Kai's verdictS-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier in its niche. The only one that actually gets emotion right.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
