Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
