "command": "uvx",
+      "args": ["mem0-mcp-server"],
+      "env": {
+        "MEM0_API_KEY": "m0-your-api-key",
+        "MEM0_DEFAULT_USER_ID": "your-user-id"
+      }
+    }
+  }
+}
+```
+
+### Available MCP Tools
+
+The MCP server exposes 9 memory tools that AI agents can use autonomously:
+- Add, search, get, update, delete memories
+- Get history, list users, delete users
+- Search Mem0 documentation
+
+### How It Works
+
+1. Configure the MCP server in your AI client
+2. The agent autonomously decides when to store/retrieve memories
+3. No manual API calls needed — the agent manages memory as part of its reasoning
+
+**Best for:** Universal AI client integration — one protocol works everywhere.
+
+---
+
+## Webhooks
+
+Real-time event notifications for memory operations.
+
+### Supported Events
+
+| Event | Trigger |
+|-------|---------|
+| `memory_add` | Memory created |
+| `memory_update` | Memory modified |
+| `memory_delete` | Memory removed |
+| `memory_categorize` | Memory tagged |
+
+### Create Webhook
+
+Note: `project_id` here refers to the Mem0 dashboard project scope for webhooks — not the deprecated client init parameter.
+
+```python
+webhook = client.create_webhook(
+    url="https://your-app.com/webhook",
+    name="Memory Logger",
+    project_id="proj_123",
+    event_types=["memory_add", "memory_categorize"]
+)
+```
+
+### Manage Webhooks
+
+```python
+# Retrieve
+webhooks = client.get_webhooks(project_id="proj_123")
+
+# Update
+client.update_webhook(
+    name="Updated Logger",
+    url="https://your-app.com/new-webhook",
+    event_types=["memory_update", "memory_add"],
+    webhook_id="wh_123"
+)
+
+# Delete
+client.delete_webhook(webhook_id="wh_123")
+```
+
+### Payload Structure
+
+Memory events contain: ID, data object with memory content, event type (`ADD`/`UPDATE`/`DELETE`).
+Categorization events contain: memory ID, event type (`CATEGORIZE`), assigned category labels.
+
+---
+
+## Multimodal Support
+
+Mem0 can process images and documents alongside text.
+
+### Supported Media Types
+
+- Images: JPG, PNG
+- Documents: MDX, TXT, PDF
+
+### Image via URL
+

+# Mem0 Integration Patterns
+
+Working code examples for integrating Mem0 Platform with popular AI frameworks.
+All examples use `MemoryClient` (Platform API key).
+
+Code examples are sourced from official Mem0 integration docs at docs.mem0.ai, simplified for quick reference.
+
+---
+
+## Common Pattern
+
+Every integration follows the same 3-step loop:
+
+1. **Retrieve** -- search relevant memories before generating a response
+2. **Generate** -- include memories as context in the LLM prompt
+3. **Store** -- save the interaction back to Mem0 for future use
+
+---
+
+## LangChain
+
+Source: [docs.mem0.ai/integrations/langchain](https://docs.mem0.ai/integrations/langchain)
+
+```python
+from langchain_openai import ChatOpenAI
+from langchain_core.messages import SystemMessage, HumanMessage
+from langchain_core.prompts import ChatPromptTemplate, MessagesPlaceholder
+from mem0 import MemoryClient
+
+llm = ChatOpenAI(model="gpt-4.1-nano-2025-04-14")
+mem0 = MemoryClient()
+
+prompt = ChatPromptTemplate.from_messages([
+    SystemMessage(content="You are a helpful travel agent AI. Use the provided context to personalize your responses."),
+    MessagesPlaceholder(variable_name="context"),
+    HumanMessage(content="{input}")
+])
+
+def retrieve_context(query: str, user_id: str):
+    """Retrieve relevant memories from Mem0"""
+    memories = mem0.search(query, user_id=user_id)
+    memory_list = memories['results']
+    serialized = ' '.join([m["memory"] for m in memory_list])
+    return [
+        {"role": "system", "content": f"Relevant information: {serialized}"},
+        {"role": "user", "content": query}
+    ]
+
+def chat_turn(user_input: str, user_id: str) -> str:
+    # 1. Retrieve
+    context = retrieve_context(user_input, user_id)
+    # 2. Generate
+    chain = prompt | llm
