Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier if you already pay Gemini. B-tier standalone.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
