Show HN: Give your files an undo button (useundo.co)

It hooks into the filesystem directly. Undo runs as a background watcher on a folder/project, sees file changes regardless of which app made them, and snapshots local history into ~/.undo/.

So it’s not wrapping specific apps like Cursor, VS Code, etc. Any editor or tool that writes files is covered.

It's also OSS, you can check it out.

It's one of the things on my to-do. Is that a pain point for you?
