Show HN: What % of your commits were written by AI?

Hi HN, I've been using Claude Code etc. for nearly all my work lately, and I wanted to see how many of my commits it was actually co-authoring. So I made this little tool to visualize my usage. You log in with Github (read-only), it scans your commits from the last year, and visualizes how many came from Claude, Cursor, or any tool that adds Co-Authored-By trailer to the commit message. Caveat: not all tools add this trailer, so this doesn't include e.g. Codex. Still, hope you find it interesting!
