Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier. Still early. Manus is more flexible for less money.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
