The complete guide

What is Claude Code?

A plain-English guide to Anthropic's AI coding agent - what it is, how it works, what you can build with it, and how to start, even if you've never written a line of code.

What is Claude Code?

Claude Code is an AI coding agent built by Anthropic. You describe what you want in plain English, and it works directly inside your project - reading and editing your real files, running commands, checking the results, and fixing what breaks until the job is done. Think of it less like a chatbot and more like a capable developer you can hand a task to and trust to carry it out.

It runs in your terminal (and connects to your editor), so it isn't tied to any one app. That combination - natural language in, real changes to a real codebase out - is what makes it feel different from the AI tools most people have tried.

How Claude Code works

Under the hood, Claude Code is powered by Anthropic's Claude models. What makes it an agent rather than just a chatbot is that it can take actions: it reads the files in your project for context, makes edits across as many files as a task needs, runs your commands and tests, reads the output, and iterates. You stay in control - approving changes and steering - while it does the heavy lifting.

It also keeps context. A simple CLAUDE.md file lets you give it standing instructions about your project, and it can be extended with MCP servers, skills, subagents, and hooks to connect to your tools and data. If those terms are new, our glossary explains each one in plain English.

What you can build with it

Because it works on real projects in any stack, the range is wide. People use Claude Code to build websites, web and mobile apps, automations, AI agents, internal tools, data scripts, and full SaaS products. It's just as useful on an existing codebase as it is starting from scratch.

  • Marketing sites and landing pages
  • Web and mobile apps
  • Automations that save hours a week
  • Custom AI agents and assistants
  • MCP servers that connect your tools
  • Client work and internal dashboards

Who Claude Code is for

The short answer: anyone who can describe what they want. Experienced developers use Claude Code to move faster and offload tedious work. But it has also opened the door for people who have never written a line of code - founders, creators, marketers, students - to build things they previously had to hire out.

We've built dedicated guides for each kind of builder - see Claude Code for beginners, for founders, and for creators.

How it differs from ChatGPT, Copilot & Cursor

It's easy to lump all AI coding tools together, but they work at different levels. ChatGPT is a general chat assistant you copy code out of. GitHub Copilot autocompletes lines as you type inside your editor. Cursor is an AI-first editor. Claude Code is an agent that takes whole tasks and completes them across your project - no copy-paste loop, no babysitting each line.

We break each one down fairly on our comparisons page - including Claude Code vs ChatGPT and Claude Code vs Cursor.

How to get started

Getting started is simpler than most people expect. You set up access through Anthropic, install Claude Code, point it at a project (or an empty folder), and describe your first build. The hardest part isn't installation - it's knowing how to direct an agent well so you get great results instead of frustrating ones.

That's exactly what Claude Code Club teaches. For $9/month you get a structured curriculum, proven templates, weekly lessons, and a community of 4,500+ builders who help you ship your first real project in week one. See the curriculum or pricing to dig in.