+    response = chain.invoke({"context": context, "input": user_input})
+    # 3. Store
+    mem0.add(
+        [{"role": "user", "content": user_input}, {"role": "assistant", "content": response.content}],
+        user_id=user_id
+    )
+    return response.content
+```

+
+## CrewAI
+
+Source: [docs.mem0.ai/integrations/crewai](https://docs.mem0.ai/integrations/crewai)
+
+CrewAI has native Mem0 integration via `memory_config`:
+
+```python
+from crewai import Agent, Task, Crew, Process
+from mem0 import MemoryClient
+
+client = MemoryClient()
+
+# Store user preferences first
+messages = [
+    {"role": "user", "content": "I am more of a beach person than a mountain person."},
+    {"role": "assistant", "content": "Noted! I'll recommend beach destinations."},
+    {"role": "user", "content": "I like Airbnb more than hotels."},
+]
+client.add(messages, user_id="crew_user_1")
+
+# Create agent
+travel_agent = Agent(
+    role="Personalized Travel Planner",
+    goal="Plan personalized travel itineraries",
+    backstory="You are a seasoned travel planner.",
+    memory=True,
+)
+
+# Create task
+task = Task(
+    description="Find places to live, eat, and visit in San Francisco.",
+    expected_output="A detailed list of places to live, eat, and visit.",
+    agent=travel_agent,
+)
+
+# Setup crew with Mem0 memory
+crew = Crew(
+    agents=[travel_agent],
+    tasks=[task],
+    process=Process.sequential,
+    memory=True,
+    memory_config={
+        "provider": "mem0",
+        "config": {"user_id": "crew_user_1"},
+    }
+)
+
+result = crew.kickoff()
+```

+Install: `npm install @mem0/vercel-ai-provider`
+
+### Basic Text Generation with Memory
+
+```typescript
+import { generateText } from "ai";
+import { createMem0 } from "@mem0/vercel-ai-provider";
+
+const mem0 = createMem0({
+    provider: "openai",
+    mem0ApiKey: "m0-xxx",

+    prompt: "Suggest me a good car to buy!",
+});
+```
+
+### Streaming with Memory
+
+```typescript
+import { streamText } from "ai";
+import { createMem0 } from "@mem0/vercel-ai-provider";
+
+const mem0 = createMem0();
+
+const { textStream } = streamText({

+
+## LangGraph
+
+Source: [docs.mem0.ai/integrations/langgraph](https://docs.mem0.ai/integrations/langgraph)
+
+State-based agent workflows with memory persistence. Best for complex conversation flows with branching logic.
+
+```python
+from typing import Annotated, TypedDict, List
+from langgraph.graph import StateGraph, START
+from langgraph.graph.message import add_messages
+from langchain_openai import ChatOpenAI
+from mem0 import MemoryClient
+from langchain_core.messages import SystemMessage, HumanMessage, AIMessage
+
+llm = ChatOpenAI(model="gpt-4")
+mem0 = MemoryClient()
+
+class State(TypedDict):
+    messages: Annotated[List[HumanMessage | AIMessage], add_messages]
+    mem0_user_id: str
+
+def chatbot(state: State):
+    messages = state["messages"]
+    user_id = state["mem0_user_id"]
+
+    # Retrieve relevant memories
+    memories = mem0.search(messages[-1].content, user_id=user_id)
+    context = "Relevant context:\n"
+    for memory in memories["results"]:
+        context += f"- {memory['memory']}\n"
+
+    system_message = SystemMessage(content=f"""You are a helpful support assistant.
+{context}""")
+
+    response = llm.invoke([system_message] + messages)
+
+    # Store the interaction
+    mem0.add(
+        [{"role": "user", "content": messages[-1].content},
+         {"role": "assistant", "content": response.content}],
+        user_id=user_id
+    )
+    return {"messages": [response]}
+
+graph = StateGraph(State)
+graph.add_node("chatbot", chatbot)
+graph.add_edge(START, "chatbot")
+app = graph.compile()
+
+# Usage

+## LlamaIndex
+
+Source: [docs.mem0.ai/integrations/llama-index](https://docs.mem0.ai/integrations/llama-index)
+
+Install: `pip install llama-index-core llama-index-memory-mem0`
+
+LlamaIndex has native Mem0 support via `Mem0Memory`. Works with ReAct and FunctionCalling agents.
