About Notion QA
Notion QA is an open-source Python tool that enables natural language question-answering over Notion databases. Built with LangChain, it allows users to export their Notion data (in Markdown/CSV format), ingest it locally, and then query the database using a conversational CLI or a StreamLit web app. The repository includes example data from the Blendle Employee Handbook and provides step-by-step instructions for setting up and ingesting custom Notion exports. Users need an OpenAI API key to run the underlying language model. The project is licensed under MIT and has over 2,200 GitHub stars.

FAQ
How do I use Notion QA with my own Notion database?
Export your Notion page as Markdown/CSV (three dots > Export), move the .zip file into the repository, unzip it into Notion_DB folder, and run 'python ingest.py'. Then you can ask questions using 'python qa.py "your question"'.
Does Notion QA require an API key?
Yes, you need to set the OPENAI_API_KEY environment variable with a valid OpenAI API key to run the language model.
Can I deploy Notion QA as a web app?
Yes, the repository includes a StreamLit app (main.py) that can be deployed. You need to set OPENAI_API_KEY as a secret environment variable in StreamLit.
What format does the Notion export need to be in?
The export must be in Markdown & CSV format (select 'Markdown CSV' when exporting from Notion).
