Kai's verdictS-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.S-tier for builders. The right primitives. What Kai is built on under the hood.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
