Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
