About GitHub Copilot
GitHub Copilot is an AI coding assistant developed by GitHub and OpenAI that plugs directly into your existing editor rather than replacing it. It offers code completions, an in-editor chat, an autonomous coding agent, and automated pull request reviews across IDEs including VS Code, JetBrains, and Visual Studio. Since June 2026 GitHub moved from flat-fee to a usage-based AI Credits model: every plan now includes a monthly credit pool shared across chat, agent mode, and code review. Copilot remains the most GitHub-native option, with deep integration into pull requests, Actions, and organization-wide policy controls that make it the default choice for teams already standardized on GitHub.
