Kai's verdictS-tier for aesthetics. If you care how it looks more than how it's made, this wins.A-tier in its niche. The only one that actually gets emotion right.B-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.
