Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.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.S-tier for text-in-image. Use this for posters, Midjourney for art.