+
+```python
+from llama_index.memory.mem0 import Mem0Memory
+
+context = {"user_id": "alice", "agent_id": "llama_agent_1"}
+memory = Mem0Memory.from_client(
+    context=context,
+    search_msg_limit=4,  # messages from chat history used for retrieval (default: 5)
+)

+
+# Category filtering (partial match)
+filters={"AND": [{"user_id": "alice"}, {"categories": {"contains": "finance"}}]}
+
+# Category filtering (exact match)
+filters={"AND": [{"user_id": "alice"}, {"categories": {"in": ["personal_information"]}}]}
+
+# Wildcard (match any non-null run)
+filters={"AND": [{"user_id": "alice"}, {"run_id": "*"}]}
+
+# Date range
+filters={"AND": [
+    {"user_id": "alice"},
+    {"created_at": {"gte": "2024-01-01T00:00:00Z"}},
+    {"created_at": {"lt": "2024-02-01T00:00:00Z"}}
+]}
+
+# Exclude categories with NOT
+filters={"AND": [{"user_id": "user_123"}, {"NOT": {"categories": {"in": ["spam", "test"]}}}]}
+
+# Multi-dimensional query
+filters={"AND": [
+    {"user_id": "user_123"},
+    {"keywords": {"icontains": "invoice"}},
+    {"categories": {"in": ["finance"]}},
+    {"created_at": {"gte": "2024-01-01T00:00:00Z"}}
+]}
+```
+
+---
+
+## get() / getAll() -- Retrieve Memories
+
+**Python:**
+```python
+# Single memory by ID
+memory = client.get(memory_id="ea925981-...")
+
+# All memories for a user
+memories = client.get_all(filters={"AND": [{"user_id": "alice"}]})
+
+# With date range
+memories = client.get_all(
+    filters={"AND": [
+        {"user_id": "alex"},
+        {"created_at": {"gte": "2024-07-01", "lte": "2024-07-31"}}
+    ]}
+)
+
+# With graph data
+memories = client.get_all(filters={"AND": [{"user_id": "alice"}]}, enable_graph=True)
+```
+
+**TypeScript:**
+```typescript
+const memory = await client.get("ea925981-...");
+const memories = await client.getAll({ filters: { AND: [{ user_id: "alice" }] } });
+```
+
+**Note:** `get_all` requires at least one of `user_id`, `agent_id`, `app_id`, or `run_id` in filters.
+
+---
+
+## update() -- Modify Memories
+
+**Python:**
+```python
+client.update(memory_id="ea925981-...", text="Updated: vegan since 2024")
+client.update(memory_id="ea925981-...", text="Updated", metadata={"verified": True})
+```
+
+**TypeScript:**
+```typescript
+await client.update("ea925981-...", { text: "Updated: vegan since 2024" });
+```
+
+Cannot update immutable memories.
+
+---
+
+## delete() / deleteAll() -- Remove Memories
+
+**Python:**
+```python
+client.delete(memory_id="ea925981-...")
+client.delete_all(user_id="alice")  # Irreversible bulk delete
+```
+
+**TypeScript:**
+```typescript
+await client.delete("ea925981-...");
+await client.deleteAll({ user_id: "alice" });
+```
+
+---
+
+## history() -- Track Changes
+
+**Python:**
+```python
+history = client.history(memory_id="ea925981-...")
+# Returns: [{previous_value, new_value, action, timestamps}]
+```
+
+**TypeScript:**
+```typescript
+const history = await client.history("ea925981-...");
+```
+
+---
+
+## Batch Operations (TypeScript)
+
+```typescript
+// Batch update
+await client.batchUpdate([
+    { memoryId: "uuid-1", text: "Updated text" },
+    { memoryId: "uuid-2", text: "Another updated text" },
+]);
+
+// Batch delete
+await client.batchDelete(["uuid-1", "uuid-2", "uuid-3"]);
+```
+
+---
+
+## Additional Methods
+
+```python
+# List all users/agents/sessions with memories
+users = client.users()
+
+# Delete a user/agent entity
+client.delete_users(user_id="alice")
+
+# Submit feedback on a memory
+client.feedback(memory_id="...", feedback="POSITIVE", feedback_reason="Accurate extraction")
+
+# Export memories
+export = client.create_memory_export(filters={"AND": [{"user_id": "alice"}]})
+data = client.get_memory_export(memory_export_id=export["id"])
+```
+
+---
+
+## Common Pitfalls
+
+1. **Entity cross-filtering fails silently** -- `AND` with `user_id` + `agent_id` returns empty. Use `OR`.
+2. **SQL operators rejected** -- use `gte`, `lt`, etc. Not `>=`, `<`.
+3. **Metadata filtering is limited** -- only top-level keys with `eq`, `contains`, `ne`.
+4. **Wildcard `*` excludes null** -- only matches non-null values.
