GitHub Copilot is an AI coding companion built by GitHub and powered by large language models trained on billions of lines of code. More than just autocomplete, it understands your project context — open files, comments, and coding style - to generate relevant suggestions, explain code, and even fix errors.

It integrates directly into popular IDEs like VS Code, JetBrains, and Neovim, offering seamless inline completions, chat-based assistance, and advanced modes like Copilot Agents that can edit, debug, and automate tasks across your codebase. With support for multiple languages, frameworks, and workflows, Copilot helps individuals and teams move from typing code to reasoning about it - enabling faster development, fewer bugs, and a more creative coding experience.
