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 for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
