Kai's verdictA-tier for designer-led sites. S-tier if animations matter.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