+5. **Default threshold is 0.3** -- increase for stricter matching.
+6. **Async processing** -- memories process asynchronously. Wait 2-3s after `add()` before searching.
+7. **Immutable memories** -- cannot be updated or deleted once created.
+
+## Naming Conventions
+
+Python uses `snake_case` (`user_id`, `memory_id`, `get_all`). TypeScript uses `camelCase` for methods (`getAll`, `deleteAll`, `batchUpdate`) but `snake_case` for API parameters (`user_id`, `agent_id`).

+
+## 1. Personalized AI Companion
+
+A fitness coach that remembers goals, preferences, and progress across sessions. Mem0 persists context across app restarts — no session state needed.
+
+### Implementation (Python)
+
+```python
+from mem0 import MemoryClient
+from openai import OpenAI
+
+mem0 = MemoryClient()
+openai_client = OpenAI()
+
+def chat(user_input: str, user_id: str) -> str:
+    # 1. Retrieve relevant memories
+    memories = mem0.search(user_input, user_id=user_id)
+    context = "\n".join([f"- {m['memory']}" for m in memories.get("results", [])])
+
+    # 2. Generate response with memory context
+    system_prompt = f"""You are Ray, a personal fitness coach.
+Use these known facts about the user to personalize your response:
+{context if context else 'No prior context yet.'}"""
+
+    response = openai_client.chat.completions.create(
+        model="gpt-4.1-nano-2025-04-14",
+        messages=[
+            {"role": "system", "content": system_prompt},
+            {"role": "user", "content": user_input},
+        ]
+    )
+    reply = response.choices[0].message.content
+
+    # 3. Store interaction for future context
+    mem0.add(
+        [{"role": "user", "content": user_input}, {"role": "assistant", "content": reply}],
+        user_id=user_id
+    )
+    return reply
+
+# Usage
+chat("I want to run a marathon in under 4 hours", user_id="max")
+# Next day, app restarted:
+chat("What should I focus on today?", user_id="max")
+# Ray remembers the sub-4 marathon goal
+```
+
+### Implementation (TypeScript)
+
+```typescript
+import MemoryClient from 'mem0ai';
+import OpenAI from 'openai';
+
+const mem0 = new MemoryClient({ apiKey: process.env.MEM0_API_KEY! });
+const openai = new OpenAI();
+
+async function chat(userInput: string, userId: string): Promise<string> {
+    // 1. Retrieve relevant memories
+    const memories = await mem0.search(userInput, { user_id: userId });
+    const context = memories.results
+        ?.map((m: any) => `- ${m.memory}`)
+        .join('\n') || 'No prior context yet.';
+
+    // 2. Generate response with memory context
+    const response = await openai.chat.completions.create({
+        model: 'gpt-4.1-nano-2025-04-14',
+        messages: [
+            { role: 'system', content: `You are Ray, a personal fitness coach.\nUser context:\n${context}` },
+            { role: 'user', content: userInput },
+        ],
+    });
+    const reply = response.choices[0].message.content!;
+
+    // 3. Store interaction
+    await mem0.add(
+        [{ role: 'user', content: userInput }, { role: 'assistant', content: reply }],
+        { user_id: userId }
+    );
+    return reply;
+}
+```
+
+### Key Benefits
+
+- Context persists across app restarts — no session management needed
+- Memories are automatically deduplicated and updated
+- Works with any LLM provider (OpenAI, Anthropic, etc.)
+
+**Best for:** Fitness coaches, tutors, therapists — any assistant that needs to remember goals across sessions.
+
+---
+
+## 2. Customer Support with Categories
+
+Auto-categorize support data so teams retrieve the right facts fast. Uses custom categories for structured retrieval.
