Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. Best for teaching a kid to code in 2026.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.
