Kai's verdictB-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier in its niche. The only one that actually gets emotion right.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
