Kai's verdictA-tier in its niche. The only one that actually gets emotion right.A-tier for sales teams. B-tier for solo users.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
