Kai's verdictB-tier. Still early. Manus is more flexible for less money.S-tier for speed. When latency is the product, start here.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
