Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
