| Kai's verdict | B-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. | A-tier for its niche. Different use case than Suno — SFX and loops, not songs. | A-tier for creators training custom looks. B-tier for general use. |
