WhatTheDiff is a developer assistant that explains pull requests, summarizes diffs, and drafts changelogs automatically.

Summary

WhatTheDiff allows you to summarize pull requests, explain code changes, and draft changelogs so reviews are faster and more informative.

WhatTheDiff Review

WhatTheDiff is a pull request assistant that reads diffs, summarizes changes, and proposes review-ready descriptions and checklists. It explains the impact by files and functions, flags risky modifications, and can draft tests or refactors aligned to style guides. Reviewers get concise context to speed approvals, and labels and comments apply automatically. Integrations with Git providers and CI gate merges based on rules. The value is faster, clearer code reviews with less manual summarizing.

Things to Know About WhatTheDiff

WhatTheDiff drawbacks: Code summaries can miss edge cases or architectural implications, requiring human review. Language and framework coverage is uneven for niche stacks. Private repo access raises security concerns without tight scopes and audit logs. Excessive commentary can create noise in PRs, and CI integration needs careful configuration.
