Where Kanjin fits among AI code review tools.
Most AI code review tools read a pull request after it opens, and comment on it. Kanjin works at another moment: it runs your own agent’s review in the ticket’s worktrees before the pull request exists, and it makes the change shorter for the person who reads it.
-
Kanjin and CodeRabbit
CodeRabbit reviews pull requests on four Git hosts and comments on them, and its Change Stack preview regroups the diff. Kanjin works before the pull request, on your own agent.
-
Kanjin and Greptile
Greptile reviews each pull request with a graph of the codebase, and Fix with your Agent hands its comments to an agent. Kanjin works before the pull request, on your own agent.
-
Kanjin and Copilot code review
Copilot code review comments on pull requests on GitHub, and Fix with Copilot hands a comment to Copilot cloud agent. Kanjin works before the pull request, on your own agent.
-
Kanjin and Qodo
Qodo reviews pull requests on five Git hosts against your rules and tickets, and brings its findings into coding agents. Kanjin takes the whole ticket to a pull request on your own agent.
-
Kanjin and Bugbot
Bugbot reviews pull requests on four Git hosts for bugs and security issues, and hands its fixes to Cursor. Kanjin works before the pull request, on your own agent.
Kanjin, on every comparison
- When it reads the change
- In the ticket’s worktrees, before the pull request exists, and again in the pull request review.
- Who writes the review
- Your own coding agent runs Review, Overengineer and Fix, signed in with your own plan. Then you review the change.
- Where the result goes
- The ticket session and the review in Kanjin. Kanjin never comments on a pull request.
- How you read the change
- In Kanjin’s review: the blocks that preserve behavior fold, and every other change stays on screen, in the original code with its line numbers.
- Fixes
- Fix runs on your agent in the worktrees and checks each finding first. After a push, Fix Failures sends the failed GitHub checks and the open review threads to your agent.
- Approval and merge
- Kanjin never approves a pull request, never merges one, and never labels a change safe to merge.
- Git hosts
- GitHub, GitLab and Bitbucket, and local folders on your Mac.