+
+### Implementation (Python)
+
+```python
+from mem0 import MemoryClient
+
+client = MemoryClient()
+
+# 1. Define categories at the project level (one-time setup)
+custom_categories = [
+    {"support_tickets": "Customer issues and resolutions"},
+    {"account_info": "Account details and preferences"},
+    {"billing": "Payment history and billing questions"},
+    {"product_feedback": "Feature requests and feedback"},
+]
+client.project.update(custom_categories=custom_categories)
+
+# 2. Store interactions — auto-classified into categories
+def log_support_interaction(user_id: str, message: str, priority: str = "normal"):
+    client.add(
+        [{"role": "user", "content": message}],
+        user_id=user_id,
+        metadata={"priority": priority, "source": "support_chat"}
+    )
+
+# 3. Retrieve by category
+def get_billing_issues(user_id: str):
+    return client.get_all(
+        filters={
+            "AND": [
+                {"user_id": user_id},
+                {"categories": {"in": ["billing"]}}
+            ]
+        }
+    )
+
+def search_support_history(user_id: str, query: str):
+    return client.search(
+        query,
+        filters={
+            "AND": [
+                {"user_id": user_id},
+                {"categories": {"contains": "support_tickets"}}
+            ]
+        },
+        top_k=5
+    )
+
+# Usage
+log_support_interaction("maria", "I was charged twice for last month's subscription", priority="high")
+log_support_interaction("maria", "The dashboard is loading slowly on mobile")
+billing = get_billing_issues("maria")  # Returns only billing-related memories
+```
+
+### Implementation (TypeScript)
+
+```typescript
+import MemoryClient from 'mem0ai';
+
+const client = new MemoryClient({ apiKey: process.env.MEM0_API_KEY! });
+
+// Setup categories (one-time)
+await client.updateProject({

+    ],
+});
+
+async function logInteraction(userId: string, message: string, priority = 'normal') {
+    await client.add(

+        filters: { AND: [{ user_id: userId }, { categories: { in: ['billing'] } }] },
+    });
+}
+```
+
+### Key Benefits
+

+
+## 3. Healthcare Coach
+
+Guide patients with an assistant that remembers medical history. Uses high `threshold` for confident retrieval in safety-critical contexts.
+
+### Implementation (Python)
+
+```python
+from mem0 import MemoryClient
+from openai import OpenAI
+
+mem0 = MemoryClient()
+openai_client = OpenAI()
+
+def save_patient_info(user_id: str, information: str):
+    mem0.add(
+        [{"role": "user", "content": information}],
+        user_id=user_id,
+        run_id="healthcare_session",
+        metadata={"type": "patient_information"}
+    )
+
+def consult(user_id: str, question: str) -> str:
+    # High threshold for medical accuracy
+    memories = mem0.search(question, user_id=user_id, top_k=5, threshold=0.7)
+    context = "\n".join([f"- {m['memory']}" for m in memories.get("results", [])])
+
+    response = openai_client.chat.completions.create(
+        model="gpt-4.1-nano-2025-04-14",
+        messages=[
+            {"role": "system", "content": f"You are a health coach. Patient context:\n{context}"},
+            {"role": "user", "content": question},
+        ]
+    )
+    reply = response.choices[0].message.content
+
+    # Store the interaction
+    mem0.add(
+        [{"role": "user", "content": question}, {"role": "assistant", "content": reply}],
+        user_id=user_id,
+        run_id="healthcare_session",
+    )
+    return reply
+
+# Usage
+save_patient_info("alex", "I'm allergic to penicillin and take metformin for type 2 diabetes")
+consult("alex", "Can I take amoxicillin for my sore throat?")
+# Remembers penicillin allergy — amoxicillin is a penicillin-type antibiotic
+```
+
+### Implementation (TypeScript)
+
+```typescript
+import MemoryClient from 'mem0ai';
+import OpenAI from 'openai';
+
+const mem0 = new MemoryClient({ apiKey: process.env.MEM0_API_KEY! });
+const openai = new OpenAI();
+
+async function savePatientInfo(userId: string, info: string) {
+    await mem0.add(
+        [{ role: 'user', content: info }],
+        { user_id: userId, run_id: 'healthcare_session', metadata: { type: 'patient_information' } }
+    );
+}
+
+async function consult(userId: string, question: string): Promise<string> {
+    const memories = await mem0.search(question, {
+        user_id: userId,
+        top_k: 5,
+        threshold: 0.7,
+    });
+    const context = memories.results?.map((m: any) => `- ${m.memory}`).join('\n') || '';
+
+    const response = await openai.chat.completions.create({
+        model: 'gpt-4.1-nano-2025-04-14',
+        messages: [
+            { role: 'system', content: `You are a health coach. Patient context:\n${context}` },
+            { role: 'user', content: question },
+        ],
+    });
+    const reply = response.choices[0].message.content!;
+
+    await mem0.add(
+        [{ role: 'user', content: question }, { role: 'assistant', content: reply }],
+        { user_id: userId, run_id: 'healthcare_session' }
+    );
+    return reply;
+}
+```
+
+### Key Benefits
+
+- High threshold (0.7) ensures only confident matches for safety-critical retrieval
+- Session scoping via `run_id` groups related health interactions
+- Metadata tagging separates patient info from conversation history
+
+**Best for:** Telehealth, wellness apps, patient management — persistent health context across visits.
