Kai's verdictS-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
