 ## App Types
 
-We have three types of App.
+Embedchain supports a variety of LLMs, embedding functions/models and vector databases.
 
-### App
+Our app gives you full control over which components you want to use, you can mix and match them to your hearts content.
+
+<Tip>
+Out of the box, if you just use `app = App()`, Embedchain uses what we believe to be the best configuration available. This might include paid/proprietary components. Currently, this is
+
+* LLM: OpenAi (gpt-3.5-turbo-0613)
+* Embedder: OpenAi (text-embedding-ada-002)
+* Database: ChromaDB
+</Tip>
+
+### LLM
+
+#### Choosing an LLM
+
+The following LLM providers are supported by Embedchain:
+- OPENAI
+- ANTHPROPIC
+- VERTEX_AI
+- GPT4ALL
+- AZURE_OPENAI
+- LLAMA2
+
+You can choose one by importing it from `embedchain.llm`. E.g.:
 
 ```python
 from embedchain import App
-app = App()
+from embedchain.llm.llama2 import Llama2Llm
+
+app = App(llm=Llama2Llm())
 ```
 
-- `App` uses OpenAI's model, so these are paid models. 💸 You will be charged for embedding model usage and LLM usage.
-- `App` uses OpenAI's embedding model to create embeddings for chunks and ChatGPT API as LLM to get answer given the relevant docs. Make sure that you have an OpenAI account and an API key. If you have don't have an API key, you can create one by visiting [this link](https://platform.openai.com/account/api-keys).
-- `App` is opinionated. It uses the best embedding model and LLM on the market.
-- Once you have the API key, set it in an environment variable called `OPENAI_API_KEY`
+#### Configuration
+
+The LLMs can be configured by passing an LlmConfig object.
+
+The config options can be found [here](/advanced/query_configuration#llmconfig)
 
 ```python
-import os
-os.environ["OPENAI_API_KEY"] = "sk-xxxx"
+from embedchain import App
+from embedchain.llm.llama2 import Llama2Llm
+from embedchain.config import LlmConfig
+
+app = App(llm=Llama2Llm(), llm_config=LlmConfig(number_documents=3, temperature=0))
 ```
 
-### Llama2App
+### Embedder
+
+#### Choosing an Embedder
+
+The following providers for embedding functions are supported by Embedchain:
+- OPENAI
+- HUGGING_FACE
+- VERTEX_AI
+- GPT4ALL
+- AZURE_OPENAI
+
+You can choose one by importing it from `embedchain.embedder`. E.g.:
 
 ```python
-import os

-zuck_bot.query("Who is Mark Zuckerberg?")
-# Answer: Mark Zuckerberg is an American internet entrepreneur and business magnate. He is the co-founder and CEO of Facebook. Born in 1984, he dropped out of Harvard University to focus on his social media platform, which has since grown to become one of the largest and most influential technology companies in the world.

-- `OpenSourceApp` uses open source embedding and LLM model. It uses `all-MiniLM-L6-v2` from Sentence Transformers library as the embedding model and `gpt4all` as the LLM.
-- Here there is no need to setup any api keys. You just need to install embedchain package and these will get automatically installed. 📦
-- Once you have imported and instantiated the app, every functionality from here onwards is the same for either type of app. 📚
-- `OpenSourceApp` is opinionated. It uses the best open source embedding model and LLM on the market.
-- extra dependencies are required for this app type. Install them with `pip install embedchain[opensource]`.
+<Tip>
+You can also pass an `LlmConfig` instance directly to the `query` or `chat` method.
+This creates a temporary config for that request alone, so you could, for example, use a different model (from the same provider) or get more context documents for a specific query.
+</Tip>
 
-### CustomApp
+### Vector Database
+
+#### Choosing a Vector Database
+
+The following vector databases are supported by Embedchain:
+- ChromaDB
+- Elasticsearch
+
+You can choose one by importing it from `embedchain.vectordb`. E.g.:
 
 ```python
-from embedchain import CustomApp
-from embedchain.config import CustomAppConfig
-from embedchain.models import Providers, EmbeddingFunctions
+from embedchain import App
+from embedchain.vectordb.elasticsearch import ElasticsearchDB
 
-config = CustomAppConfig(embedding_fn=EmbeddingFunctions.OPENAI, provider=Providers.OPENAI)
-app = CustomApp(config)
+app = App(db=ElasticsearchDB())
 ```
 
-- `CustomApp` is not opinionated.
-- Configuration required. It's for advanced users who want to mix and match different embedding models and LLMs. Configuration required.
