Oh, nifty! This is more a demo of a PDF search engine that you could (in parts 1 thru x of the series) deploy to an intranet (for internal knowledge search) or internet (for general search), rather than a collaborative tool.

For handwritten/math symbols, I'm sure it wouldn't be too hard to integrate something. The Jina Flow [0] concept makes integrating new Executors [1] pretty easy.

I LOVE the testimonials on the site btw!

Mathpix snip for pdf to Latex is excellent. Thank you for the free tier. It is helpful transcribing pdf math homework sets to use in the solution document without bugging the instructor for their source.
