I'm Ofer, head of developer relations at Vectara.

Some of us read a lot of articles on the web, like those on HN, and it seems useful to be able to search the contents of the text we read (using semantic search), or ask questions about it (ChatGPT style).

Sankofa is a new browser extension that allows you to index web pages you visit and search / ask questions about that content. We built it using Vectara's retrieval-augmented-generation (RAG) platform and hope this is useful to folks.

This is an initial release - we would love to hear any feedback and suggestions.

BTW, Sankofa which means "to retrieve" in the Twi language of Ghana.
