I need this so much, someone please build it ASAP. This would be so useful!

Working on it https://ont.fyi

The approach is not to capture all pages you view, rather you can add the pages etc you want in order to reduce the amount of noise/rubbish. It constructs a knowledge graph from these documents, and then a graph rag approach ontop to enable chat.

The core graph is based on wikidata, you can have your graphs either private or public if so they are published like those you can see on the site now.

Lots to do, but making ing good progress, if this sounds like something you might want to use please sign up.
