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.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
