GitHub Copilot Chat

GitHub Copilot Chat is a conversational AI coding assistant that answers coding questions and proposes code changes with awareness of your open files and repository context, available on GitHub.com, in GitHub Mobile, in supported integrated development environments (IDEs), and in the Copilot CLI.

Within editors such as Visual Studio Code, Visual Studio, JetBrains IDEs, Xcode, and Eclipse, Copilot Chat can explain selected code, suggest fixes, and generate unit tests in an inline or dedicated chat view. It supports context controls like mentioning files or symbols and can operate in ask mode for questions, plan mode for drafting an implementation plan, or agent mode for multi file updates and task style work, helping scaffold features, refactor code, and iterate on changes while you review and apply them.
