This repository contains an implementation of a backend for the Notiondipity browser extension. It fulfills the following functions:
- It acts as a proxy for calling the Notion API when needed. Notion API can't be used directly from a browser because it doesn't support cross-site scripting.
- It uses OpenAI's APIs to create Notion page embeddings and to generate project ideas.
- It stores embeddings, Notion page titles and encrypted contents in a Postgres database. Getting this data from a database is much faster than calling Notion API
The backend exposes a REST-like API with following endpoints. Except
for the /v1/token endpoint, all API requests need to have an
Authorization containing Bearer {JWT}.
Expects an OAuth2 code and a redirect URL. Returns a JWT that is then used to authenticate all other API requests. The JWT contains a unique Notion user ID and a Notion API access token.
Checks if user's Notion data have been already processed and can be used to recommend similar pages, generate ideas or perform other actions
Refreshes Notion page embeddings, contents and titles for a given user. Since this is a computationaly intensive operation each user can only perform it once every 30 minutes.
Generates project ideas from provided content and the content of up to 2 most similar Notion pages. This usually takes several tens of seconds.
Returns a list of pages most similar to provided content. Can be used both to perform semantic search and to recommend pages similar to the one currently open.
