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 product but crowded market. Try it if Notion AI feels too generic.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
