CodeReviewBot.AI plugs directly into GitHub pull requests and posts automated review comments using GPT-4, GPT-4o, and Gemini, covering bugs, security vulnerabilities, performance issues, and style inconsistencies. The goal is catching the kind of issues a tired or rushed human reviewer might miss, consistently, on every single PR rather than only the ones that get a thorough review.
Beyond flagging problems, it can commit ready-to-apply fixes directly, which moves it a step past pure review-and-comment tools toward actually closing the loop on simple, well-understood issues without requiring a developer to write the fix themselves.
It's free for a single repository, with paid plans starting at $9 a month for teams that need it running across more repositories, a low enough price point to make it an easy add-on for small teams rather than a major procurement decision.
