Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.S-tier in its category. The first AI music tool I'd actually listen to.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.
