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 for speed. When latency is the product, start here.S-tier for academic research. Nothing else comes close for systematic reviews.
