Gemini Coder — AI-Powered Coding Assistant for VS Code
Take your coding productivity to the next level with Gemini Coder — an AI extension built for real developers who want precision, clarity, and speed.
Unlike other AI tools, Gemini Coder is non-intrusive — it will never modify or suggest code unless you explicitly ask it to. You’re always in control.
You can even view AI-suggested changes before applying them, so nothing gets overwritten unless you’re ready.
