Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier. No reason not to use it if you're on Figma. Not worth switching for.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
