Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
