Hi @Oscarr,
Initially, I created a google sheet + GPT Integration to help people ask questions using data on the spreadsheet with embeddings. Google Spreadsheet + GPT3 - #24 by songsofthespheres1
This work for simple use cases. But then some of the users needed a more robust solutions, they wanted a similar solution but with a lot more custom data. So I created this app to read thru multiple documents and create many embeddings ahead of time. When someone ask a question, the app will find the best embeddings to use and include only the necessary context in the prompt. This seems to be working very well for large custom datasets.
