Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for model-shopping. I use this for every prototype before committing.S-tier for builders. The right primitives. What Kai is built on under the hood.
