GitHub Copilot

GitHub Copilot is your AI pair programmer, delivering real-time code suggestions, generating unit tests, and summarizing pull requests directly in your IDE.

GitHub Copilot acts as your generative AI pair programmer, accelerating development by suggesting lines and entire functions in real time, often appearing as 'ghost text' directly in your IDE (VS Code, Visual Studio, JetBrains IDEs). Leveraging models like GPT-4.1, it moves beyond simple completions: developers use Copilot Chat for complex tasks like generating unit tests, explaining code, or using Copilot Edits to make changes across multiple files from a single natural language prompt. This tool integrates deeply into the workflow, from code creation to AI-generated pull request summaries, significantly boosting developer productivity.
