Detailed overview

What The Diff is an AI-powered service for making GitHub pull request changes easier to understand. After a pull request is connected, it analyzes the diff and produces a readable summary that can be used by reviewers, project managers, and other stakeholders. It can update the summary as a pull request changes, helping teams follow the intent of an evolving implementation without manually reconstructing every revision. The service is focused on explanation and communication rather than generating or merging code. It is therefore a lightweight complement to existing review, testing, and continuous integration processes. What The Diff is most useful for teams that use GitHub and want consistent change summaries across repositories, particularly when reviewers are not familiar with every part of the codebase. Organizations should review repository permissions and data handling before enabling an external service on private code.
