Kai's verdictS-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.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for teachers. If you teach K-12, start here this week.
