Overview
GitHub Copilot is GitHub's AI assistant for software development. It offers inline code suggestions, chat for explaining or changing code, repository-aware questions, pull request review, and agentic tasks that can research a repository, edit files, and prepare changes for review. It can also summarize pull requests and explain unfamiliar code. It works across GitHub.com, GitHub Mobile, supported IDEs, and the command line. Copilot is a closed-source service; available features and usage limits depend on the selected plan and organizational policies.
