| 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. | S-tier for academic research. Nothing else comes close for systematic reviews. | B-tier. Useful for first drafts. v0 is the better bet for shipping code. |
