Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.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.
