Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.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.B-tier. Still early. Manus is more flexible for less money.
