Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
