Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for builders. The right primitives. What Kai is built on under the hood.
