DiffSense
Free, private AI commit message generator for Apple Silicon Macs.
If you own an Apple Silicon Mac and want free, unlimited, private commit message generation, DiffSense is a no-brainer. It runs locally with Apple's AFM 3B model, so your code never leaves your machine. But it's CLI-only and won't run on Intel or other OSes. For a similar local experience on Windows/Linux, consider alternatives like 'commitgpt' (open-source) or 'gptcommit'.

About DiffSense
DiffSense is a privacy-first AI tool that generates commit messages from git diffs entirely on your Apple Silicon Mac. It runs locally using Apple's AFM 3B model, so no code ever leaves your machine—perfect for solo developers, privacy-conscious teams, and open-source contributors who need speed without subscription costs. Operating from the command line, you install it with a single curl script and run 'diffsense' in any git repo to get an instant, context-aware commit message. You can customize the style (default, minimal, verbose, or bring-your-own rules), edit the message in a popup before committing, or skip the popup with '--nopopup' for CI/CD pipelines. DiffSense also supports multiple AI backends (Local, Private Cloud Compute, ChatGPT) and alias macros to combine add/commit/push. Its key limitation: Apple Silicon exclusivity means Intel Mac, Windows, and Linux users are out of luck. Compared to cloud-based alternatives like GitHub Copilot or GitKraken, DiffSense wins on zero cost and complete data privacy, but trades off GUI convenience and cross-platform support.
Behind the Verdict
DiffSense positions itself as a zero-cost, privacy-first commit message generator tailored specifically for Apple Silicon Macs. The core advantage is that everything runs on-device using Apple's AFM 3B model, meaning your source code never leaves your machine—a compelling feature for developers handling proprietary or sensitive code. The tool is a command-line utility that you install via a simple curl script, and it integrates directly into your git workflow: after staging changes, you run 'diffsense' and it instantly produces a context-aware commit message based on the diff. You can choose from default, minimal, verbose, or your own custom rules, and you have the option to edit the message in a popup before committing, or bypass it with '--nopopup' for CI/CD pipelines. Additionally, DiffSense supports multiple AI backends—Local AI, Private Cloud Compute, and ChatGPT—and alias macros that let you combine git add and commit/push into a single command. These features make it particularly handy for solo developers and small teams that value speed and privacy over a graphical interface. However, the tool is not without trade-offs. It is exclusively for Apple Silicon; Intel Macs, Windows, and Linux are not supported, which narrows its audience. The command-line-only interface might deter users who prefer GUI tools, and if you need team-level audit trails or centralized management, this won't satisfy you. The local model is fixed to Apple's AFM 3B, though options like Private Cloud Compute and ChatGPT are available as alternatives. In essence, DiffSense is a practical, no-cost solution for privacy-conscious developers on Apple Silicon who want to streamline their commit workflow without sending code to the cloud. If you fall outside that profile, you'd be better served by cross-platform tools like commitgpt or gptcommit.

You need to automate commit messages in a pipeline where no interactive popup is possible.
Outcome: Use `diffsense --nopopup` to generate and accept the message non-interactively, speeding up automation.
Your team deals with proprietary code that cannot be sent to cloud AI.
Outcome: DiffSense runs locally on each Mac, ensuring no code leaves the device while still providing AI suggestions.
Use Cases
- Generate a commit message from staged changes with one command
- Automate commit messages in CI/CD pipelines using --nopopup
- Keep code private while still benefiting from AI suggestions
