What it does
PR Explainer turns pull requests into narrated walkthroughs you can listen to. Open any PR in VS Code, hit "Explain PR," and a voice walks you through each change while the relevant code highlights in your editor. Pause, rewind, skip — like a podcast for code reviews. It understands your codebase before explaining it — so every explanation references real files and real line numbers. Works with 11 languages. Export tours as MP4 videos with captions. Free to use (or managed!), runs locally.
Narrated walkthroughs and code reviews for pull requests. Highlights the code, talks you through the changes, and flags issues with severity-graded findings. Like pair programming with the person who wrote it.
PR Explainer doesn't just throw your diff at an LLM and hope for the best. It builds a context graph that resolves dependencies, traces call sites, and classifies changes by severity, so every tour and review references real code at verified line numbers. The narrated walkthroughs explain what changed; the review findings flag what's wrong. Both read actual code, not a few lines of a patch. Any PR, any size. Run "Explain PR" from the command palette. A voice walks you through each change while the relevant lines light up. Pause, skip, or rewind. See severity-graded findings inline while you listen. Actually understand what you're approving. Export as video for the rest of the team. The…from prexplainer.com

A GitHub Action that quizzes you on a pull request2025 · github.com · ▲94A little idea I got from playing with AI SWE Agents. Can AI help make sure we understand the code that our AIs write? PR Quiz uses AI to generate a quiz from a pull request and blocks you from merging until the quiz is passed. You can configure various options like the LLM model to use, max number of attempts to pass the quiz or min diff size to generate a quiz for. I found that the reasoning models, while more expensive, generated better questions from my limited testing. Privacy: This GitHub Action runs a local webserver and uses ngrok to serve the quiz through a temporary url. Your code…
