| Kai's verdict | S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement. | S-tier. Category-defining UX. If you take notes in meetings, switch this week. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for academic research. Nothing else comes close for systematic reviews. |
