GitHub Copilot

GitHub Copilot is the original AI pair programmer, developed by GitHub and powered by OpenAI models. Integrated directly into popular editors, it provides real-time code suggestions as you type — from single-line completions to entire function bodies — making it the most widely adopted AI coding tool among professional developers.

• Code completions — real-time inline suggestions that predict your next lines of code based on context, comments, and function signatures
• Chat assistance — ask Copilot to explain code, fix bugs, generate tests, and write documentation in a conversational sidebar
• Slash commands — use /fix, /tests, /explain, and /doc directly in the editor for quick actions
• Multi-file awareness — understands imports, types, and patterns across your project for more relevant suggestions
• Pull request summaries — automatically generate PR descriptions and review summaries on GitHub.com

Millions of developers use GitHub Copilot daily across every major programming language. It is especially effective for writing boilerplate, implementing standard patterns, generating test cases, and quickly prototyping ideas. Studies show it can improve developer productivity by up to 55% on repetitive tasks.

GitHub Copilot works in VS Code, JetBrains IDEs, Neovim, and Visual Studio, plus directly on GitHub.com and in the GitHub Mobile app.
