We release an open source version of Andrej Karparthy's open knowledge base, and we scale it to support long PDFs with Pageindex. Any feedback is welcome to help us improve this project!

So many Karparthy's Knowledge base projects. In the README.md would it be worth it to compare with others? (competition)

As a user I don't really want to go thru 30 of similar projects...

Hi, thanks for the feedback. Our biggest differentiation is that OpenKB can handle long PDFs and images—something that isn’t trivial or easily “vibe-coded.” We will try to find some ways to compare with other projects! Thanks for the valuable feedback!
