GitHub Copilot

GitHub Copilot is an AI assistant from GitHub that helps you write, understand and ship software. It suggests code as you type, answers questions about a codebase, reviews your changes and works on tasks you assign it.

What GitHub Copilot does

  • Suggests code as you type and from plain-language prompts.
  • Answers questions about files, repositories and development concepts.
  • Works through a goal in several steps as an agent: it researches a repository, proposes a plan, edits files and prepares a pull request for you to review.
  • Reviews code and pull requests, with summaries and suggestions for improvement.
  • Can be shaped to your project with instructions, reusable prompts, repository context, external tools (including MCP servers) and custom agents.
  • Runs in GitHub, in your editor, on the command line and in project tools, so a change can start as an issue and come back as a pull request.

What people use it for

  • Understand unfamiliar code

    Ask questions about a file or a whole repository, and about the concepts behind it, without leaving the place you work.

  • Hand off a defined task

    GitHub describes a change that starts as an issue, is picked up by an agent, comes back as a pull request, is reviewed and merged. You review and approve each step.

  • Review a pull request

    Get a summary of a change and suggestions for potential improvements before a person reads it closely.

  • Build from a description

    Describe an application in natural language and have Copilot draft it, then change and fix it by asking.

Who it suits

  • Developers who already work in GitHub and want an assistant inside the same workflow of issues, pull requests and reviews.
  • Teams that want one assistant across the editor, the command line and GitHub, with settings an organisation can manage.

Plans and access

GitHub offers a free plan for trying core features, paid plans for individuals and plans for businesses. What you can use depends on the plan, the client and your organisation’s policies, so read GitHub’s current plans page before you decide.

How to start

  1. 1Try the free plan to see how it feels in your own code. Open
  2. 2Use it where you already work: in your editor or on github.com. Open
  3. 3Begin by asking a question about code you know, then let it suggest a small change and read every line it proposes.
  4. 4Move to an agent task only once you are comfortable reviewing its work as you would a colleague’s pull request.
