Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.B-tier. Use Claude + manual SEO thinking.
