GitHub shows a pull request as a linear list of diffs. But code doesn’t change linearly. I learned that the hard way, after hours of jumping from file to file, I’d lose the thread and still miss a route, an auth setting, or the connection that made the change risky. AI-generated PRs only made it worse. So I built DiffAtlas. It turns a TypeScript PR into a map of the change, helping you see its intent, focus review where it matters, and move faster with confidence.
