About GitHub Copilot
GitHub Copilot is an AI pair programmer that integrates directly into popular editors including VS Code, JetBrains IDEs, and Neovim, offering real-time inline code suggestions as developers type. Beyond autocomplete, its Copilot Chat feature answers questions about a codebase in natural language, helps debug errors, and can explain unfamiliar code. Copilot's agent mode can plan and execute larger, multi-file changes, and it also generates pull request summaries and offers command-line suggestions in the terminal. Because it's built by GitHub and owned by Microsoft, it has particularly deep integration with the broader GitHub workflow, including issues, pull requests, and Actions.
