🤖 Apple's AI writes your message

The tool reads your changes and uses Apple's built-in intelligence to craft a clear, professional commit message right on your computer.

4
📝 You see your commit message

A clean, well-formatted message appears instantly, following the standard style developers expect.

What is saft?

Saft is a CLI tool that generates git commit messages using Apple's on-device language model. You stage your changes, run `saft`, and get a properly formatted commit message back. It enforces conventional commits style with imperative mood -- so you get "Fix authentication token refresh" instead of "Fixed" or "Adds new feature." The tool reads your diff and intelligently compresses it for larger changes using git's stat and unified formats, so even bigger PRs don't overwhelm the model. Everything runs locally on your Mac using Apple's FoundationModels framework.

Why is it gaining traction?

The appeal is obvious: no API keys, no subscriptions, no data leaving your machine. If you already have Apple Intelligence enabled, saft slots right into your workflow. It solves the "blank commit message" paralysis that derails focus, and the messages it produces follow real conventions -- not the generic "Update file" output you get from lesser tools. The roadmap shows ambition too, with multi-candidate selection and git hook integration planned.

Who should use this?

Mac developers who want AI-assisted commit messages without adding another API key to their secrets manager. Works especially well if you're already bought into Apple Intelligence. Small teams tired of bikeshedding over commit message wording will appreciate the consistent output. Not for Linux or Windows users, and probably too early for teams with strict tooling governance.

Verdict

It's a clever, focused tool with a real differentiator in the on-device AI approach. At 15 stars and requiring macOS 26.0, it's extremely early -- the credibility score of 0.85% reflects that maturity. Worth watching if you're on Apple Silicon, but hold off on production team rollouts until it sees more battle testing.
