DiffSense
Free CLI that turns your staged git diff into a commit message using Apple Intelligence, locally on Apple Silicon Macs.
DiffSense is worth the one-line install if you're on an Apple Silicon Mac and you write a lot of commits. The Local AI backend runs Apple Intelligence on-device, so your diff never leaves the laptop — that is the feature that separates it from cloud commit helpers. Style presets (default, minimal, verbose, BYO rules) and the `--nopopup` flag make it scriptable rather than just clever. The structural limits are real: it's a terminal-only tool requiring Apple Silicon, and if you switch to the Private Cloud Compute or ChatGPT backend you've given up the privacy reason to pick it. On Windows or Linux, look elsewhere — a cloud-based helper or a local model you run yourself.

Skip DiffSense if you're not on an Apple Silicon Mac, or if you need a GUI for reviewing diffs rather than a terminal command.
DiffSense is free to install and use, with the Local AI backend riding on Apple Intelligence already present on your Apple Silicon Mac — so there's no per-seat or per-message meter to fit to a team size. Compared with paid cloud commit-message services, the cost difference is straightforward: nothing to budget, which suits solo developers and small teams rather than organizations looking to buy support or management features.
In short
DiffSense — Free CLI that turns your staged git diff into a commit message using Apple Intelligence, locally on Apple Silicon Macs. Best for Developers on Apple Silicon Macs who commit often, Solo developers and indie hackers who want free tooling, Teams working on proprietary code that can't be sent to cloud AI. Free to use.
What is DiffSense?
DiffSense — Free CLI that turns your staged git diff into a commit message using Apple Intelligence, locally on Apple Silicon Macs. Best for Developers on Apple Silicon Macs who commit often, Solo developers and indie hackers who want free tooling, Teams working on proprietary code that can't be sent to cloud AI. Free to use.
DiffSense is a command-line utility that writes your git commit messages for you. You stage your changes with `git add`, run `diffsense`, and it reads the diff and proposes a message — the homepage example turns a two-file change into "Add user authentication validation". You can edit the message in a popup before committing, or pass `--nopopup` to skip the review step when you're scripting it or running it inside an AI agent. Message style is configurable: default, minimal, verbose, or your own rules. The default backend is Local AI running on Apple Silicon via Apple Intelligence, so the diff stays on the machine — the reason the vendor leads with "privacy-friendly". Two other backends, Private Cloud Compute and ChatGPT, are offered for comparison or heavier lifting, and those do move the diff off the device. Install is a single curl pipe into bash from the project's GitHub Pages site. It is CLI-only, free to use, and specifically an Apple Silicon play: the local-model story is the whole pitch.

Models under the hood
as of 2026-10-23
Limitations
- DiffSense requires an Apple Silicon Mac and depends on Apple Intelligence for its Local AI backend, so Intel Macs, Windows and Linux are unsupported.
- It is a command-line tool with no desktop or web app — no visual diff browser, no history view.
- The homepage names three backends (Local AI, Private Cloud Compute, ChatGPT) but does not publish model versions or sizes for any of them, and only the Local backend keeps the diff on your machine; the other two send it off-device.
- There is no team management, centralized configuration, or audit trail.
- The project site shows zero downloads, stars and forks, so it is an early-stage tool without a broad user base to lean on.

Weighted by the 28 posts each of 2 sources contributed.
- +Free and unlimited—no subscriptions or API costs for local generation.
- +Code stays on-device in Local mode, addressing privacy concerns for sensitive work.
- +Zero-latency generation leverages Apple Silicon hardware users already own.
- +Simple curl install and one-command usage inside any git repo.
- +Customizable message styles (default, minimal, verbose, or custom rules).
- −Exclusively for Apple Silicon Macs—no Linux, Windows, or Intel support.
- −Small on-device model may struggle with large or complex diffs, per user questions.
- −No evidence of long-term support, updates, or community troubleshooting.
- −CLI-only interface may not fit developers who prefer GUI tools.
- −No IDE or editor integrations announced, limiting workflow fit.

GeneratedReal-world workflow fit
Concrete scenarios for the personas DiffSense actually fits — and what changes day-one when you adopt it.
You finish a change, run `git add .` and type `diffsense`. A popup shows a drafted message; you tweak a word and confirm the commit.
Outcome: You stop agonizing over commit phrasing and keep messages consistent without leaving the terminal.
You keep DiffSense on the Local AI backend so each staged diff is processed by Apple Intelligence on the machine rather than sent to a cloud API.
Outcome: You get AI-written commit messages while the diff stays on-device.
You call `diffsense --nopopup` from a script or agent so commit messages are generated without a human confirming a popup each time.
Outcome: Unattended commit generation that fits into existing automation.
Use cases
- Generate a commit message from staged changes with one `diffsense` command
- Run commit generation unattended in scripts or AI agents using --nopopup
- Keep proprietary diffs on-device by staying on the Local AI backend
- Chain git add, commit and push into one alias with DiffSense macros
- Enforce a consistent commit style across your repos with BYO rules
- Speed up commits on large diffs thanks to the fast diff algorithm
Setup time & first value
How long it actually takes to get something useful out of DiffSense — broken out by persona, not the marketing-page minute.
Setup is one command: paste the curl install line from the project site into Terminal, then run `diffsense` inside any git repo after staging changes. Expect a couple of minutes to first generated message, plus a little longer if you want to write your own style rules or set up alias macros.
Switching to or from DiffSense
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From writing messages by hand: stage with `git add`, run `diffsense`, edit the popup, commit
- →From a cloud commit-message tool: switch to the Local AI backend to keep diffs on-device
- ↗To a GUI git client with AI commit support: your repo and history are unchanged, so you just stop invoking the CLI
