GitHub Copilot is an AI coding assistant developed by GitHub, a Microsoft company, to help developers write, understand, modify, test, and review software. It works inside popular development environments and across GitHub, providing features such as inline code completion, AI chat, code generation, code review, agent mode, and cloud-based coding agents.
For people searching for an AI coding assistant, AI programming tool, code completion software, AI code generator, developer productivity tool, or agentic coding assistant, GitHub Copilot is designed to integrate directly into the development workflow rather than requiring developers to move code into a separate chatbot.
Copilot is available through a range of individual and organizational plans, including Copilot Free, which currently provides limited AI coding assistance without a paid subscription. Paid plans add higher usage allowances, additional models, agent capabilities, and other features.
What Is GitHub Copilot?
GitHub Copilot is a generative AI assistant for software development. It can suggest code while a developer types, answer programming questions, generate or modify code, help investigate problems, and support larger development tasks through agentic features.
The assistant is available through supported IDEs, GitHub.com, GitHub Mobile, the command line, and other supported development environments. GitHub describes Copilot as a tool that combines code completion and conversational assistance with increasingly capable agent-based workflows.
Copilot is primarily cloud-connected AI software. The development environment contains the Copilot extension or integration, while AI processing takes place through GitHub’s supported services and models. It is therefore different from a completely offline local AI coding assistant.
GitHub Copilot can be used for many stages of software development, including:
- Writing new code
- Completing code while typing
- Explaining existing code
- Debugging
- Refactoring
- Writing tests
- Creating documentation
- Reviewing code
- Exploring repositories
- Planning implementation tasks
- Performing multi-file development tasks
- Working with supported AI agents
The exact capabilities available depend on the plan, IDE, model, and feature being used. GitHub’s feature matrix is updated as support changes.
Main Uses of GitHub Copilot
AI Code Completion
Code completion is one of GitHub Copilot’s foundational features. As developers type, Copilot can suggest the next portion of code, ranging from individual lines to larger blocks.
This can reduce repetitive typing when implementing common programming patterns, functions, configuration, or boilerplate code.
Copilot supports code completion across several development environments, including Visual Studio Code, Visual Studio, JetBrains IDEs, Eclipse, Xcode, and Neovim, although specific features differ between environments.
Code Generation
Developers can describe a programming task in natural language and ask Copilot to generate code.
For example, a developer might ask for a function that validates user input, processes a dataset, creates an API request, or converts data between formats.
Generated code should still be reviewed, tested, and adapted to the requirements of the project.
Understanding Existing Code
Copilot can explain code and answer questions about a development project.
This can help when working with:
- Unfamiliar repositories
- Legacy code
- New programming languages
- Complex functions
- APIs and libraries
- Large project structures
Workspace indexing and code-referencing features are available in several supported IDEs, allowing Copilot to work with broader project context.
Debugging
Developers can use Copilot Chat to investigate programming errors and ask for explanations or possible fixes.
A developer can provide an error message, selected code, or relevant project context and ask Copilot to explain what may be causing the problem.
The resulting suggestions should be checked against the actual application because AI-generated debugging advice can contain mistakes.
Testing
Copilot can help developers create tests for functions and other code.
It can suggest test cases, generate test implementations, and assist with modifying tests when application code changes.
For larger development tasks, agent mode can also incorporate testing into a broader workflow.
Code Review
GitHub Copilot includes AI-assisted code review features on supported plans and environments. Copilot can analyze code changes and identify potential issues or areas that deserve developer attention.
Code review is particularly relevant for teams that want AI assistance before merging changes, although human review remains important for security, architecture, business requirements, and correctness.
Agentic Software Development
One of the major developments in Copilot is its move beyond traditional autocomplete toward agentic coding.
Agent mode can work through more complex development requests, including analyzing a project, planning changes, editing files, and working through multiple steps.
GitHub also provides a cloud agent for supported paid plans. This allows certain development tasks to be delegated to an agent that works with a repository and produces changes for developer review.
Features
AI Code Completions
Copilot provides real-time code suggestions while developers type. Paid plans currently provide unlimited code completion, while Copilot Free is limited to 2,000 completions per month.
Copilot Chat
Copilot Chat provides a conversational interface for programming questions, explanations, debugging, code generation, and development guidance.
It is available in supported IDEs and on GitHub, with functionality varying by environment and plan.
Agent Mode
Agent mode allows Copilot to work on more complicated coding requests rather than simply returning a text response.
Current GitHub documentation lists agent mode support in Visual Studio Code, Visual Studio, JetBrains IDEs, Eclipse, and Xcode.
Cloud Agent
Copilot’s cloud agent can work on development tasks within GitHub’s environment. It is available on supported paid plans and is intended for more substantial coding workflows.
Next Edit Suggestions
Copilot can suggest subsequent edits based on the changes a developer is making. This feature is supported in several IDEs, with availability varying according to the environment.
Code Review
Copilot provides AI-assisted code review on supported plans and environments, helping developers identify potential issues in code changes.
MCP Support
GitHub Copilot supports the Model Context Protocol (MCP) in supported environments. MCP allows compatible tools and external services to provide additional context and capabilities to AI assistants.
Custom Instructions and Agents
Developers can provide custom instructions that tell Copilot about preferred coding styles, programming languages, response formats, or project conventions.
GitHub also supports custom agents in supported environments.
Multiple AI Models
GitHub Copilot provides access to different AI models depending on the subscription and feature. Paid plans provide broader model-selection capabilities, while Copilot Free uses automatic model selection.
The available model catalog can change over time as GitHub adds, removes, or updates supported models.
