Kai's verdictA-tier in its niche. The only one that actually gets emotion right.A-tier if you already pay Gemini. B-tier standalone.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
