Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
