What does WhatTheDiff do?
WhatTheDiff is an AI-powered assistant that integrates directly with your GitHub or GitLab repositories to automate the code review process. It analyzes the differences in your pull requests and automatically generates clear, plain English descriptions of what changed. This saves developers from the tedious task of manually documenting their changes and ensures that every pull request has a comprehensive description. The tool processes the git diff of your code changes using AI models to understand and explain the modifications in a way that's accessible to both technical and non-technical team members.
What sets WhatTheDiff apart is its focus on making code changes understandable for everyone involved in a project. Beyond just generating PR descriptions, it can translate technical changes into simplified summaries for stakeholders who aren't developers. The inline refactoring feature is particularly useful—instead of just commenting on issues during code review, it can suggest and help implement minor fixes directly. The tool supports nearly all programming languages and maintains privacy by not storing your code or using it to train their AI models.
Development teams of all sizes will benefit from WhatTheDiff, especially those looking to streamline their code review workflow and improve communication between technical and non-technical team members. It's perfect for teams that want to maintain better documentation of their changes through automated changelogs and weekly progress reports. The tool is particularly valuable for open-source projects or organizations where keeping stakeholders informed about development progress is crucial for project transparency and collaboration.
