Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Close second to Cursor. If $5/mo matters, start here.S-tier in its category. The first AI music tool I'd actually listen to.
