Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
