How often do you stall at the commit prompt, cursor blinking, unsure how to describe the work you just finished? You know exactly what you changed, yet the message comes out as "fix stuff" or "updates" again. Multiply that by every commit, and your history turns into noise nobody can read.
The reviewer opening your pull request feels it too. A vague log hides the one line that mattered, and a release with a thin changelog leaves users guessing. You want a message that says what changed and why, in a shape your team already follows.
The AI Git Commit Message Generator takes that job off your plate. You paste a diff or a plain summary of the work, pick a convention, and it writes the commit message, and on request a pull request description or a changelog, ready to review and push.
Short answer: The AI Git Commit Message Generator is a free browser tool that turns a diff or a short summary into a clear commit message. It can follow Conventional Commits, and it also drafts pull request descriptions, changelogs, and release notes, so your history reads well and your reviewers see the point fast.
What is AI Git Commit Message Generator?
The AI Git Commit Message Generator is a writing assistant for your version history. You give it the substance of a change, either the raw diff or a few notes on what you did, and it returns a properly shaped message. Its native output is a Conventional Commits line with an optional body, but the Output Type dropdown lets the same input become a PR description, a README section, a changelog, or release notes.
It runs in the browser, it is free, and it needs no account. The draft lands in an output card you can copy, listen to, reuse as the seed for a related document, or download. Because it works only from what you paste, it stays honest to your change: it describes the work in front of it and shapes it to the convention you chose.
Conventional Commits ready
Pick the Conventional Commits convention and you get a type, an optional scope, and a tidy subject line by default.
One input, many documents
The Output Type dropdown turns the same diff into a commit, a PR description, a changelog, or release notes.
You set the detail
Length and the Detail Level slider decide whether you get a one line subject or a subject plus a full body.
Copy or export fast
Send the draft to DOC, TXT, or HTML, or copy it straight into your terminal or your PR box.
Why Use AI Git Commit Message Generator?
A good commit message is a note to the future. Six months on, someone runs a blame on a line and lands on your commit. A clear subject tells them why it exists in seconds; a lazy one sends them digging through the diff. The AI Git Commit Message Generator makes the clear version cheap to write, so you stop trading history quality for speed.
It also keeps a team consistent. When everyone leans on the same conventions, the log reads like one voice instead of ten. Set the Convention to Conventional Commits and the tool produces the type prefixes your changelog tooling can parse. Run the same change through the AI Git Commit Message Generator as a commit first, then switch Output Type to PR Description, and the reviewer gets the fuller story without you writing it twice.
Where it shines A big feature branch you are about to open for review. Paste the combined summary, set Output Type to PR Description and Include Sections on, and you get a structured writeup with what changed, why, and how to test, instead of a wall of raw diff.
How Does AI Git Commit Message Generator Work?
The flow is quick. You paste your diff, your changed files, or a plain note on the work into the prompt box at the top. Under it sits the AI model selector, so you can run the same change through MSB AI, OpenAI ChatGPT, Anthropic Claude AI, Google Gemini, or another engine and compare the wording. Open the advanced options accordion to set the Output Type, the Convention, and the rest, then press Generate.
The message appears in the output card with a live word count. Each result carries Copy, Listen, Reuse, and Download, plus export to DOC, TXT, or HTML. The activity history panel keeps the earlier drafts from your session, so you can generate a Conventional Commits line, then a matching changelog entry, and keep both side by side without losing either.
Here is the shape it produces for a real change, with the Conventional Commits convention on:
feat(auth): add password reset via email token
Users can now request a reset link that expires after thirty minutes.
Adds the ResetToken model and the /auth/reset endpoint.
BREAKING CHANGE: removes the legacy /auth/forgot route.The subject states the change, the body explains it, and the footer flags what breaks. Here is how the main controls change what comes back:
| What you set | What changes in the output |
|---|---|
| Output Type | Whether you get a commit, a PR description, a changelog, or release notes. |
| Convention | The format of the subject line and whether a type prefix appears. |
| Length | Whether you get a bare subject or a subject plus a full body. |
| Add Emojis | Whether a small icon is prepended to the subject or the line stays plain. |
Which Settings Shape The Commit Message?
The advanced options are where a generic line becomes your team's line. Set the Convention first, because it decides the whole subject format, then use Length and the Detail Level slider to control how much body you get. Every option is documented below.
