Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier. Category leader. Nothing else is close yet.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
