Kai's verdictA-tier for social/casual. B-tier for serious work. Good entry point.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