-- while it's doing that, it's still providing abstractions through `Providers`.
-- paid and free/open source providers included.
-- Once you have imported and instantiated the app, every functionality from here onwards is the same for either type of app. 📚
-- Following providers are available for an LLM

-    - OPENAI
-    - HUGGING_FACE
-    - VERTEX_AI
-    - GPT4ALL
-    - AZURE_OPENAI
+#### Configuration
 
+The vector databases can be configured by passing a specific config object.
+
+These vary greatly between the different vector databases.
+
+```python
+from embedchain import App
+from embedchain.vectordb.elasticsearch import ElasticsearchDB

-#### Compatibility with other apps
+### Full Configuration Examples
+
+Embedchain previously offered fully configured classes, namely `App`, `OpenSourceApp`, `CustomApp` and `Llama2App`.
+We deprecated these apps. The reason for this decision was that it was hard to switch from to a different LLM, embedder or vector db, if you one day decided that that's what you want to do.
+The new app allows drop-in replacements, such as changing `App(llm=OpenAiLlm())` to `App(llm=Llama2Llm())`.
+
+To make the switch to our new, fully configurable app easier, we provide you with full examples for what the old classes would look like implemented as a new app.
+You can swap these in, and if you decide you want to try a different model one day, you don't have to rewrite your whole bot.
+
+#### App
+App without any configuration is still using the best options available, so you can keep using:
+
+```python
+from embedchain import App
+
+app = App()
+```
+
+#### OpenSourceApp
+
+Use this snippet to run an open source app.
+
+```python
+from embedchain import App
+from embedchain.llm.gpt4all import GPT4ALLLlm
+from embedchain.embedder.gpt4all import GPT4AllEmbedder
+from embedchain.vectordb.chroma import ChromaDB
+
+app = App(llm=GPT4ALLLlm(), embedder=GPT4AllEmbedder(), db=ChromaDB())
+```
+
+#### Llama2App
+```python
+from embedchain import App
+from embedchain.llm.llama2 import Llama2Llm
+
+app = App(llm=Llama2Llm())
+```
+
+#### CustomApp
+
+Every app is a custom app now.
+If you were previously using a `CustomApp`, you can now just change it to `App`.
+
+Here's one example, what you could do if we combined everything shown on this page.
+
+```python
+from embedchain import App
+from embedchain.config import ElasticsearchDBConfig, EmbedderConfig, LlmConfig
+from embedchain.embedder.openai import OpenAiEmbedder

+    db=ElasticsearchDB(),
+    db_config=ElasticsearchDBConfig(),
+)
+```
+
+### Compatibility with other apps
 
 - If there is any other app instance in your script or app, you can change the import as

 Embedchain is made to work out of the box. However, for advanced users we're also offering configuration options. All of these configuration options are optional and have sane defaults.
 
+## Concept
+The main `App` class is available in the following varieties: `CustomApp`, `OpenSourceApp` and `Llama2App` and `App`. The first is fully configurable, the others are opinionated in some aspects.
+
+The `App` class has three subclasses: `llm`, `db` and `embedder`. These are the core ingredients that make up an EmbedChain app.
+App plus each one of the subclasses have a `config` attribute.
+You can pass a `Config` instance as an argument during initialization to persistently configure a class.
+These configs can be imported from `embedchain.config`
+
+There are `set` methods for some things that should not (only) be set at start-up, like `app.db.set_collection_name`.

+
+In order to use `Elasticsearch` as vector database we need to use App type `CustomApp`.
+

+ELASTICSEARCH_API_KEY=SECRETKEY==
+ELASTICSEARCH_URL=https://secret-domain.europe-west3.gcp.cloud.es.io:443
+```
+Please note that the key needs certain privileges. For testing you can just toggle off `restrict privileges` under `/app/management/security/api_keys/` in your web interface.
+
+2. Load the app
+```python

+---
+
+### 🚀 Getting started
+
+1. Install embedchain python package:
+
+```bash
+pip install --upgrade "embedchain[poe]"
+```
+
+2. Create a free account on [Poe](https://www.poe.com?utm_source=embedchain).
+3. Click "Create Bot" button on top left.
+4. Give it a handle and an optional description.
+5. Select `Use API`.
+6. Under `API URL` enter your server or ngrok address. You can use your machine's public IP or DNS. Otherwise, employ a proxy server like [ngrok](https://ngrok.com/) to make your local bot accessible.
+7. Copy your api key and paste it in `.env` as `POE_API_KEY`.
