GitHub Copilot

GitHub Copilot とは？

GitHub Copilot is an AI coding assistant from GitHub that works inside popular editors and on github.com. It suggests code as you type, answers programming questions in a chat panel, and can make multi-step changes through an agent mode. Copilot suits individual developers, students and companies that already use GitHub for their code. Its main strength is breadth of integration: it runs in VS Code, Visual Studio, JetBrains IDEs and other editors, and it connects to GitHub features such as pull requests and issues. Organizations get administrative controls and policy settings, which makes it a common choice for teams that need centralized management.
