Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier in the agent category. The first one I'd give to a non-technical friend.B-tier. Still early. Manus is more flexible for less money.
