Kai's verdictB-tier. Still early. Manus is more flexible for less money.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
