What is WhatTheDiff?
What The Diff is an AI‑powered assistant for pull requests that automatically writes descriptions, sends summarized notifications, and generates changelogs. It integrates with GitHub and GitLab, processes diffs for almost all programming languages, and does not store or retain code.
Teams can keep stakeholders informed, streamline reviews, and reduce manual commentary through inline AI refactoring and weekly progress reports. Granular settings let users skip CI, delay drafts, and limit token consumption. The tool also offers a public changelog and a JSON API for internal use.
