Kai's verdictS-tier for aesthetics. If you care how it looks more than how it's made, this wins.A-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. Still early. Manus is more flexible for less money.
