Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier if you already pay Gemini. B-tier standalone.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
