| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier for creators training custom looks. B-tier for general use. | S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement. | S-tier for builders. The right primitives. What Kai is built on under the hood. |
