Kai's verdictB-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.S-tier infrastructure. The one platform every AI dev eventually uses.
