Kai's verdictS-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.S-tier in its category. The first AI music tool I'd actually listen to.B-tier. Still early. Manus is more flexible for less money.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
