Kai's verdictA-tier for creators training custom looks. B-tier for general use.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
