Review the turn
See the prompt beside everything that changed in an agent's last turn. Attribution survives rebases and squashes.
The native review desk for MacReview the work,
Review the work,
not just the diff.
Fettle keeps the code, the prompt, the screenshots, and your verdict in one place.
Open local changes, agent turns, clean branches, or pull requests without pushing first. Work through the evidence, leave precise feedback, and hand the review back with its context intact.
Mac only. Requires macOS 26 Tahoe or later on Apple silicon.
The diff tells you what changed. Fettle keeps why it changed close enough to judge.
One review loop
From first file to final verdict
Read the whole change
Inspect syntax-highlighted diffs, mark files reviewed, and catch marks that went stale after another edit.
Check what pixels did
Keep screenshots, visual test results, numbered markers, and notes beside the code that produced them.
Send back a verdict
Export an agent-ready review packet or post new comments to an existing GitHub pull request.
Works alone, better together
Pair it with Saggar when agents are doing the work.
Fettle reviews any local repository on its own. Saggar adds turn grouping and the prompt behind each change, so a review starts with intent instead of archaeology.
