Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. No reason not to use it if you're on Figma. Not worth switching for.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