+
+---
+
+## 4. Content Creation Workflow
+
+Store voice guidelines once and apply them across every draft. Uses `run_id` and `metadata` to scope writing preferences per session.
+
+### Implementation (Python)
+
+```python
+from mem0 import MemoryClient
+from openai import OpenAI
+
+mem0 = MemoryClient()
+openai_client = OpenAI()
+
+def store_writing_preferences(user_id: str, preferences: str):
+    mem0.add(
+        [{"role": "user", "content": preferences}],
+        user_id=user_id,
+        run_id="editing_session",
+        metadata={"type": "preferences", "category": "writing_style"}
+    )
+
+def draft_content(user_id: str, topic: str) -> str:
+    # Retrieve writing preferences
+    prefs = mem0.search(
+        "writing style preferences",
+        filters={"AND": [{"user_id": user_id}, {"run_id": "editing_session"}]}
+    )
+    style_context = "\n".join([f"- {m['memory']}" for m in prefs.get("results", [])])
+
+    response = openai_client.chat.completions.create(
+        model="gpt-4.1-nano-2025-04-14",
+        messages=[
+            {"role": "system", "content": f"Write content matching these style preferences:\n{style_context}"},
+            {"role": "user", "content": f"Write a blog post about: {topic}"},
+        ]
+    )
+    return response.choices[0].message.content
+
+# Usage
+store_writing_preferences("writer_01", "I prefer short sentences. Active voice. No jargon. Use analogies.")
+draft_content("writer_01", "Why AI memory matters for chatbots")
+# Drafts content matching the stored voice guidelines
+```
+
+### Implementation (TypeScript)
+
+```typescript
+import MemoryClient from 'mem0ai';
+import OpenAI from 'openai';
+
+const mem0 = new MemoryClient({ apiKey: process.env.MEM0_API_KEY! });
+const openai = new OpenAI();
+
+async function storePreferences(userId: string, preferences: string) {
+    await mem0.add(
+        [{ role: 'user', content: preferences }],
+        { user_id: userId, run_id: 'editing_session', metadata: { type: 'preferences' } }
+    );
+}
+
+async function draftContent(userId: string, topic: string): Promise<string> {
+    const prefs = await mem0.search('writing style preferences', {
+        filters: { AND: [{ user_id: userId }, { run_id: 'editing_session' }] },
+    });
+    const styleContext = prefs.results?.map((m: any) => `- ${m.memory}`).join('\n') || '';
+
+    const response = await openai.chat.completions.create({
+        model: 'gpt-4.1-nano-2025-04-14',
+        messages: [
+            { role: 'system', content: `Write content matching these preferences:\n${styleContext}` },
+            { role: 'user', content: `Write a blog post about: ${topic}` },
+        ],
+    });
+    return response.choices[0].message.content!;
+}
+```
+
+### Key Benefits
+
+- Voice consistency across all content without repeating guidelines
+- Scoped sessions let you maintain different style profiles
+- Preferences update automatically as you refine them
+
+**Best for:** Marketing teams, technical writers, agencies — consistent voice across all content.
+
+---
+
+## 5. Multi-Agent / Multi-Tenant
+
+Keep memories separate using `user_id`, `agent_id`, `app_id`, and `run_id` scoping. Critical for multi-agent workflows and multi-tenant apps.
+
+### Implementation (Python)
+
+```python
+from mem0 import MemoryClient
+
+client = MemoryClient()
+
+# Store memories scoped to user + agent + session
+def store_scoped_memory(messages: list, user_id: str, agent_id: str, run_id: str, app_id: str):
+    client.add(
+        messages,
+        user_id=user_id,
+        agent_id=agent_id,
+        run_id=run_id,
+        app_id=app_id
+    )
+
+# Query within a specific scope
+def search_user_session(query: str, user_id: str, app_id: str, run_id: str):
+    """Search memories for a specific user within a specific session."""
+    return client.search(
+        query,
+        filters={
+            "AND": [
+                {"user_id": user_id},
+                {"app_id": app_id},
+                {"run_id": run_id}
+            ]
+        }
+    )
+
+def search_agent_knowledge(query: str, agent_id: str, app_id: str):
+    """Search all memories an agent has across all users."""
