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 search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
