Kai's verdictA-tier for designer-led sites. S-tier if animations matter.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
