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.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
