Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for model-shopping. I use this for every prototype before committing.
