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.

Multilingual AI detector with sentence-level insight
The detector is trained for broad language coverage rather than English-only use, which matters for international schools, multilingual newsrooms and cross-border content teams.
After the overall score, a second pass labels each sentence as Human, AI or Mixed and highlights the specific phrases pushing the score up.
Flagged passages are highlighted in the document, and a ranked impact list lets you scroll to the highest-signal sentences first.
Plagiarism checking, grammar proofreading, humanizing, an AI Editor and a presentation maker sit alongside the detector in one account.