+8. You will need to set `OPENAI_API_KEY` for generating embeddings and using LLM. Copy your OpenAI API key from [here](https://platform.openai.com/account/api-keys) and paste it in `.env` as `OPENAI_API_KEY`.
+9. Now create your bot using the following code snippet.
+
+```bash
+# make sure that you have set OPENAI_API_KEY and POE_API_KEY in .env file
+from embedchain.bots import PoeBot
+
+poe_bot = PoeBot()
+
+# add as many data sources as you want
+poe_bot.add("https://en.wikipedia.org/wiki/Adam_D%27Angelo")
+poe_bot.add("https://www.youtube.com/watch?v=pJQVAqmKua8")
+
+# start the bot
+# this start the poe bot server on port 8080 by default
+poe_bot.start()
+```
+
+10. You can paste the above in a file called `your_script.py` and then simply do
+
+```bash
+python your_script.py
+```
+
+Now your bot will start running at port `8080` by default.
+
+11. You can refer the [Supported Data formats](https://docs.embedchain.ai/advanced/data_types) section to refer the supported data types in embedchain.
+
+12. Click `Run check` to make sure your machine can be reached.
+13. Make sure your bot is private if that's what you want.
+14. Click `Create bot` at the bottom to finally create the bot
+15. Now your bot is created.
+
+### 💬 How to use
+
+- To ask the bot questions, just type your query in the Poe interface:
+```text
+<your-question-here>
+```
+
+- If you wish to add more data source to the bot, simply update your script and add as many `.add` as you like. You need to restart the server.

+4. On the left Sidebar, go to `OAuth and Permissions` and add the following scopes under `Bot Token Scopes`:
 ```text
 app_mentions:read
 channels:history
 channels:read
 chat:write
 ```
-- Now select the option `Install to Workspace` and after it's done, copy the `Bot User OAuth Token` and set it in your secrets as `SLACK_BOT_TOKEN`.
-- Start your replit container now by clicking on `Run`.
-- On the Slack API website go to `Event Subscriptions` on the left Sidebar and turn on `Enable Events`.
-- Copy the generated server URL in replit, append `/chat` at its end and paste it in `Request URL` box.
-- After it gets verified, click on `Subscribe to bot events`, add `message.channels` Bot User Event and click on `Save Changes`.
-- Now go to your workspace, click on the bot name in the Sidebar and then add the bot to any channel you want.
+5. Now select the option `Install to Workspace` and after it's done, copy the `Bot User OAuth Token` and set it in your secrets as `SLACK_BOT_TOKEN`.
+6. Run your bot now with `python3 -m embedchain.bots.slack`
+7. Expose your bot to the internet. Default port is `5000`, which can be changed by adding `port --8080` to the startup command. You can use your machine's public IP or DNS. Otherwise, employ a proxy server like [ngrok](https://ngrok.com/) to make your local bot accessible.
+8. On the Slack API website go to `Event Subscriptions` on the left Sidebar and turn on `Enable Events`.
+9. In `Request URL`, enter your server or ngrok address.
+10. After it gets verified, click on `Subscribe to bot events`, add `message.channels` Bot User Event and click on `Save Changes`.
+11. Now go to your workspace, right click on the bot name in the sidebar, click `view app details`, then `add this app to a channel`.

+title: '🛠️ LangSmith'
+description: 'Integrate with Langsmith to debug and monitor your LLM app'
+---
+
+Embedchain now supports integration with [LangSmith](https://www.langchain.com/langsmith).
+
+To use langsmith, you need to do the following steps
+
+1. Have an account on langsmith and keep the environment variables in handy
+2. Set the environments variables in your app so that embedchain has context about it.
+3. Just use embedchain and everything will be logged to LangSmith, so that you can better test and monitor your application.
+
+Lets cover each step in detail.
+
+* First make sure that you a LangSmith account created and have all the necessary variables handy. LangSmith has a [good documentation](https://docs.smith.langchain.com/) on how to get started with their service.
+
+* Once you have the account setup, we will need the following environment variables
+
+```bash
+export LANGCHAIN_TRACING_V2=true
+export LANGCHAIN_ENDPOINT=https://api.smith.langchain.com
+export LANGCHAIN_API_KEY=<your-api-key>
+export LANGCHAIN_PROJECT=<your-project>  # if not specified, defaults to "default"
+```
+
+If you are using Python, you can use the following code to set environment variables
+
+```python
+import os
+
+os.environ['LANGCHAIN_TRACING_V2'] = 'true'
+os.environ['LANGCHAIN_ENDPOINT'] = 'https://api.smith.langchain.com'
+os.environ['LANGCHAIN_API_KEY'] = <your-api-key>
+os.environ['LANGCHAIN_PROJECT] = <your-project>
+```
+
+* Now create an app using embedchain and everything will be automatically visible in the LangSmith
+
+
+```python
+from embedchain import App
+
+app = App()
+app.add("https://en.wikipedia.org/wiki/Elon_Musk")
+app.query("How many companies did Elon found?")
