We switched away from Claude and OpenAI(Codex) for code reviews. Cognition(Devin) is doing the job better. There, I said it. Last week, 4 devs at DialNexa merged 138 PRs. Devin reviewed every single one. 412 bugs caught. Fixed. Shipped clean. Not after production incidents. Not after customer complaints. Before any of that. Now here's the part that will bother some of you. I have nothing against Claude or Codex. We use Claude daily. But for code review specifically, Devin is winning. And the reason is embarrassingly simple. Multi-repo context. When Devin reviews a PR, it does not look at the diff in isolation. It understands how that change interacts across your entire codebase. Claude and Codex, without that context, are essentially reviewing a page torn out of a book. Good reviewers are not fast readers. They are people who understand the whole system. Devin gets that. The others don't, yet. The setup is not complicated. Auto review on PR merge. That's it. You are sorted. No workflow overhaul. No new rituals. Just a silent reviewer that never gets tired, never skips Friday PRs, and never lets something slide because the standup ran long. If you are using AI for code review and not getting this kind of output, the tool is not the problem. The context is. Are you giving your AI reviewer enough of the picture to actually catch what matters?
