| Kai's verdict | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | 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 inside Photoshop (Generative Fill). B-tier standalone. |
