Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.B-tier. Useful for first drafts. v0 is the better bet for shipping code.
