PR Docent

Guided, narrated review tours on top of GitHub pull request diffs.

PR Docent takes you on a tour of a GitHub pull request, right on the Files changed page. A large pull request is a long list of files in alphabetical order. PR Docent breaks it into chapters and walks through the files and lines in the order to read them: it scrolls to each step, frames the lines, fades the rest of the diff, and reads out what to look at. • Steps marked Key, Skim or Skippable, and a button that jumps straight to the next key step • Narration with your browser's built-in voices, pointing at the lines each sentence talks about • Review points: what to check at each step • Comment on a step's lines with GitHub's own comment form, drafted with the review point • "Done, next" marks each file Viewed on GitHub as the tour finishes it • Files the tour doesn't cover, so nothing is missed by trusting it • Shorts: a 30–45 second explanation in pictures for teammates who won't read the code, played right on the page • Keyboard shortcuts (Alt + arrows, Alt + P, Alt + V) • English and Korean Where tours come from • GitHub Actions: add one workflow and Claude Code writes a tour (and a short) for every pull request and posts it as a comment. The extension loads it automatically, with your own GitHub session, so private repositories work too. • Your computer: run `npx pr-docent install` once, then click "Create a tour with local Claude Code" in the panel. It uses your own Claude Code and subscription, with no API key. Your own guidelines for these tours can be set in PR Docent's settings. Try it on the demo pull request: https://github.com/thomas783/pr-docent/pull/22/changes PR Docent doesn't collect or sell your data; tours are kept in Chrome on your computer. The only thing sent to the developer is feedback you choose to send from the toolbar popup, which becomes a public GitHub issue. Setup and source: https://github.com/thomas783/pr-docent
