⚠ Unlike most of the site, this tool sends your input to an AI model to work. It tells you exactly what is sent and why — see the tool and the privacy page.

An AI commit message generator reads a git diff and writes a clean Conventional Commit message so you don’t have to.

What’s sent

This is an AI tool: your diff is sent to Cloudflare Workers AI to summarize, processed to produce the message, and not stored. It’s labeled [USES_AI]. Don’t paste secrets or code you can’t share with a model; otherwise paste away.

Review before committing — treat the output as a strong draft.

Frequently asked questions

What do I paste?

The output of git diff (or git diff --staged for what you're about to commit). The tool reads the changes and writes a Conventional Commit message — a subject line like "feat(api): add rate limiting" plus a short body when the change warrants it.

Does my code/diff leave my browser?

Yes — this is an AI tool, so the diff is sent to Cloudflare Workers AI to summarize it. It is processed to produce the message and not stored by this tool. Don't paste secrets or proprietary code you're not comfortable sending to a model; for everything else it's fine. (Most tools on this site are 100% in-browser; this one is labeled because it uses a model.)

What format does it produce?

Conventional Commits: "type(scope): summary" with type from feat/fix/docs/style/refactor/perf/test/build/ci/chore, an imperative subject under ~72 characters, and an optional bullet-point body for non-trivial changes.

Is it free?

Yes — no signup, no cost to you. Runs on Cloudflare's free Workers AI tier with a quick bot check to prevent abuse. Large diffs are truncated to keep it fast.
