Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for speed. When latency is the product, start here.S-tier for text-in-image. Use this for posters, Midjourney for art.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
