Cursor AI

Cursor is a fork of VS Code with AI baked into the core. Cursor Composer (2025) acts as an autonomous engineer that can write/edit multiple files simultaneously.

When to Use

• Productivity: It is currently the fastest way to write code.
• Refactoring: "Refactor this file to use hooks" works instantly.
• Debugging: It sees your terminal errors and fixes them automatically.

Core Concepts

Composer (Cmd+I)

A multi-file editing agent. You describe a feature ("Add a login page with auth middleware") and it creates/edits all necessary files.

Tab Completion (Copilot++)

Predicts your next edit, not just your next word. It predicts cursor movement.
