1.2 How Claude Differs from Other AI Coding Tools

1.3 Installing and Accessing Claude Code

Setting up Claude Code is straightforward, but understanding its access modes will help you choose the one that fits your workflow. Anthropic provides several ways to use Claude Code—through the Claude web interface, the Claude API, or editor integrations such as VS Code, Cursor, and Zed. Each option offers the same reasoning power but differs in how it connects to your local environment. The key is to start simple, verify functionality, and then expand to more advanced integrations as you grow comfortable.

The easiest way to begin is through the Claude web application at claude.ai. After creating an Anthropic account, you can access Claude directly in your browser. The web interface includes Claude’s general and coding modes. When you choose “Claude Code,” the model adjusts its internal reasoning to focus on syntax generation, debugging, and contextual analysis. You can upload code files, paste snippets, or describe problems in natural language. The responses you receive include annotated code, explanations, and sometimes even testing guidance. This interface is ideal for learning prompt patterns before you move into a fully integrated setup.

For developers who prefer automation or custom environments, Anthropic’s Claude API offers more control. You’ll need an API key, obtainable through your Anthropic account dashboard. Once you have the key, you can install the official anthropic Python package and interact with Claude programmatically. The API allows you to build custom scripts, integrate Claude into development pipelines, or even create AI-driven code review bots. Here’s a simple example:
