AI Diff Summarizer vs
GitHub Diff View
GitHub's diff view is the universal way to read a code change line-by-line. AI Diff Summarizer is the layer on top: paste any diff (GitHub, GitLab, local), get a one-paragraph human summary that tells you what changed and why.

Pick AI Diff Summarizer when…
You're staring at a 600-line diff and want a 3-sentence overview before you start reviewing. Or you just merged something and need a PR description. Or the diff isn't on GitHub at all — it's a local `git diff` or a paste from GitLab/Bitbucket.
Pick GitHub Diff View when…
You're doing the actual code review. Nothing beats GitHub's inline comments, suggestion blocks, threaded review, and tight CI integration when you're hunting for a bug or signing off line-by-line. The diff view is the workspace; the summarizer is the briefing.

Frequently Asked Questions
Which is better for understanding a large PR fast — AI Diff Summarizer or GitHub's diff view?
AI Diff Summarizer gets you a one-paragraph overview in 5 seconds, which is faster than scrolling through 600 lines. Once you have the summary, jump to GitHub for the line-level review.
Is GitHub diff view free?
Yes, for public repositories and within the free GitHub plan. Private repos require a paid plan once you exceed the included seats.
When should I use the native GitHub diff view?
When you're doing line-by-line code review and need inline comments, suggestion blocks, or CI signal alongside the diff. The summary doesn't replace the review; it makes it faster.
Does AI Diff Summarizer work on diffs that are not in GitHub?
Yes. Paste any unified diff — `git diff`, a local patch, a GitLab MR, a Bitbucket PR — and you'll get the same one-paragraph summary.
Do I need a GitHub account to use AI Diff Summarizer?
No. AI Diff Summarizer is a pure paste-in tool. You only need an Anthropic API key (BYO key, no backend cost on our side).
