AI code review, PR triage, and security monitoring for fast-moving teams
Every pull request gets line-level comments that draw on repository-wide context, coding guidelines and related files rather than just the diff in isolation.
Comments ship with one-click fixes, and CodeRabbit will iterate with human authors or coding agents until the feedback is resolved and re-verified.
Scores, ranks and routes incoming pull requests so high-impact changes are reviewed first and routine ones fast-track, with a board view of the queue.
Semantic diffs, blast-radius analysis and architecture diagrams make very large, agent-generated changes understandable in a few minutes.
Private, in-browser text and code diff checker with word-level highlighting
Read changes in two columns side by side, or switch to a single-column unified diff in the same format as git diff and patch files.
Darker highlights mark the exact words and characters that changed inside a modified line, not just the lines that differ.
The comparison runs entirely in your browser, so confidential code, contracts and config files never leave your device.
Ignore whitespace, indentation and capitalisation differences, and control how much unchanged context is shown around each change.
