Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
