GitHub Copilot is an AI coding assistant developed by GitHub and powered by large language models. It integrates into popular code editors such as Visual Studio Code, Visual Studio, JetBrains IDEs, Vim, and Neovim, as well as GitHub.com itself. The tool offers line-by-line and whole-function code completions, a conversational chat interface for explaining code, generating tests, and fixing bugs, and an agent mode capable of handling multi-step coding tasks autonomously. Copilot supports multiple programming languages and can reference a repository's codebase for context-aware suggestions. It is available to individual developers, teams, and enterprise organizations, with enterprise tiers adding policy controls, audit logs, and the ability to fine-tune the model on internal codebases. GitHub Copilot is designed to reduce repetitive coding tasks, accelerate onboarding, and assist with code review and documentation generation.
