Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier for social/casual. B-tier for serious work. Good entry point.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in the agent category. The first one I'd give to a non-technical friend.