+```
+
+* Now the entire log for this will be visible in langsmith.

+
+embedchain is a framework to easily create LLM powered bots over any dataset. embedchainjs is Javascript version of embedchain. If you want a python version, check out [embedchain-python](https://github.com/embedchain/embedchain)
+
+# 🤝 Let's Talk Embedchain!
+
+Schedule a [Feedback Session](https://cal.com/taranjeetio/ec) with Taranjeet, the founder, to discuss any issues, provide feedback, or explore improvements.
+
+# How it works
+
+It abstracts the entire process of loading dataset, chunking it, creating embeddings and then storing in vector database.
+
+You can add a single or multiple dataset using `.add` and `.addLocal` function and then use `.query` function to find an answer from the added datasets.
+
+If you want to create a Naval Ravikant bot which has 2 of his blog posts, as well as a question and answer pair you supply, all you need to do is add the links to the blog posts and the QnA pair and embedchain will create a bot for you.
+
+```javascript
+const dotenv = require("dotenv");
+dotenv.config();
+const { App } = require("embedchain");
+
+//Run the app commands inside an async function only
+async function testApp() {
+  const navalChatBot = await App();
+
+  // Embed Online Resources
+  await navalChatBot.add("web_page", "https://nav.al/feedback");
+  await navalChatBot.add("web_page", "https://nav.al/agi");
+  await navalChatBot.add(
+    "pdf_file",
+    "https://navalmanack.s3.amazonaws.com/Eric-Jorgenson_The-Almanack-of-Naval-Ravikant_Final.pdf"
+  );
+
+  // Embed Local Resources
+  await navalChatBot.addLocal("qna_pair", [
+    "Who is Naval Ravikant?",
+    "Naval Ravikant is an Indian-American entrepreneur and investor.",
+  ]);
+
+  const result = await navalChatBot.query(
+    "What unique capacity does Naval argue humans possess when it comes to understanding explanations or concepts?"
+  );
+  console.log(result);
+  // answer: Naval argues that humans possess the unique capacity to understand explanations or concepts to the maximum extent possible in this physical reality.
+}
+
+testApp();
+```
+
+# Getting Started
+
+## Installation
+
+- First make sure that you have the package installed. If not, then install it using `npm`
+
+```bash
+npm install embedchain && npm install -S openai@^3.3.0
+```
+
+- Currently, it is only compatible with openai 3.X, not the latest version 4.X. Please make sure to use the right version, otherwise you will see the `ChromaDB` error `TypeError: OpenAIApi.Configuration is not a constructor`
+
+- Make sure that dotenv package is installed and your `OPENAI_API_KEY` in a file called `.env` in the root folder. You can install dotenv by
+
+```js
+npm install dotenv
+```
+
+- Download and install Docker on your device by visiting [this link](https://www.docker.com/). You will need this to run Chroma vector database on your machine.
+
+- Run the following commands to setup Chroma container in Docker
+
+```bash
+git clone https://github.com/chroma-core/chroma.git
+cd chroma
+docker-compose up -d --build
+```
+
+- Once Chroma container has been set up, run it inside Docker
+
+## Usage
+
+- We use OpenAI's embedding model to create embeddings for chunks and ChatGPT API as LLM to get answer given the relevant docs. Make sure that you have an OpenAI account and an API key. If you have dont have an API key, you can create one by visiting [this link](https://platform.openai.com/account/api-keys).
+
+- Once you have the API key, set it in an environment variable called `OPENAI_API_KEY`
+
+```js
+// Set this inside your .env file
+OPENAI_API_KEY = "sk-xxxx";
+```
+
+- Load the environment variables inside your .js file using the following commands
+
+```js
+const dotenv = require("dotenv");
+dotenv.config();
+```
+
+- Next import the `App` class from embedchain and use `.add` function to add any dataset.
+- Now your app is created. You can use `.query` function to get the answer for any query.
