Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for speed. When latency is the product, start here.S-tier for text-in-image. Use this for posters, Midjourney for art.
