Decision brief
DataChad lets you ask questions about various data sources using embeddings, vector databases like Activeloop, and langchain.
Good fit when
- When you need to integrate multiple file types into a conversational interface leveraging langchains and vector databases.
- For projects requiring local storage of chat history akin to ChatGPT interactions.
Avoid when
- If your project strictly requires data processing or embeddings through technologies other than OpenAI or HuggingFace, as DataChad is tightly integrated with these.
- When full UI customization is needed; currently tied to Streamlit, with decoupling work in progress.

DataChad V3🤖
This is an app that let's you ask questions about any data source by leveraging embeddings, vector databases, large language models and last but not least langchains
How does it work?
- Upload any
file(s)or enter anypathorurlto create Knowledge Bases which can contain multiple files of any type, format and content and create Smart FAQs which are lists of curated numbered Q&As. - The data source or files are loaded and splitted into text document chunks
- The text document chunks are embedded using openai or huggingface embeddings
- The embeddings are stored as a vector dataset to activeloop's database hub
- A langchain is created consisting of a custom selection of an LLM model (
gpt-3.5-turboby default), multiple vector store as knowledge bases and a single special smart FAQ vector store - When asking questions to the app, the chain embeds the input prompt and does a similarity search in in the provided vector stores and uses the best results as context for the LLM to generate an appropriate response
- Finally the chat history is cached locally to enable a ChatGPT like Q&A conversation
Good to know
- The app only runs on
py>=3.10! - To run locally or deploy somewhere, execute
cp .env.template .envand set credentials in the newly created.envfile. Other options are manually setting of system environment variables, or storing them into.streamlit/secrets.tomlwhen hosted via streamlit. - If you have credentials set like explained above, you can just hit
submitin the authentication without reentering your credentials in the app. - If you run the app consider modifying the configuration in
datachad/backend/constants.py, e.g enabling advanced options - Your data won't load? Feel free to open an Issue or PR and contribute!
- Use previous releases like V1 or V2 for original functionality and UI
How does it look like?
TODO LIST
If you like to contribute, feel free to grab any task
- Refactor utils, especially the loaders
- Add option to choose model and embeddings
- Enable fully local / private mode
- Add option to upload multiple files to a single dataset
- Decouple datachad modules from streamlit
- remove all local mode and other V1 stuff
- Load existing knowledge bases
- Delete existing knowledge bases
- Enable streaming responses
- Show retrieved context
- Refactor UI
- Introduce smart FAQs
- Exchange downloaded file storage with tempfile
- Add user creation and login
- Add chat history per user
- Make all I/O asynchronous
- Implement FastAPI routes and backend app
- Implement a proper frontend (react or whatever)
- containerize the app
