Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for speed. When latency is the product, start here.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for builders. The right primitives. What Kai is built on under the hood.
