DiffAtlas
Know if an AI-generated PR is worth reviewing
What it does
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.
Map TypeScript pull requests, surface sensitive and disconnected changes, and decide what to review or send back.
DiffAtlas maps every changed TypeScript file, flags sensitive authentication and route changes, and scores reviewability. You can review with confidence or send the work back. Follow the change down: map the full pull request, surface its review risks, then decide whether to review it or send it back. Turn a flat list of changed files into a dependency map. See the main change path, understand what depends on what, and keep context while you review. See reviewability, scope, cohesion, authentication changes, and route changes before opening a diff. Sensitive and disconnected work gets your attention first. Open the right diff directly from the map. If the pull request is too broad or mixes…from diffatlas.dev

Hi HN! We were frustrated with text diffs on GitHub PRs, so we made DiffLens (https://github.com/marketplace/difflens). DiffLens constructs an Abstract Syntax Tree for each file, and uses that semantic information to intelligently diff changes. Checkout the demo on our website (https://www.difflens.com). Getting started with DiffLens is easy! Simply install the app on your repositories. The next time you open a PR, DiffLens will automatically create a diff for your changes. If you review code, especially TypeScript, JavaScript or CSS, give DiffLens a try! We're…

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up. One…
