Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for builders. The right primitives. What Kai is built on under the hood.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for text-in-image. Use this for posters, Midjourney for art.
