Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for realtime. If latency matters more than voice catalog, start here.A-tier for social/casual. B-tier for serious work. Good entry point.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
