| Kai's verdict | 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. | S-tier in the agent category. The first one I'd give to a non-technical friend. | S-tier for text-in-image. Use this for posters, Midjourney for art. |
