git-ai
https://gitai.run/
The project helps automatically save prompts and track AI-generated code. It is currently in the Preview development-testing stage. It's Git-native, storing authorship logs in JSON format within Git, tied to commits. Written in Rust (fast, cross-platform).

Uses "checkpoints" (git-ai checkpoint) before and after file changes by agents to mark authorship (human or AI). Commands include git-ai checkpoint for marking and git-ai blame <file> for viewing.

Can be integrated into Cursor and Claude Code.
