PR Explainer (Beta) — Narrated Code Tours & Reviews

singhularity.prexplainer

PR Explainer analyzes your code structure before generating anything. It traces dependencies, reads call sites, and classifies changes so tours reference real files at verified line numbers — not hallucinated paths. Run a narrated walkthrough of any PR or uncommitted changes, get severity-graded code review findings with inline gutter markers, export it as an MP4 with captions, a selectable-text PDF, or a portable .prtour file that opens against your teammate's checkout — review findings travel with every export. Works with 11 languages and frameworks like React, Spring Boot, FastAPI, Django, and more.
