Nobody loves code review. You open a PR, scan the diff, catch a typo, approve it, move on. The deeper stuff like pattern consistency and architectural alignment takes real time and real focus. Most of us don't have enough of either. I wanted to build something that catches pattern drift. Not a linter. Not static analysis. Something that understands how your codebase handles a problem and tells you when new code does it differently. Why existing AI reviewers fall short Most AI code review tools see only the diff. They give generic advice like "consider adding error handling" without knowing that your project already has a handleApiError() wrapper used in every API method. The feedback sounds smart but isn't grounded in your codebase. The difference between a generic suggestion and a useful one: Generic: "Consider adding error handling" Pattern-aware: "This bypasses the handleApiError() wrapper used in every other API method.
