What are Conventional Commits?

Conventional Commits is a widely adopted convention for writing commit messages in a structured, machine-readable way. The format is type(scope): description — for example, feat(auth): add password reset. This makes history easier to scan and enables automated changelogs and semantic versioning.

Commit types

feat — a new feature
fix — a bug fix
docs — documentation only
style — formatting, no code change
refactor — code change that neither fixes a bug nor adds a feature
perf — a performance improvement
test — adding or fixing tests
chore — build process, tooling, dependencies

How to use this tool

You can either describe your change in plain English ("added dark mode toggle") or paste the raw output of git diff. The AI infers the right type and scope and writes a concise subject line, plus a bullet body when the change is non-trivial.

Tips for good commit messages

Use the imperative mood: "add", not "added" or "adds".
Keep the subject line under ~72 characters.
Explain the "why" in the body when it isn't obvious.
One logical change per commit.
