Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best for teaching a kid to code in 2026.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
