Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
