  // Tab suggests the entire implementation
}

2. Inline Edit with Cmd+K

Select a function
Press Cmd+K (Windows: Ctrl+K)
"Refactor this function to use async/await and add error handling"

3. Multi-File Feature with Composer

Press Cmd+I (Windows: Ctrl+I)
"@codebase Add authentication to the entire application"

❓ FAQ

Q: How is Cursor different from GitHub Copilot?

A: Cursor is a full IDE (based on VS Code) with integrated AI, while Copilot is an extension. Key differences:

Speed: Cursor Tab is 3x faster (320ms vs 890ms)
Multi-file: Composer can edit multiple files simultaneously
Context: Better codebase indexing and context management
Models: Access to Claude 4.5, GPT-5, Gemini 3, and Cursor's own Composer model
Features: Debug Mode, Parallel Agents, Visual Editor, MCP integration

Q: Does Cursor store my code?

A: No. Code never leaves your machine. Only embeddings (for codebase indexing) are stored server-side, encrypted and obfuscated. Privacy Mode keeps everything local.

Q: Can I use Cursor with my existing VS Code setup?

A: Yes. Cursor is built on VS Code and supports all VS Code extensions, settings, and keybindings. You can import your VS Code configuration.

Q: What's the learning curve?

A: Basic productivity in 15 minutes. Mastery in 4 hours. Most developers see immediate value with Tab and Inline Edit.

Q: How does pricing work?

A: Pro tier ($20/month) includes unlimited requests to all models. Free tier has limited requests. Enterprise tier available for teams.

Q: Can I use Cursor offline?

A: Tab autocomplete works offline (cached model). Composer, Agent, and Chat require internet connection for AI models.

Q: What languages does Cursor support?

A: All languages supported by VS Code. AI features work best with popular languages (TypeScript, Python, Go, Rust, Java, etc.).

Q: How do I get started?

A: Download from cursor.com, install, and follow Part 1: Fundamentals for setup.
