Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for search. I use it before Google now.
