Kai's verdictA-tier in its niche. The only one that actually gets emotion right.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
