Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier in its category. The first AI music tool I'd actually listen to.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
