+title: Multi-User Collaboration with Mem0
+---
+
+<Snippet file="paper-release.mdx" />
+
+## Overview
+
+Build a multi-user collaborative chat or task management system with Mem0. Each message is attributed to its author, and all messages are stored in a shared project space. Mem0 makes it easy to track contributions, sort and group messages, and collaborate in real time.
+
+## Setup
+
+Install the required packages:
+
+```bash
+pip install openai mem0ai
+```
+
+## Full Code Example
+
+```python
+from openai import OpenAI
+from mem0 import Memory
+import os
+from datetime import datetime
+from collections import defaultdict
+

+        self.mem = mem
+
+    def add_message(self, role, name, content):
+        msg = {"role": role, "name": name, "content": content}

+            for m in mems:
+                ts = m.get('created_at', 'Timestamp N/A')
+                try:
+                    dt = datetime.fromisoformat(ts.replace('Z', '+00:00'))
+                    ts_fmt = dt.strftime('%Y-%m-%d %H:%M:%S')
+                except Exception:
+                    ts_fmt = ts
+                print(f"[{ts_fmt}] {m['memory']}")
+```
+
+## Usage
+
+```python
+# Example usage
+agent = CollaborativeAgent(RUN_ID)
+agent.add_message("user", "alice", "Let's list tasks for the new landing page.")
+agent.add_message("user", "bob", "I'll own the hero section copy.")
+agent.add_message("user", "carol", "I'll choose product screenshots.")
+
+# Brainstorm with context
+print("\nAssistant reply:\n", agent.brainstorm("What are the current open tasks?"))
+
+# Print all messages sorted by time
+agent.print_sorted_by_time()
+
+# Print all messages grouped by actor
+agent.print_grouped_by_actor()
+```
+
+## Key Points
+
+- Each message is attributed to a user or agent (actor)
+- All messages are stored in a shared project space (`run_id`)
+- You can sort messages by time, group by actor, and format timestamps for clarity
+- Mem0 makes it easy to build collaborative, attributed chat/task systems
+
+## Conclusion
+
+Mem0 enables fast, transparent collaboration for teams and agents, with full attribution, flexible memory search, and easy message organization.

+title: 'Healthcare Assistant with Mem0 and Google ADK'
+description: 'Build a personalized healthcare agent that remembers patient information across conversations using Mem0 and Google ADK'
+---
+
+<Snippet file="paper-release.mdx" />
+
+# Healthcare Assistant with Memory
+
+This example demonstrates how to build a healthcare assistant that remembers patient information across conversations using Google ADK and Mem0.
+
+## Overview
+
+The Healthcare Assistant helps patients by:
+- Remembering their medical history and symptoms
+- Providing general health information
+- Scheduling appointment reminders
+- Maintaining a personalized experience across conversations
+
+By integrating Mem0's memory layer with Google ADK, the assistant maintains context about the patient without requiring them to repeat information.
+
+## Setup
+
+Before you begin, make sure you have:
+
+Installed Google ADK and Mem0 SDK:
+```bash
+pip install google-adk
+pip install mem0ai
+```
+
+## Code Breakdown
+
+Let's get started and understand the different components required in building a healthcare assistant powered by memory
+
+```python
+# Import dependencies
+import os
+from google.adk.agents import Agent
+from google.adk.sessions import InMemorySessionService
+from google.adk.runners import Runner
+from google.genai import types
+from mem0 import MemoryClient
+
+# Set up API keys (replace with your actual keys)
+os.environ["GOOGLE_API_KEY"] = "your-google-api-key"
+os.environ["MEM0_API_KEY"] = "your-mem0-api-key"
+
+# Define a global user ID for simplicity
+USER_ID = "Alex"
+
+# Initialize Mem0 client
+mem0_client = MemoryClient()
+```
+
+## Define Memory Tools
+
+First, we'll create tools that allow our agent to store and retrieve information using Mem0:
+
+```python
+def save_patient_info(information: str) -> dict:
+    """Saves important patient information to memory."""
+
+    # Store in Mem0
+    response = mem0_client.add(
+        [{"role": "user", "content": information}],
+        user_id=USER_ID,
+        run_id="healthcare_session",
+        metadata={"type": "patient_information"}
+    )
+
+
+def retrieve_patient_info(query: str) -> dict:
+    """Retrieves relevant patient information from memory."""
+
+    # Search Mem0
+    results = mem0_client.search(
+        query,
+        user_id=USER_ID,
+        limit=5,
+        threshold=0.7,  # Higher threshold for more relevant results
+        output_format="v1.1"
+    )
+
+    # Format and return the results
+    if results and len(results) > 0:
+        memories = [memory["memory"] for memory in results.get('results', [])]
+        return {
+            "status": "success",
+            "memories": memories,
+            "count": len(memories)
+        }
+    else:
+        return {
+            "status": "no_results",
+            "memories": [],
+            "count": 0
+        }
+```
+
+## Define Healthcare Tools
+
+Next, we'll add tools specific to healthcare assistance:

+    ):
+        if event.is_final_response():
+            if event.content and event.content.parts:
+                response = event.content.parts[0].text
+                print(f"<<< Assistant: {response}")
+                return response
+
+    return "No response received."
+
+# Example conversation flow
+async def run_conversation():
+    # First interaction - patient introduces themselves with key information
+    await call_agent_async(
+        "Hi, I'm Alex. I've been having headaches for the past week, and I have a penicillin allergy.",
+        runner=runner,
+        user_id=USER_ID,
+        session_id=SESSION_ID
+    )
+
+    # Request for health information
+    await call_agent_async(
+        "Can you tell me more about what might be causing my headaches?",
+        runner=runner,
+        user_id=USER_ID,
+        session_id=SESSION_ID
+    )
+
+    # Schedule an appointment
+    await call_agent_async(
+        "I think I should see a doctor. Can you help me schedule an appointment for next Monday at 2pm?",
+        runner=runner,

+        session_id=SESSION_ID
+    )
+
+    # Test memory - should remember patient name, symptoms, and allergy
+    await call_agent_async(
+        "What medications should I avoid for my headaches?",
+        runner=runner,

+        session_id=SESSION_ID
+    )
+
+# Run the conversation example
+if __name__ == "__main__":
+    asyncio.run(run_conversation())
+```
+
+## How It Works
+
+This healthcare assistant demonstrates several key capabilities:
+
+1. **Memory Storage**: When Alex mentions her headaches and penicillin allergy, the agent stores this information in Mem0 using the `save_patient_info` tool.
+
+2. **Contextual Retrieval**: When Alex asks about headache causes, the agent uses the `retrieve_patient_info` tool to recall her specific situation.
+
+3. **Memory Application**: When discussing medications, the agent remembers Alex's penicillin allergy without her needing to repeat it, providing safer and more personalized advice.
+
+4. **Conversation Continuity**: The agent maintains context across the entire conversation session, creating a more natural and efficient interaction.
+
+## Key Implementation Details
+
+### User ID Management
+
+Instead of passing the user ID as a parameter to the memory tools (which would require modifying the ADK's tool calling system), we attach it directly to the function object:
+
+```python
+# Set user_id for tools to access
+save_patient_info.user_id = user_id
+retrieve_patient_info.user_id = user_id
+```
+
+Inside the tool functions, we retrieve this attribute:
+
+```python
+# Get user_id from session state or use default
+user_id = getattr(save_patient_info, 'user_id', 'default_user')
+```
+
+This approach allows our tools to maintain user context without complicating their parameter signatures.
+
+### Mem0 Integration
+
+The integration with Mem0 happens through two primary functions:
+
+1. `mem0_client.add()` - Stores new information with appropriate metadata
+2. `mem0_client.search()` - Retrieves relevant memories using semantic search
+
+The `threshold` parameter in the search function ensures that only highly relevant memories are returned.
+
+## Conclusion
+
+This example demonstrates how to build a healthcare assistant with persistent memory using Google ADK and Mem0. The integration allows for a more personalized patient experience by maintaining context across conversation turns, which is particularly valuable in healthcare scenarios where continuity of information is crucial.
+
+By storing and retrieving patient information intelligently, the assistant provides more relevant responses without requiring the patient to repeat their medical history, symptoms, or preferences.

