Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier inside Photoshop (Generative Fill). B-tier standalone.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
