DiffSense
Local AI git commit generator for Apple Silicon
Visit website →About
DiffSense generates git commit messages locally on Apple Silicon using Apple's on-device AFM 3B model. It reads the staged diff and writes a commit message with no network call, so the code never leaves the machine and there is no per-use cost or latency.
It supports customisable message styles and alias macros for common patterns, fitting into a developer's existing git workflow.
It is aimed at developers on Mac who want AI-written commit messages but do not want to send diffs to a cloud service, whether for privacy, working offline, or avoiding another subscription.

Why we picked it
DiffSense made the cut for running entirely on-device with Apple's own AFM model — no network call means no per-use cost and code that genuinely never leaves the machine, worth naming for anyone who's never trusted a cloud commit-message generator with a private repo.
