Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for social/casual. B-tier for serious work. Good entry point.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for realtime. If latency matters more than voice catalog, start here.
