Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
