Kai's verdictA-tier in its niche. The only one that actually gets emotion right.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Close second to Cursor. If $5/mo matters, start here.
