Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.
