Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for builders. The right primitives. What Kai is built on under the hood.A-tier if you already pay Gemini. B-tier standalone.
