Kai's verdictB-tier. Still early. Manus is more flexible for less money.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
