Kai's verdictS-tier for builders. The right primitives. What Kai is built on under the hood.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
