Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier for sales teams. B-tier for solo users.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
