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.A-tier. No reason not to use it if you're on Figma. Not worth switching for.S-tier for academic research. Nothing else comes close for systematic reviews.