+
+```js
+const dotenv = require("dotenv");
+dotenv.config();
+const { App } = require("embedchain");
+
+async function testApp() {
+  const navalChatBot = await App();
+
+  // Embed Online Resources
+  await navalChatBot.add("web_page", "https://nav.al/feedback");
+  await navalChatBot.add("web_page", "https://nav.al/agi");
+  await navalChatBot.add(
+    "pdf_file",
+    "https://navalmanack.s3.amazonaws.com/Eric-Jorgenson_The-Almanack-of-Naval-Ravikant_Final.pdf"
+  );
+
+  // Embed Local Resources
+  await navalChatBot.addLocal("qna_pair", [
+    "Who is Naval Ravikant?",
+    "Naval Ravikant is an Indian-American entrepreneur and investor.",
+  ]);
+
+  const result = await navalChatBot.query(
+    "What unique capacity does Naval argue humans possess when it comes to understanding explanations or concepts?"
+  );
+  console.log(result);
+  // answer: Naval argues that humans possess the unique capacity to understand explanations or concepts to the maximum extent possible in this physical reality.
+}
+
+testApp();
+```
+
+- If there is any other app instance in your script or app, you can change the import as
+
+```javascript
+const { App: EmbedChainApp } = require("embedchain");
+
+// or
+
+const { App: ECApp } = require("embedchain");
+```
+
+## Format supported
+
+We support the following formats:
+
+### PDF File
+
+To add any pdf file, use the data_type as `pdf_file`. Eg:
+
+```javascript
+await app.add("pdf_file", "a_valid_url_where_pdf_file_can_be_accessed");
+```
+
+### Web Page
+
+To add any web page, use the data_type as `web_page`. Eg:
+
+```javascript
+await app.add("web_page", "a_valid_web_page_url");
+```
+
+### QnA Pair
+
+To supply your own QnA pair, use the data_type as `qna_pair` and enter a tuple. Eg:
+
+```javascript
+await app.addLocal("qna_pair", ["Question", "Answer"]);
+```
+
+### More Formats coming soon
+
+- If you want to add any other format, please create an [issue](https://github.com/embedchain/embedchainjs/issues) and we will add it to the list of supported formats.
+
+## Testing
+
+Before you consume valueable tokens, you should make sure that the embedding you have done works and that it's receiving the correct document from the database.
+
+For this you can use the `dryRun` method.
+
+Following the example above, add this to your script:
+
+```js
+let result = await naval_chat_bot.dryRun("What unique capacity does Naval argue humans possess when it comes to understanding explanations or concepts?");console.log(result);
+
+'''
+Use the following pieces of context to answer the query at the end. If you don't know the answer, just say that you don't know, don't try to make up an answer.
+terms of the unseen. And I think that’s critical. That is what humans do uniquely that no other creature, no other computer, no other intelligence—biological or artificial—that we have ever encountered does. And not only do we do it uniquely, but if we were to meet an alien species that also had the power to generate these good explanations, there is no explanation that they could generate that we could not understand. We are maximally capable of understanding. There is no concept out there that is possible in this physical reality that a human being, given sufficient time and resources and
+Query: What unique capacity does Naval argue humans possess when it comes to understanding explanations or concepts?
+Helpful Answer:
+'''
+```
+
+_The embedding is confirmed to work as expected. It returns the right document, even if the question is asked slightly different. No prompt tokens have been consumed._
+
+**The dry run will still consume tokens to embed your query, but it is only ~1/15 of the prompt.**
+
+# How does it work?
+
+Creating a chat bot over any dataset needs the following steps to happen
+
+- load the data
+- create meaningful chunks
+- create embeddings for each chunk
+- store the chunks in vector database
+
+Whenever a user asks any query, following process happens to find the answer for the query
+
+- create the embedding for query
+- find similar documents for this query from vector database
+- pass similar documents as context to LLM to get the final answer.
+
+The process of loading the dataset and then querying involves multiple steps and each steps has nuances of it is own.
+
+- How should I chunk the data? What is a meaningful chunk size?
+- How should I create embeddings for each chunk? Which embedding model should I use?
+- How should I store the chunks in vector database? Which vector database should I use?
+- Should I store meta data along with the embeddings?
+- How should I find similar documents for a query? Which ranking model should I use?
+
+These questions may be trivial for some but for a lot of us, it needs research, experimentation and time to find out the accurate answers.
+
+embedchain is a framework which takes care of all these nuances and provides a simple interface to create bots over any dataset.
+
+In the first release, we are making it easier for anyone to get a chatbot over any dataset up and running in less than a minute. All you need to do is create an app instance, add the data sets using `.add` function and then use `.query` function to get the relevant answer.
