What is Commit Message Generator?

Commit Message Generator is a free AI coding assistant that turns a description of your code changes into a clean, conventional commit message in several formats. Each request is handed to a code-specialized model chosen for the task, returning working code, bug fixes, and explanations in any programming language in seconds. You paste and go, with no login and nothing to install, and the code you share is not retained once the session ends.

✦Paste code and go, no login, nothing to install
✦Code-specialized models are selected per request automatically
✦Your code is not retained after the session ends

Models: It routes across strong coding models including Llama, Gemini and Mistral families, picking the best available one per request. The exact model used is shown after every response.

See it in action

You have finished a tweak to the login screen and want a tidy message before you push.

What you type

changed the login form so it shows a spinner while the request is in flight and disabled the submit button, because people were double-clicking and creating two sessions

What you get

fix(auth): prevent duplicate sessions on login submit Disable the submit button and show a loading spinner while the sign-in request is in flight, so a second click cannot fire a second request before the first resolves. Alternative (short): fix: debounce login submit to stop double sessions

Tip: Conventional Commits reads the type and scope to auto-generate changelogs and version bumps, so a double-click guard belongs under fix, not feat. Mention the user-facing symptom in your description and the generated body will explain the why, which is the part reviewers actually read.

Use cases

What people use it for

Sum up a scattered afternoon of changes in a commit message your teammates can follow.

Match a new team's conventional-commit style without memorizing every type prefix.

Split one oversized change into a crisp subject line plus a body explaining why.

Who uses Commit Message Generator?

Open-source contributors

turning a messy set of changes into a Conventional Commits message that passes a project automated lint check

Busy developers

getting a clear message for a commit at the end of a long day when the wording just will not come

Team leads

modeling a consistent commit style for junior developers to copy across the repository history

How it works

1Paste your code or describe what you need built.
2A code-specialized model writes, fixes, or explains it.
3Copy the code out, or ask follow-ups to iterate on it.

Tips for the best results

Paste the actual diff rather than describing it when you can, since the tool writes a far more accurate subject when it can see exactly what changed.
Add the reason for the change in a sentence, such as the bug it fixes or the request it answers, so the message captures the why that a diff alone never shows.
Name the convention you follow, whether Conventional Commits, a ticket prefix or a plain style, so the message drops straight into your workflow.
Ask it to keep the subject under about fifty characters and in the imperative mood, matching git own convention and keeping the log readable.
Split unrelated changes into separate commits and generate a message for each, rather than one vague message that tries to cover everything at once.

FAQ

Frequently asked questions

What commit formats does it produce?

Several per request: a conventional commit with the right type prefix (feat, fix, chore, refactor), a plain imperative subject line, and a subject-plus-body version for changes that need explanation. Pick whichever suits your repository, or ask it to match a house style you show it.

Is it better to paste the diff or describe my changes?

The diff, when it's manageable, git diff output lets the message reflect what genuinely changed rather than what you remember changing. For sprawling changes, a description works, though it inherits your blind spots. A middle path: provide the diff --stat summary plus a sentence of intent.

How do I get the 'why' into the message, not just the 'what'?

Tell it the motivation, because a diff can't carry it: the ticket you're closing, the performance problem you measured, the incident that prompted the change. That reasoning belongs in the commit body, six months from now it's the part of the message that actually matters.

My subject lines always run too long, can it help?

Keeping the subject terse and pushing detail into the body is precisely what it's good at. The widely followed Git convention favors a short imperative subject, 'add retry to payment webhook', with elaboration below. If a subject can't come out short, that's often a hint the commit should be split.

Can it follow my team's own conventions, like ticket references?

Show it an example. Paste a couple of commits from your history (prefix style, ticket-number placement, capitalization quirks) and ask it to match them. Team conventions vary too much to guess, but they're easy to imitate from a sample, and the sample only needs providing once per session.

Is this commit message generator free with no account?

Yes, free with no sign-up, account or payment. Describe your changes or paste a diff and get a clean message back, as often as you need with nothing behind a login. It generates text only; you copy the message into your own git commit, so it never touches your repository.

Can it write a full commit body and footer, not just the subject?

Yes. Ask for a full message and you get a concise subject line, a body that explains the reasoning and any footer you need, such as a breaking-change note or an issue reference. For a tiny change a one-line subject is enough; for anything with context worth recording, request the body too.

Can it mark a breaking change in the commit?

Yes. Tell it the change breaks compatibility and it adds the Conventional Commits marker, an exclamation mark after the type and a BREAKING CHANGE footer describing what consumers must update. This matters because release tooling reads that footer to bump the major version and generate changelog entries automatically.

What are the usage limits?

Code tools are text tools, so they are unmetered during the current free launch phase, iterate on a bug or generate as many drafts as the work needs. A short per-minute limit guards against scripted abuse only. Paid plans with higher limits and priority model access are coming soon.
