What is Cursor AI?

Claude Code is an AI coding assistant built by Anthropic that integrates directly into your development environment. It helps you handle large codebases, understand unfamiliar code, make edits across multiple files, and run terminal commands without leaving your IDE. The tool is designed to speed up common development tasks like refactoring, debugging, testing, and preparing releases. Rather than requiring you to switch between windows or paste code snippets, Claude Code works alongside you in your existing workflow, offering context-aware suggestions and explanations based on your project structure.
