| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier for social/casual. B-tier for serious work. Good entry point. | S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement. | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. |
