Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for text-in-image. Use this for posters, Midjourney for art.
