Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.B-tier. Still early. Manus is more flexible for less money.
