What is GitHub Copilot?

GitHub Copilot is an AI pair-programmer that suggests code completions, whole functions, and chat-based explanations directly inside editors like VS Code, JetBrains IDEs and Neovim. It can explain unfamiliar code, suggest fixes for errors, generate tests, and — via Copilot Workspace/agent features — take on larger, multi-file tasks. Individual plans are billed monthly per seat; GitHub also offers Business and Enterprise tiers with organization-wide policy controls, and a limited free tier for individual accounts with monthly usage limits. Because Copilot ships as an extension rather than a separate editor, it fits into workflows teams already have rather than requiring anyone to change tools — this is one of the biggest reasons for its wide adoption inside existing engineering organizations. Inline suggestions appear as you type, based on the surrounding code and open files, and can be accepted, modified or ignored without breaking flow. Copilot Chat adds a conversational panel for asking questions about the current codebase, requesting a refactor, or getting an explanation of an error message without leaving the editor. GitHub's education program provides free access to verified students and maintainers of popular open-source projects, which has made it many developers' first exposure to AI-assisted coding. For organizations, Business and Enterprise tiers add policy controls like blocking suggestions that match public code too closely, and audit logging — considerations that matter for companies with strict intellectual-property or compliance requirements around code provenance. As with all AI coding tools, suggestions should be reviewed like any other contributor's code, particularly around security-sensitive logic.
