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. Category leader. Nothing else is close yet.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
