What is GitHub Copilot?
GitHub Copilot is the most installed AI coding assistant in the world, with over 30 million developers using it daily. Built by GitHub (Microsoft) in partnership with OpenAI, Copilot pioneered AI code completion and remains the benchmark for the category.
In 2026, Copilot has evolved significantly: Copilot Chat now supports multi-file context and workspace-level refactoring; Copilot Workspace lets you brainstorm, plan, and implement features from GitHub Issues; and Copilot Code Review automatically reviews your PRs and suggests improvements.
Copilot integrates with VS Code, JetBrains IDEs, Neovim, and GitHub.com — it's wherever developers work.
