Supercharge Your Coding with AI-Powered IntelliCode Suggestions

IntelliCode by Microsoft is an intelligent extension built into Visual Studio and Visual Studio Code, designed to help developers write better code faster. It’s the best AI tool for Development & Coding teams looking to leverage smart AI-assisted recommendations, code refactoring, and contextual IntelliSense suggestions. IntelliCode uses machine learning trained on thousands of open-source projects on GitHub to predict your next line of code with remarkable accuracy — making it one of the best AI coding assistants for C#, Python, JavaScript, and more.

This free tool works natively in Microsoft’s IDEs, so there’s no complex setup or extra hardware needed — simply install or update Visual Studio or VS Code and IntelliCode is ready to go. It supports team training with custom models to adapt suggestions to your project’s specific patterns and codebase, boosting productivity and consistency.

IntelliCode keeps security front of mind: all your proprietary code stays local when training custom models. It’s easy to onboard developers because IntelliCode integrates naturally with the IDE they’re already using — no context switching, no steep learning curve.

As a Microsoft-backed tool, IntelliCode benefits from constant updates and integration with the latest AI advancements, ensuring it remains scalable and future-proof for teams of any size. From repetitive coding tasks to smarter code reviews, IntelliCode helps developers stay focused, write cleaner code, and deliver faster.

Visual Studio IntelliCode is like having an AI pair programmer that understands your coding style.
