Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
