Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier for social/casual. B-tier for serious work. Good entry point.A-tier in its niche. The only one that actually gets emotion right.
