Why every edit is a diff

Hearth never rewrites a file behind your back. Everything is a diff you can read, reject or undo.

Product

There is a version of an agent that just changes your files and tells you it is done. We did not want to build that one.

Reading beats trusting

A diff is the smallest thing that shows what changed. You already know how to read one, and so does your reviewer.

Undo is one key

Press esc and the last edit is undone. It is stored as a normal change in your version history, so nothing is lost.
