Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Useful for first drafts. v0 is the better bet for shipping code.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Still early. Manus is more flexible for less money.