+
+Mem0's **Criteria Retrieval** feature allows you to retrieve memories based on specific criteria. This is useful when you need to find memories that match certain conditions or criteria, such as emotional content, sentiment, or other custom attributes.
+
+## Setting Up Custom Criteria
+
+You can define custom criteria at the project level, assigning weights to each criterion. These weights will be normalized during memory retrieval.
+
+```python
+from mem0 import MemoryClient
+
+client = MemoryClient(
+    api_key="mem0_api_key",
+    org_id="mem0_organization_id",
+    project_id="mem0_project_id"
+)
+
+# Define custom criteria with weights
+retrieval_criteria = [
+    {
+        "name": "joy",
+        "description": "Measure the intensity of positive emotions such as happiness, excitement, or amusement expressed in the sentence. A higher score reflects greater joy.",
+        "weight": 3
+    },
+    {
+        "name": "curiosity",
+        "description": "Assess the extent to which the sentence reflects inquisitiveness, interest in exploring new information, or asking questions. A higher score reflects stronger curiosity.",
+        "weight": 2
+    },
+    {
+        "name": "emotion",
+        "description": "Evaluate the presence and depth of sadness or negative emotional tone, including expressions of disappointment, frustration, or sorrow. A higher score reflects greater sadness.",
+        "weight": 1
+    }
+]
+
+# Update project with custom criteria
+client.update_project(
+    retrieval_criteria=retrieval_criteria
+)
+```
+
+## Using Criteria Retrieval
+
+After setting up your criteria, you can use them to filter and retrieve memories. Here's an example:
+
+```python
+# Add some example memories
+messages = [
+    {"role": "user", "content": "What a beautiful sunny day! I feel so refreshed and ready to take on anything!"},
+    {"role": "user", "content": "I've always wondered how storms form—what triggers them in the atmosphere?"},
+    {"role": "user", "content": "It's been raining for days, and it just makes everything feel heavier."},
+    {"role": "user", "content": "Finally I get time to draw something today, after a long time!! I am super happy today."}
+]
+
+client.add(messages, user_id="alice")
+
+# Search with criteria-based filtering
+filters = {
+    "AND": [
+        {"user_id": "alice"}
+    ]
+}
+results_with_criteria = client.search(
+    query="Why I am feeling happy today?", 
+    filters=filters, 
+    version="v2"
+)
+
+# Standard search without criteria filtering
+results_without_criteria = client.search(
+    query="Why I am feeling happy today?", 
+    user_id="alice"
+)
+```
+
+## Search Results Comparison
+
+Let's compare the results from criteria-based retrieval versus standard retrieval to see how the emotional criteria affects ranking:
+
+### Search Results (with Criteria)
+```python
+[
+    {
+        "memory": "User feels refreshed and ready to take on anything on a beautiful sunny day",
+        "score": 0.666,
+        ...
+    },
+    {
+        "memory": "User finally has time to draw something after a long time",
+        "score": 0.616,
+        ...
+    },
+    {
+        "memory": "User is happy today",
+        "score": 0.500,
+        ...
+    },
+    {
+        "memory": "User is curious about how storms form and what triggers them in the atmosphere.",
+        "score": 0.400,
+        ...
+    },
+    {
+        "memory": "It has been raining for days, making everything feel heavier.",
+        "score": 0.116,
+        ...
+    }
+]
+```
+
+### Search Results (without Criteria)
+```python
+[
+    {
+        "memory": "User is happy today",
+        "score": 0.607,
+        ...
+    },
+    {
+        "memory": "User feels refreshed and ready to take on anything on a beautiful sunny day",
+        "score": 0.512,
+        ...
+    },
+    {
+        "memory": "It has been raining for days, making everything feel heavier.",
+        "score": 0.4617,
+        ...
+    },
+    {
+        "memory": "User is curious about how storms form and what triggers them in the atmosphere.",
+        "score": 0.340,
+        ...
+    },
+    {
+        "memory": "User finally has time to draw something after a long time",
+        "score": 0.336,
+        ...
+    }
+]
+```
+
+Looking at the example results above, we can see how criteria-based filtering affects the output:
+
+1. **Memory Ordering**: With criteria, memories with high joy scores (like feeling refreshed and drawing) are ranked higher, while without criteria, the most relevant memory ("User is happy today") comes first.
+
+2. **Score Distribution**: With criteria, scores are more spread out (0.116 to 0.666) and reflect the criteria weights, while without criteria, scores are more clustered (0.336 to 0.607) and based purely on relevance.
+
+3. **Negative Content**: With criteria, the negative memory about rain has a much lower score (0.116) due to the emotion criteria, while without criteria it maintains a relatively high score (0.4617) due to its relevance.
+
+4. **Curiosity Content**: The storm-related memory gets a moderate score (0.400) with criteria due to the curiosity weighting, while without criteria it's ranked lower (0.340) as it's less relevant to the happiness query.
+
+## Key Differences
+
+1. **Scoring**: With criteria, normalized scores (0-1) are used based on custom criteria weights, while without criteria, standard relevance scoring is used
+
+2. **Ordering**: With criteria, memories are first retrieved by relevance, then criteria-based filtering and prioritization is applied, while without criteria, ordering is solely by relevance
+
+3. **Filtering**: With criteria, post-retrieval filtering based on custom criteria (joy, curiosity, etc.) is available, which isn't available without criteria
+
+<Note>
+When no custom criteria are specified, the search will default to standard relevance-based retrieval. In this case, results are returned based solely on their relevance to the query, without any additional filtering or prioritization that would normally be applied through criteria.
+</Note>
+
+## How It Works
+
+1. **Criteria Definition**: Define custom criteria with names, descriptions, and weights
+2. **Project Configuration**: Apply these criteria at the project level
+3. **Memory Retrieval**: Use v2 search with filters to retrieve memories based on your criteria
+4. **Weighted Scoring**: Memories are scored based on the defined criteria weights
+
+<Note>
+Criteria retrieval is currently supported only in search v2. Make sure to use `version="v2"` when performing searches with custom criteria.

+## Easy Setup
+
+### Prerequisites
+- Docker
+- OpenAI API Key
+
+You can quickly run OpenMemory by running the following command:
+
+```bash
+curl -sL https://raw.githubusercontent.com/mem0ai/mem0/main/openmemory/run.sh | bash
+```
+
+You should set the `OPENAI_API_KEY` as a global environment variable:
+
+```bash
+export OPENAI_API_KEY=your_api_key
+```
+
+You can also set the `OPENAI_API_KEY` as a parameter to the script:
+
+```bash
+curl -sL https://raw.githubusercontent.com/mem0ai/mem0/main/openmemory/run.sh | OPENAI_API_KEY=your_api_key bash
+```
