Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
