What is Claude Code?

Most AI chat tools give you snippets of code that you copy and paste somewhere yourself. Claude Code is different. It works inside a real project folder, on a real computer.

In practice, that means it can:

• Build a project from scratch — files, folders, and all
• Edit existing code and fix bugs
• Run commands, like starting your app or installing what it needs
• Read your files to understand what it is working with
• Explain what it did, in plain English

It works step by step and shows you what it is doing as it goes. You can watch it work, answer its questions, and change direction at any time.

Claude Code is an AI agent — a program you talk to in plain language. It writes and runs the code for you.

It runs in a terminal: the plain text window on a computer where you type instructions. You type what you want, in ordinary sentences. The agent reads your request and works through it step by step.

Claude Code uses your Claude account. What it can do, and how much you can use it, depends on what your Anthropic account or plan includes. For current details, see Anthropic’s Claude Code page.

It runs on whatever computer it is installed on. That can be your own laptop, or a computer in the cloud. More on that below.

No. You describe what you want in plain English, and the agent writes the code.

Two things do help. It helps to be comfortable trying things. And it helps to read what the agent tells you — Claude Code explains what it is doing as it works, and those explanations are how you stay in the loop.

The terminal can look unfamiliar at first. It is just a text window. You are typing sentences, not commands you have to memorize.
