Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.
