Kai's verdictA-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.S-tier in the agent category. The first one I'd give to a non-technical friend.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
