Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for speed. When latency is the product, start here.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for builders. The right primitives. What Kai is built on under the hood.
