GitHub Copilot
GitHub's AI pair programmer for code completions and autonomous agent workflows.
What is GitHub Copilot?
GitHub Copilot is Microsoft's AI coding assistant embedded in VS Code, JetBrains, and other editors. It offers inline completions plus an agent mode that plans changes, edits across files, and opens pull requests.
Who is GitHub Copilot best for?
Professional developers who want AI completions inside their existing IDE and increasingly want an agent to handle multi-file tasks and PRs.
How does GitHub Copilot work?
Ghost-text suggestions appear as you type, while agent mode takes a high-level goal, indexes the repo, edits code, runs validations, and opens a PR for review.
