What is DiffSense?

DiffSense is a command-line tool that generates git commit messages using the native AFM 3B model on Apple Silicon. It runs entirely locally with zero latency, ensuring your code never leaves your machine. The tool analyzes your git diff and produces clear, context-aware commit messages in seconds—no internet connection required.

Who it's for

• Solo developers who want to speed up their git workflow without sacrificing privacy or control over their commit history
• Privacy-conscious teams that need to keep source code strictly on-device while still benefiting from AI-generated commit messages
• macOS power users running Apple Silicon who prefer local AI tools over cloud-dependent alternatives

Key features

🔓 Local & private on Apple Silicon

DiffSense turns your git diff into clear, privacy-friendly commit messages using the native AFM 3B model. Everything runs on your device, so your code stays completely private with no data sent to external servers.

⚙️ Customizable git message styles

Choose from Default, Minimal, or Verbose message styles, or define your own rules with BYO (Bring Your Own) templates. Every generated message remains editable before you commit, giving you full control over the final output.

⚡️ Fast diff algorithm

The tool handles any diff size with ease, processing changes instantly regardless of how many files you've modified. No waiting for cloud round-trips—just immediate results.

🦁 Powerful alias macros

Create custom aliases that prepend git add . or append git push to your workflow. This lets you chain multiple git operations into a single command, streamlining your entire commit process.

What stands out

"DiffSense turns your git diff into clear, privacy-friendly commit messages—no internet required."

This local-first approach is what truly sets DiffSense apart. While most AI commit tools rely on cloud APIs that expose your code, DiffSense keeps everything on your Apple Silicon device. The combination of zero latency, complete privacy, and customizable message styles makes it a practical choice for developers who want AI assistance without compromising security.

Worth checking out if…

You're a macOS developer using Apple Silicon who values code privacy and wants to automate commit message generation without relying on cloud services. DiffSense is especially useful if you work with sensitive codebases, prefer local AI models, or simply want a faster, more streamlined git workflow that keeps your data under your control.
