Kai's verdictS-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.A-tier for designer-led sites. S-tier if animations matter.S-tier for builders. The right primitives. What Kai is built on under the hood.
