🔀 PullRequestAI

The free AI pull request description generator developers actually use

PullRequestAI turns any git diff into a clean, structured Markdown pull request description in seconds. No signup. No API key required. No "sign in with GitHub" dance. Paste a diff, hit Generate, copy the result into your PR.

Whether you're shipping a hotfix at 2am, opening your tenth PR of the day, or trying to get a code review approved before standup — writing PR descriptions is the part of the job nobody enjoys. We built this to delete that friction.

How the git diff to PR description converter works

1. Run git diff main...your-branch in your terminal (or use git diff --cached for staged changes).
2. Paste the unified diff into the box above.
3. Click Generate. Our AI analyses the changes, classifies the intent (feat / fix / refactor / docs / chore / perf / test / ci / style), and writes a description.
4. Copy the Markdown and paste it into GitHub, GitLab, Bitbucket, or Azure DevOps.

What's in every generated PR description

• Conventional Commits title — imperative mood, under 72 characters, correctly typed (feat, fix, refactor, etc.)
• Summary — a 2-4 sentence explanation of why the change exists, not just what changed
• Changes list — grouped by intent rather than by file path, so reviewers see logical units of work
• Risk & testing notes — surfaces breaking changes, security implications, and edge cases worth flagging
• Reviewer focus — 1-3 specific suggestions for where the reviewer should pay attention

Why developers prefer this to writing PR descriptions by hand

The average developer spends 15-30 minutes per pull request writing a description that reviewers will skim in 20 seconds. Multiply that across a team of 10 engineers shipping 5 PRs each per week, and you're burning ~25 hours of senior engineering time every week on a task that delivers no business value.

Worse, the descriptions usually suck. Half of them are "updates the auth flow" with no context. The other half are walls of text generated by your IDE that no one reads. PullRequestAI fixes both problems: descriptions are short, structured, and surface the things reviewers actually need to know — risk, testing, and where to focus.

Free tier vs Pro

The free hosted tier uses GPT-4o-mini and is rate-limited to 20 requests per hour and 100 per day per IP. That's enough for a typical solo dev.

The $9/month Pro tier upgrades you to GPT-4o (smarter summaries, better risk detection), 200 requests per hour, 500 per day, and priority hosting. Buy a license once, paste it in, and you're set — no account needed. Cancel any time. Upgrade to Pro →

Conventional Commits, automatically

Every generated title follows the Conventional Commits specification, the same standard used by Angular, Lerna, semantic-release, and most modern monorepos. The classifier looks at file paths, change patterns, and content signals to pick the right type:

• feat — new user-facing functionality
• fix — bug fix
• refactor — code restructure with no behaviour change
• perf — performance improvement
• docs — documentation only
• test — adding or fixing tests
• style — formatting / whitespace
• ci — CI/CD configuration
• chore — dependency updates and maintenance

Privacy and data handling

In Pro mode (BYO key), your diff goes from your browser straight to OpenAI or Anthropic using your own API key. We never see it.

In the free hosted tier, your diff is sent to our server (a single DigitalOcean droplet), forwarded to OpenAI, and discarded. We don't log diffs, we don't train on them, we don't sell them. Standard request logs (IP, timestamp) are kept for 7 days for rate-limiting purposes only.
