Kai's verdictS-tier infrastructure. The one platform every AI dev eventually uses.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.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.
