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.

📌Hey PH! I built PR Explainer because I was tired of reviewing PRs by staring at diffs and mentally reconstructing what happened. Most AI tools just throw the diff at an LLM — which leads to hallucinated file paths and vague explanations.
PR Explainer takes a different approach: a Rust-powered analysis engine builds a context graph of your changes before the LLM sees anything. It resolves dependencies, traces call sites, and classifies changes by severity — so the narration is grounded in real code, not guesswork.
The whole thing runs locally in VS Code. Your code goes directly to the LLM provider — never through our servers. Would love your feedback!

Can you export the narrated walkthrough as a shareable link for async code reviews with teammates who use different editors? Really cool approach to code reviews!

@mateuszjacni The generated tours will work on any VSCode based editor so creating an exportable bundle is trivial for those, can explore how I can make it work for other editors!
Thank you :-)

Hi Mateo,
Appreciate your review a lot!
You can configure your own model and provider for both the tour generation and voice! It includes 10 free tours for you to try at the moment.
I can do a better job documenting that maybe!
