Question 1

What is PullRequestAI?

Accepted Answer

A free tool that converts a git diff into a structured pull request description in under 50 milliseconds, entirely in your browser.

Question 2

Does it send my code to a server?

Accepted Answer

No. The diff is processed entirely in your browser using JavaScript. Nothing is uploaded.

Question 3

Is it free?

Accepted Answer

Yes, completely free. No signup, no API key, no rate limits.

Question 4

What format does it generate?

Accepted Answer

A Markdown PR description with a Conventional Commits title, summary, file change list, highlights, testing notes, and stats.

Question 5

How does it work without an LLM?

Accepted Answer

It uses a deterministic diff parser plus a heuristic classifier that detects feat/fix/refactor/docs/style/ci/chore from path and content signals. Predictable, instant, and free.

Question 6

What input format is supported?

Accepted Answer

Standard unified diff format — the output of git diff, git diff --cached, or git diff main...your-branch.
