Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.S-tier for teachers. If you teach K-12, start here this week.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