| Option | What it controls | When to change it | Suggested starting point |
|---|---|---|---|
| Output Type | The document produced: Commit Message, PR Description, README, Changelog, or Release Notes. | Switch it when you need the fuller writeup, not just the commit. | Commit Message |
| Convention | The subject format: Conventional Commits, Plain, Detailed, Concise, or Team Standard. | Match it to what your repo and changelog tooling expect. | Conventional Commits |
| Tone / Detail | How formal and thorough the wording reads. | Raise it for a public release, lower it for an internal fix. | Standard |
| Length | Short subject only, Normal, or Detailed with a body. | Go Detailed when the change needs context. | Normal |
| Follow Convention | Whether the draft is held to the chosen convention. | Keep on so the type prefix and shape stay valid. | On |
| Include Sections | Adds headed sections for a PR or changelog. | Turn on for PR Description or Changelog output. | On for long output |
| Add Emojis | Prepends an icon to the subject line. | Turn on only if your team uses gitmoji style logs. | Off |
| Include Examples | Adds sample usage or a snippet in a README or notes. | Useful for release notes, noise in a plain commit. | Off |
| Detail Level | A one to one hundred dial for how much explanation you get. | Lower it for a terse log, raise it for a rich body. | Around fifty |
| Custom Instructions | Free text rules the draft must follow. | Name a scope list, a ticket format, or a style rule. | Leave blank at first |
What Does A Generated Message Look Like?
Say you paste a diff that adds retry logic to a payments client and fixes a null check. With the Convention set to Conventional Commits and Length on Detailed, the output card returns a subject, a body, and, because your notes mentioned a removed option, a breaking change footer. Switch Output Type to Changelog on the next pass and the same work becomes a dated entry grouped under Added and Fixed. Switch again to PR Description with Include Sections on, and you get a summary, a list of changes, and a test plan.
It writes from what you tell it The AI Git Commit Message Generator only knows the diff or summary you paste. If your notes leave out a breaking change or a migration step, the message will leave it out too. Read the draft against your actual change before you push.
How Do You Draft A Commit Step By Step?
A reliable pass looks like this:
- Stage the change and copy the diff, or write a two line summary of what you did and why.
- Paste it into the prompt box and pick the AI model you want.
- Set Output Type to Commit Message and Convention to Conventional Commits.
- Choose a Length, keep Follow Convention on, and press Generate.
- Read the subject and body against your real change, then edit any detail the notes missed.
- Copy the result into your commit, and reuse the same input for a matching PR description.
One honest limit The tool cannot see your repository, your issue tracker, or the commits around this one. It will not know a ticket number or a related change unless you paste it in. Add that context in Custom Instructions when it matters.
Who Gets The Most From It?
Solo developers use it to keep a side project's history readable. Team leads use it to hold a squad to one commit convention. Open source maintainers use it to turn a pile of merged pull requests into release notes people actually read. Anyone who has typed "wip" one too many times is the target reader.
- Developers who want a clean, greppable log without the friction.
- Reviewers who need a PR description that explains the change, not just the diff.
- Maintainers assembling a changelog or release notes at cut time.
- New team members learning the house style from consistent examples.
What Are The Pros And Cons?
Pros
- Fast: a shaped message in seconds, not a blank cursor.
- Conventional Commits, plus PR descriptions, changelogs, and release notes from one input.
- Consistent wording keeps a whole team's log readable.
- Free, in the browser, no account, with a choice of AI models.
Cons
- It only knows what you paste, so a thin summary makes a thin message.
- It cannot confirm a breaking change or a ticket number on its own.
- You still review and edit before you push.
What Commit Mistakes Should You Avoid?
Most weak results trace back to a thin input, not the tool. Work through this before you push:
- ✅ Paste the actual diff or a specific summary, not just the file name.
- ✅ Set the Convention your repo already uses, so the log stays consistent.
- ✅ Flag any breaking change or migration in your notes so the footer is right.
- ✅ Keep one commit to one logical change, and generate a message per change.
- ✅ Read the subject against the diff before you accept it.
How Does It Compare To Writing Commits By Hand?
| Aspect | AI Git Commit Message Generator | Writing by hand |
|---|---|---|
| Speed | A shaped message in seconds | A blank line and a pause |
| Convention | Enforced by the dropdown | Only if you remember it |
| Reuse | Same input becomes a PR or changelog | Written again each time |
| Accuracy | Only as good as your summary | Only as good as your memory |

Frequently Asked Questions
Does it produce Conventional Commits format?
Yes. Set the Convention dropdown to Conventional Commits and the AI Git Commit Message Generator returns a type, an optional scope, a concise subject, and a footer for breaking changes when your notes call for one.
Can I paste a raw git diff instead of writing a summary?
You can. Paste the diff straight into the prompt box and the tool reads the changes to draft the message. A short line of intent alongside the diff usually sharpens the result.
Is there any charge or account needed to use it?
No. The AI Git Commit Message Generator runs in the browser for free, with no sign up and no card. Generate as many messages as you like and switch AI models whenever you want.
Will it flag a breaking change automatically?
Only if your input mentions it. The tool writes from what you paste, so if the diff or summary does not signal that something breaks, the message will not either. Call it out in your notes.
Can the same change become a changelog or release notes?
Yes. Keep the input and change Output Type to Changelog or Release Notes. The activity history keeps each draft, so you can generate the commit and the changelog entry from one session.
Does it work for languages other than English source code?
The message text is English by default. Your code and diff can be in any language, since the tool reads the change and describes it. Use Custom Instructions if you need a particular wording style.
