Kai's verdictS-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.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
