Claude Code is Anthropic's AI coding agent. You describe what you want in plain words; it reads your project, explains code, makes changes, runs routine tasks and handles git work. It works in the terminal, in code editors and in the Claude desktop app, and suits developers and anyone comfortable working in project folders.
It comes from the company that makes the Claude models, and the same agent is available in the terminal, your editor and a desktop app.
