How to Use Cursor AI: Complete Beginner Guide (2026)

Cursor is an AI-powered code editor built on VS Code. It looks and feels like VS Code, but with built-in AI that can write code, refactor files, debug errors, and chat with you about your codebase. If you've used VS Code before, you already know 90% of Cursor.

This guide covers everything you need: installation, your first AI-powered task, key features, and when Cursor is the right tool (versus Claude Code or other AI tools).

In this guide:

• What Cursor AI does
• Installation and setup (3 minutes)
• Your first AI coding task
• Key features and shortcuts
• Cursor AI pricing
• When to use Cursor vs other tools

What Cursor AI Does

Cursor is a code editor with AI deeply integrated. Unlike a chatbot where you copy-paste code back and forth, Cursor's AI can:

• Edit code in place -- click a file, ask for a change, see it applied directly
• Understand your entire codebase -- it reads multiple files to understand context
• Write multi-file features -- describe what you want, Cursor creates or edits all necessary files
• Debug errors inline -- paste an error, Cursor finds and fixes the cause
• Auto-complete as you type -- AI suggestions appear as you write code (like Copilot on steroids)

The key difference from browser-based AI: Cursor lives inside your editor. The AI sees your files, your cursor position, your terminal output, and your git history. It has the context that ChatGPT or Claude.ai lack.

For a terminal-based alternative, see our Claude Code beginner guide.

Installation and Setup

Step 1: Download Cursor

Go to cursor.com and download the installer for your operating system. Cursor is available for macOS, Windows, and Linux.

The download is about 150MB. Installation takes under a minute.

Step 2: Import Your VS Code Settings (Optional)

If you use VS Code, Cursor will prompt you to import your settings on first launch. This brings over:

• Your extensions (most VS Code extensions work in Cursor)
• Your keybindings
• Your themes and settings
• Your snippets

If you skip this, you can import later from the Command Palette (Cmd+Shift+P → "Cursor: Import VS Code Extensions").

Step 3: Open a Project

Open a folder or clone a repo, just like you would in VS Code:

File → Open Folder → Select your project

Cursor indexes your project files in the background. For most projects, indexing takes 10-30 seconds.

Step 4: Start Using AI

You're ready. Open the AI chat panel with Cmd+L (macOS) or Ctrl+L (Windows/Linux).

Type a question or instruction:

What does this project do? Give me a brief summary.

Cursor reads your files and responds with a summary. Total setup time: about 3 minutes.

Your First AI Coding Task

Example 1: Ask About Your Code

Press Cmd+L to open the chat panel:

Explain what the handleSubmit function does in src/components/LoginForm.tsx

Cursor reads the file and explains the function in plain English. It references specific lines and variables from your code.

Example 2: Generate a Feature

Open a file, then press Cmd+K to open the inline edit bar:

Add form validation that checks:
- Email is valid format
- Password is at least 8 characters
- Both fields are required
Show error messages below each input

Cursor edits the file directly. You see the diff and can accept or reject changes.

Example 3: Debug an Error

Copy an error message from your terminal, then in the chat panel:

I'm getting this error when I click "Submit":

TypeError: Cannot read properties of undefined (reading 'email')
  at LoginForm.tsx:42

Fix it.

Cursor reads the file, finds the bug, and suggests a fix. It explains what was wrong and why the fix works.

Example 4: Create a New File

In the chat panel:

Create a new file src/hooks/useAuth.ts with a React hook that:
- Checks if the user is logged in
- Provides login/logout functions
- Stores the auth token in localStorage
- Returns the current user object

Cursor creates the file with the complete implementation.

Key Features and Shortcuts

Chat Panel (Cmd+L / Ctrl+L)

The chat panel is your main interface for asking questions and getting explanations. It works like a conversation with an AI that has full context of your codebase.

Features:

• @-mention files: Type @filename to include specific files in the conversation
• @-mention docs: Type @docs to search documentation
• @-mention web: Type @web to search the internet for current information
• Code blocks are clickable: Click any code block to apply it to the corresponding file

Inline Edit (Cmd+K / Ctrl+K)

Select code and press Cmd+K to edit it with AI. Or press Cmd+K without a selection to generate new code at your cursor position.

This is Cursor's most powerful feature. Instead of describing what to change and copying code from a chat, you just tell Cursor what to do and it edits the file directly.

Composer (Multi-File Edits)

Press Cmd+I to open Composer, which can edit multiple files simultaneously. This is for larger tasks:

Add user authentication:
1. Create a login page component
2. Add an /api/auth/login endpoint
3. Create an auth middleware
4. Update the navbar to show login/logout
5. Add protected route logic

Composer creates and edits all files in one operation. You review each change individually.

Tab Completion

As you type, Cursor suggests completions. Press Tab to accept. Unlike basic autocomplete, Cursor's completions consider:

• Your current file and cursor position
• Other files in your project
• Your recent edits in the same session
• Common patterns in your codebase

Keyboard Shortcuts Reference

Cursor AI Pricing

Premium requests use the best models (Claude 3.5 Sonnet, GPT-4o). Free-tier requests use lower-cost models that are still good but less capable.

Is Cursor Pro worth $20/month? If you use AI coding daily, yes. The 500 premium requests cover most full-time developers. If you hit the limit, completions still work (they're unlimited) -- only chat and Composer requests count against the premium limit.

When to Use Cursor vs Other Tools

Cursor vs VS Code + Copilot

Cursor has deeper AI integration than VS Code + GitHub Copilot. Copilot provides inline completions. Cursor provides inline completions PLUS a chat panel, multi-file edits (Composer), and codebase-aware responses.

Choose Cursor if: You want AI deeply integrated into your editor, not just as an autocomplete overlay.

Choose VS Code + Copilot if: Your company mandates VS Code, or you only need basic completions.

Cursor vs Claude Code

Claude Code is a terminal-based AI agent. Cursor is a visual code editor with AI. They serve different workflows.

Choose Cursor if: You prefer a visual editor with a GUI chat panel. You want to see files, navigate with a sidebar, and use mouse + keyboard.

Choose Claude Code if: You prefer the terminal. You want AI to run commands, execute scripts, and work across your entire system (not just the editor). See our Claude Code beginner guide for the full tutorial.

For the detailed comparison, see Claude Code vs Cursor.

Cursor vs Windsurf

Windsurf (by Codeium) is another AI code editor. It's newer and uses a different AI approach (Cascade flows).

Choose Cursor if: You want a mature, stable AI editor with the largest community. Cursor has been around longer and has more polished features.

Choose Windsurf if: You want a free alternative with strong AI capabilities. Windsurf's free tier is more generous than Cursor's.

See our Windsurf vs Cursor comparison for benchmarks.
