Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for text-in-image. Use this for posters, Midjourney for art.
