Show HN: Generate beautiful documentation from any GitHub repository using AI

GitSummarize is an open-source devtool that I made this weekend.

Given any public GitHub repository it generates high-quality documentation from the codebase using Gemini 2.5 Pro.

Pro Tip: You can replace "hub" with "summarize" in any repository URL to access its documentation.

I created this because there was a steep learning curve to understanding some of the open-source codebases out there while getting started with contributing. Having detailed documentation would be immensely helpful in those situations.

This project was heavily inspired by GitIngest and GitDiagram so make sure to check those out as well!

Hopefully this tool can help you and feedback is always welcome!
