Kai's verdictA-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.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier in the agent category. The first one I'd give to a non-technical friend.