+    return client.search(
+        query,
+        filters={
+            "AND": [
+                {"agent_id": agent_id},
+                {"app_id": app_id}
+            ]
+        }
+    )
+
+# Usage: Travel concierge app with multiple agents
+store_scoped_memory(
+    [{"role": "user", "content": "I'm vegetarian and prefer window seats"}],
+    user_id="traveler_cam",
+    agent_id="travel_planner",
+    run_id="tokyo-2025",
+    app_id="concierge_app"
+)
+
+# User-scoped query: "What does Cam prefer?"
+user_mems = search_user_session("dietary restrictions?", "traveler_cam", "concierge_app", "tokyo-2025")
+
+# Agent-scoped query: "What do all travelers prefer?" (across users)
+agent_mems = search_agent_knowledge("common dietary restrictions?", "travel_planner", "concierge_app")
+```
+
+### Implementation (TypeScript)
+
+```typescript
+import MemoryClient from 'mem0ai';
+
+const client = new MemoryClient({ apiKey: process.env.MEM0_API_KEY! });
+
+async function storeScopedMemory(
+    messages: Array<{ role: string; content: string }>,
+    userId: string, agentId: string, runId: string, appId: string
+) {
+    await client.add(messages, {
+        user_id: userId,
+        agent_id: agentId,
+        run_id: runId,
+        app_id: appId,
+    });
+}
+
+async function searchUserSession(query: string, userId: string, appId: string, runId: string) {
+    return client.search(query, {
+        filters: { AND: [{ user_id: userId }, { app_id: appId }, { run_id: runId }] },
+    });
+}
+
+async function searchAgentKnowledge(query: string, agentId: string, appId: string) {
+    return client.search(query, {
+        filters: { AND: [{ agent_id: agentId }, { app_id: appId }] },
+    });
+}
+```
+
+### Key Benefits
+
+- Full isolation between users, agents, sessions, and apps
+- Query at any scope level — user, agent, session, or app-wide
+- No memory leakage between tenants
+
+**Best for:** Multi-agent workflows, multi-tenant SaaS — proper isolation at every level.
+
+---
+
+## 6. Personalized Search
+
+Blend real-time search results with personal context. Uses `custom_instructions` to infer preferences from queries.
+
+### Implementation (Python)
+
+```python
+from mem0 import MemoryClient
+from openai import OpenAI
+
+mem0 = MemoryClient()
+openai_client = OpenAI()
+
+# One-time setup: configure Mem0 to infer from queries
+mem0.project.update(
+    custom_instructions="""Infer user preferences and facts from their search queries.
+Extract dietary preferences, location, interests, and purchase history."""
+)
+
+def personalized_search(user_id: str, query: str, search_results: list) -> str:
+    # Get user context from memory
+    memories = mem0.search(query, user_id=user_id, top_k=5)
+    user_context = "\n".join([f"- {m['memory']}" for m in memories.get("results", [])])
+
+    response = openai_client.chat.completions.create(
+        model="gpt-4.1-nano-2025-04-14",
+        messages=[
+            {"role": "system", "content": f"Personalize search results using user context:\n{user_context}"},
+            {"role": "user", "content": f"Query: {query}\n\nSearch results:\n{search_results}"},
+        ]
+    )
+    reply = response.choices[0].message.content
+
+    # Store the query to learn preferences over time
+    mem0.add(
+        [{"role": "user", "content": query}],
+        user_id=user_id
+    )
+    return reply
+
+# Usage
+personalized_search("user_42", "best restaurants nearby", ["Restaurant A", "Restaurant B"])
+# Over time, Mem0 learns: "user prefers vegetarian, lives in Austin"
+# Future searches are automatically personalized
+```
+
+### Implementation (TypeScript)
+
+```typescript
+import MemoryClient from 'mem0ai';
+import OpenAI from 'openai';
+
+const mem0 = new MemoryClient({ apiKey: process.env.MEM0_API_KEY! });
+const openai = new OpenAI();
+
+async function personalizedSearch(userId: string, query: string, searchResults: string[]): Promise<string> {
+    const memories = await mem0.search(query, { user_id: userId, top_k: 5 });
+    const context = memories.results?.map((m: any) => `- ${m.memory}`).join('\n') || '';
+
+    const response = await openai.chat.completions.create({
+        model: 'gpt-4.1-nano-2025-04-14',
+        messages: [
+            { role: 'system', content: `Personalize results using user context:\n${context}` },
+            { role: 'user', content: `Query: ${query}\nResults: ${searchResults.join(', ')}` },
+        ],
+    });
+    const reply = response.choices[0].message.content!;
+
+    await mem0.add([{ role: 'user', content: query }], { user_id: userId });
+    return reply;
+}
+```
+
+### Key Benefits
+
+- Learns preferences from queries automatically via `custom_instructions`
+- Personalizes any search provider (Tavily, Google, Bing)
+- Zero manual preference setup — improves over time
+
+**Best for:** Personalized search engines, recommendation systems — search results tailored to individual users.
