Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.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.A-tier in its niche. The only one that actually gets emotion right.
