Kai's verdictS-tier for text-in-image. Use this for posters, Midjourney for art.A-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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
