Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for solo + free. The best free option, hands down.
