Kai's verdictB-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.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for builders. The right primitives. What Kai is built on under the hood.
