Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
