Kai's verdictS-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier in the agent category. The first one I'd give to a non-technical friend.
