Kai's verdictB-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 multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
