I Asked ChatGPT to Review My Code. Here's What It Missed (And What It Caught)

Everyone's using AI for code review now. But is it actually good at it? I ran an experiment. I took 5 real pull requests from my projects and asked ChatGPT (GPT-4) to review them. Then I compared its feedback to what a senior developer found. The results were. mixed. What AI Code Review Caught 1. Obvious Bugs (10/10) AI is shockingly good at spotting basic errors: // AI caught this immediately func divide ( _ a: Int, by b: Int ) -> Double { return Double ( a ) / Double ( b ) // No zero check! } It flagged the missing zero division check, suggested a guard statement, and even wrote the fix.
