Kai's verdictA-tier for designer-led sites. S-tier if animations matter.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
