PR Description Generator (AI)

Code

Paste a git diff and get back a structured pull request description: a title, a bulleted summary of what changed, and a test plan checklist, powered by GPT-4o mini

Paste a git diff and GPT-4o mini drafts the pull request description for you: a concise imperative title, a bulleted summary of what actually changed, and a test plan checklist a reviewer could follow line by line. This is a server-backed AI tool, not a browser-only utility, so the diff text is sent to OpenAI's API to generate the response, and it is a distinct sibling of the site's Commit Message Generator: that tool writes a short Conventional Commits message for the commit itself, while this one writes the longer, reviewer-facing document that goes in the PR body. It works from the diff alone, so a change with unclear intent can get a generic summary or test plan; the optional context field exists to nudge it with a ticket number or a sentence about why you made the change.

How to use PR Description Generator (AI)

  • 1.Paste the output of `git diff` or `git diff main...HEAD` to get a ready-to-paste PR description.
  • 2.Add optional context, like a ticket number or a short note about why you made the change, when the diff alone doesn't make the intent obvious.
  • 3.Copy the generated Markdown into your PR body, then review and check off each test plan item as you actually verify it.

Frequently asked questions

How is this different from the Commit Message Generator?
The Commit Message Generator writes a short Conventional Commits-style message for a single commit. This tool writes a longer, structured PR description meant for the pull request body itself: a title, a bulleted summary, and a test plan checklist for reviewers.
Does this run in my browser or on a server?
Generation calls GPT-4o mini on the server since it requires an LLM, so the diff text you paste is sent to OpenAI's API to generate the response.
How long can the diff be?
Up to 12,000 characters. For a much larger diff, paste just the most relevant hunks rather than the entire changeset.
Is the generated test plan guaranteed to be correct or complete?
No, it's inferred from the diff text alone with no access to your actual test suite or runtime behavior, so treat it as a starting checklist to verify and edit, not a guarantee of full coverage.
