Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. If you're on Vercel/shadcn, this is cheating.