+
+---
+
+## 7. Email Intelligence
+
+Capture, categorize, and recall inbox threads using persistent memories with rich metadata.
+
+### Implementation (Python)
+
+```python
+from mem0 import MemoryClient
+
+client = MemoryClient()
+
+def store_email(user_id: str, sender: str, subject: str, body: str, date: str):
+    client.add(
+        [{"role": "user", "content": f"Email from {sender}: {subject}\n\n{body}"}],
+        user_id=user_id,
+        metadata={"email_type": "incoming", "sender": sender, "subject": subject, "date": date}
+    )
+
+def search_emails(user_id: str, query: str):
+    return client.search(
+        query,
+        filters={"AND": [{"user_id": user_id}, {"categories": {"contains": "email"}}]},
+        top_k=10
+    )
+
+def get_emails_from_sender(user_id: str, sender: str):
+    return client.get_all(
+        filters={
+            "AND": [
+                {"user_id": user_id},
+                {"metadata": {"contains": sender}}
+            ]
+        }
+    )
+
+# Usage
+store_email("alice", "bob@acme.com", "Q3 Budget Review", "Attached is the Q3 budget...", "2025-01-15")
+store_email("alice", "carol@acme.com", "Sprint Planning", "Here are the priorities...", "2025-01-16")
+
+results = search_emails("alice", "budget discussions")
+sender_emails = get_emails_from_sender("alice", "bob@acme.com")
+```
+
+### Implementation (TypeScript)
+
+```typescript
+import MemoryClient from 'mem0ai';
+
+const client = new MemoryClient({ apiKey: process.env.MEM0_API_KEY! });
+
+async function storeEmail(userId: string, sender: string, subject: string, body: string, date: string) {
+    await client.add(
+        [{ role: 'user', content: `Email from ${sender}: ${subject}\n\n${body}` }],
+        { user_id: userId, metadata: { email_type: 'incoming', sender, subject, date } }
+    );
+}
+
+async function searchEmails(userId: string, query: string) {
+    return client.search(query, {
+        filters: { AND: [{ user_id: userId }, { categories: { contains: 'email' } }] },
+        top_k: 10,
+    });
+}
+```
+
+### Key Benefits
+
+- Rich metadata enables multi-dimensional queries (sender, date, subject)
+- Category filtering separates emails from other memory types
+- Semantic search across all email content
+
+**Best for:** Inbox management, email automation — searchable email memories with metadata filtering.
+
+---
+
+## Common Patterns Across Use Cases
+
+### Pattern 1: Retrieve → Generate → Store
+
+Every use case follows the same 3-step loop:
+
+```python
+# 1. Retrieve relevant context
+memories = mem0.search(user_input, user_id=user_id)
+context = "\n".join([m["memory"] for m in memories.get("results", [])])
+
+# 2. Generate with context
+response = llm.generate(system_prompt=f"Context:\n{context}", user_input=user_input)
+
+# 3. Store the interaction
+mem0.add(
+    [{"role": "user", "content": user_input}, {"role": "assistant", "content": response}],
+    user_id=user_id
+)
+```
+
+### Pattern 2: Scope with Entity Identifiers
+
+Use `user_id`, `agent_id`, `app_id`, and `run_id` to isolate memories:
+
+```python
+# User-level: personal preferences
+client.add(messages, user_id="alice")
+
+# Session-level: conversation within one session
+client.add(messages, user_id="alice", run_id="session_123")
+
+# Agent-level: agent-specific knowledge
+client.add(messages, agent_id="support_bot", app_id="helpdesk")
+```
+
+### Pattern 3: Rich Metadata for Filtering
+
+Attach structured metadata for multi-dimensional queries:
+
+```python
+# Store with metadata
+client.add(messages, user_id="alice", metadata={"priority": "high", "source": "phone_call"})
+
+# Filter by category + metadata
+client.search("billing issues", filters={
+    "AND": [{"user_id": "alice"}, {"categories": {"contains": "billing"}}]
+})
+```
+
+### Pattern 4: Custom Instructions for Domain-Specific Extraction
+
+Control what Mem0 extracts from conversations:
+
+```python
+client.project.update(
+    custom_instructions="Extract medical conditions, medications, and allergies. Exclude billing info."
+)
+```
