Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.B-tier. Still early. Manus is more flexible for less money.
