# GitHub Copilot - Your autonomous AI peer programmer

**[GitHub Copilot](https://code.visualstudio.com/docs/copilot/overview)** is an AI peer programming tool that transforms how you write code in Visual Studio Code.

GitHub Copilot agents handle complete coding tasks end-to-end, autonomously planning work, editing files, running commands, and self-correcting when they hit errors. You can also leverage inline suggestions for quick coding assistance and inline chat for precise, focused edits directly in the editor.

**Sign up for [GitHub Copilot Free](https://github.com/settings/copilot?utm_source=vscode-chat-readme&utm_medium=first&utm_campaign=2025mar-em-MSFT-signup)!**

## Getting access to GitHub Copilot

Sign up for [GitHub Copilot Free](https://github.com/settings/copilot?utm_source=vscode-chat-readme&utm_medium=second&utm_campaign=2025mar-em-MSFT-signup), or request access from your enterprise admin.

To access GitHub Copilot, an active GitHub Copilot subscription is required. You can read more about our business and individual offerings at [github.com/features/copilot](https://github.com/features/copilot?utm_source=vscode-chat&utm_medium=readme&utm_campaign=2025mar-em-MSFT-signup).

## Build with autonomous agents

**Let AI agents implement complex features end-to-end**. Give an agent a high-level task and it breaks the work into steps, edits multiple files, runs terminal commands, and self-corrects when it hits errors or failing tests. Agents excel at [building new features](https://code.visualstudio.com/docs/copilot/agents/overview), [debugging and fixing failing tests](https://code.visualstudio.com/docs/copilot/guides/debug-with-copilot), refactoring codebases, and [collaborating via pull requests](https://code.visualstudio.com/docs/copilot/agents/cloud-agents).

**Manage sessions from a central view.** Run multiple [agent sessions](https://code.visualstudio.com/docs/copilot/chat/chat-sessions) in parallel and track them in one place. Monitor session status, switch between active work, review file changes, and resume where you left off.

**Run agents with your preferred harness.** Use agents locally in VS Code, in the background via Copilot CLI, or Cloud via Copilot Coding Agent. You can also work with providers like Claude and Codex, and hand tasks off between agent types with context preserved all within the VS Code.

**Use agents to [plan before you build](https://code.visualstudio.com/docs/copilot/agents/planning) with the Plan agent**, which breaks tasks into structured implementation plans and asks clarifying questions. When your plan is ready, hand it off to an implementation agent to execute it. You can also [delegate tasks to cloud agents](https://code.visualstudio.com/docs/copilot/agents/cloud-agents) that create branches, implement changes, and open pull requests for your team to review.

## More ways to code with AI

**Receive intelligent inline suggestions** as you type with [ghost text suggestions](https://aka.ms/vscode-completions) and [next edit suggestions](https://aka.ms/vscode-nes), helping you write code faster. Copilot predicts your next logical change, and you can accept suggestions with the Tab key.

**Use inline chat for targeted edits** by pressing `Ctrl+I`/`Cmd+I` to open a chat prompt directly in the editor. Describe a change and Copilot suggests edits in place for refactoring methods, adding error handling, or explaining complex algorithms without leaving your editor.

## Customize AI for your workflow

**Agents work best when they understand your project's conventions and have the right tools**. Tailor Copilot so it generates code that fits your codebase from the start.

**Project context.** Use [custom instructions](https://code.visualstudio.com/docs/copilot/customization/custom-instructions) to specify project-wide or task-specific context and coding guidelines.

**Add specialized capabilities**. Teach Copilot specialized capabilities with [agent skills](https://code.visualstudio.com/docs/copilot/customization/agent-skills) or define specialized personas with [custom agents](https://code.visualstudio.com/docs/copilot/customization/custom-agents).

**Connect to external tools and services**. Extend agents further with tools from [MCP servers](https://code.visualstudio.com/docs/copilot/customization/mcp-servers) and extensions to give Copilot a gateway to external data sources, APIs, or specialized tools.

### Supported languages and frameworks

GitHub Copilot works on any language, including Java, PHP, Python, JavaScript, Ruby, Go, C#, or C++. Because it’s been trained on languages in public repositories, it works for most popular languages, libraries and frameworks.

### Version compatibility

As Copilot Chat releases in lockstep with VS Code due to its deep UI integration, every new version of Copilot Chat is only compatible with the latest and newest release of VS Code. This means that if you are using an older version of VS Code, you will not be able to use the latest Copilot Chat.

Only the latest Copilot Chat versions will use the latest models provided by the Copilot service, as even minor model upgrades require prompt changes and fixes in the extension.

### Privacy and preview terms

By using Copilot Chat you agree to [GitHub Copilot chat preview terms](https://docs.github.com/en/early-access/copilot/github-copilot-chat-technical-preview-license-terms). Review the [transparency note](https://aka.ms/CopilotChatTransparencyNote) to understand about usage, limitations and ways to improve Copilot Chat during the technical preview.

Please refer to our [Privacy Statement](https://docs.github.com/en/site-policy/privacy-policies/github-privacy-statement) to learn about the data we collect, how we use it, and the controls available to you.

To get the latest security fixes, please use the latest version of the Copilot extension and VS Code.
