Kai's verdictA-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.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
