| Kai's verdict | S-tier. Category leader. Nothing else is close yet. | S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement. | A-tier in its niche. The only one that actually gets emotion right. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. |
