Kai's verdictA-tier. Great price/performance. Go here if ElevenLabs is too expensive.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.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
