Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for speed. When latency is the product, start here.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
