Gemini AI Assistant for Visual Studio 2022

A powerful AI-driven coding assistant for Visual Studio 2022, powered by the Google Gemini API. It integrates seamlessly into the editor's right-click context menu and provides intelligent code assistance for any programming language.

✨ Features

🏷️ AI Symbol Rename (3 suggestions)

Place your cursor on any symbol (variable, class, function, etc.) — no selection needed — and invoke the command. A custom UI window appears with 3 context-aware naming suggestions generated by Gemini. Choose a suggestion or type your own name, click Apply, and the rename is applied silently across the entire solution.

Works for C++, C#, and any other language supported by Visual Studio.

💬 Add Comments

Select a block of code and let Gemini add clear, concise comments to it. The AI strictly mimics the existing commenting style found in your file — if you use // line comments, it will use those; if you use Doxygen/XML, it will match that too.

🎨 Design Refactor

Improves naming conventions, readability, and indentation of the selected code according to language-specific best practices.

🔧 Code Refactor

Finds and fixes potential bugs, applies SOLID principles, architectural improvements, and performance optimizations.

🚀 Full Refactor

A deep architectural refactoring — applies design patterns, memory optimizations, composition over inheritance, and comprehensive documentation comments.
