Kai's verdictS-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
