Git Commit Message AI, by kosmoray2207 (雷可扬), is a Chrome extension that helps developers produce standardized Git commit messages without external services. It converts a Git diff pasted from the clipboard into a Conventional Commits style message, reducing manual formatting and editing. The extension runs entirely in the browser using vanilla JavaScript, keeps an approximately 6 KiB footprint, and targets developers who need private, consistent commit history in individual or small-team workflows.

What is Git Commit Message AI used for?

The extension automates commit message creation from a clipboard diff. You paste a Git diff from your clipboard and the tool returns a formatted Conventional Commits message, so writers do not assemble type/scope/description manually. The app is built as a Chrome add-on and therefore integrates into Chromium-based browsing environments, aiming at people who draft commits as part of a web-based workflow.

How lightweight and responsive is the extension in daily use?

Small install size and local logic keep latency minimal. The extension’s published footprint is about 6 KiB and it uses vanilla JavaScript for processing, which implies a very small download and quick start. Because it performs work in the browser, generation happens without waiting for network requests, so message output is effectively instant after pasting a diff.

How does the extension treat privacy and code data?

Processing happens on-device with a declared no-data policy. The developer’s privacy statement says no user data is collected or sold, and the extension uses no external API calls, so clipboard diffs are analyzed within the browser. The developer identity and a clean privacy record provide an explicit privacy posture suitable for repositories with sensitive code.

Who benefits from this tool and what are the trade-offs?

It fits developers who want consistent, on-device commit messages. The extension is tailored to engineers who accept a clipboard-based workflow and Conventional Commits formatting. Trade-offs include a lack of announced editor plugins or cloud AI context and support limited to Chromium-based browsers. Practical usage steps include:

• copy a staged diff to the clipboard
• open the extension and paste
• copy the generated Conventional Commit message into your VCS client

A pragmatic, privacy-first helper for developers focused on commit hygiene

Choose this extension if you prioritize keeping diffs local and enforcing a commit convention across a team, and use the paste-from-clipboard workflow to keep message scope tight. A practical tip: generate messages from staged-file diffs to match commit scope. The extension is a practical option for developers who want consistent, on-device commit message generation, though it trades deeper cloud-based context or editor integrations.
