So, I made this tool where you can generate documentation for any GitHub repo. Since all files get embedded/summarized anyways, I'm storing this info in a database and you get a RAG-chat for the entire codebase for free!
To try it out, simply open https://www.givemedocs.com/<owner>/<repo> or replace the "github.com" on any GitHub page with "givemedocs.com".
And, please don't overdo it. There is some rate limiting in place but if you trigger my API key's usage limit, the service will stop working for everyone, which would be a bummer.
Enjoy!
