Cursor AI: A Guide With 10 Practical Examples

Cursor AI: An AI-Powered Code Editor Revolutionizing Software Development

Switching between code editors and AI chat interfaces for code assistance is cumbersome. AI-powered code editors, like Cursor AI, integrate AI directly into the coding environment, providing unparalleled context and enhancing output. Trusted by engineers at OpenAI and Perplexity, Cursor AI offers AI-assisted coding, intelligent suggestions, and seamless integration with various development tools.

What is Cursor AI and its Capabilities?

Cursor AI is an AI-powered code editor built to simplify software development. Based on Visual Studio Code (VS Code), it retains VS Code's user-friendly interface and extensive ecosystem, making the transition smooth for existing VS Code users. Leveraging OpenAI's ChatGPT and Claude, Cursor AI offers intelligent code suggestions, automated error detection, and dynamic code optimization.

Key Features:

Autocompletion and Code Prediction: Cursor predicts multi-line edits, adapting to recent code changes. It anticipates your next steps and suggests relevant code. It handles multi-line edits and intelligently corrects or improves code, even with typos. It even predicts your next cursor position for smoother navigation.

Advanced Chat Features: Cursor's chat interface significantly enhances interaction:

• Codebase Queries: Search your entire codebase for relevant information.
• Code Referencing: Easily reference specific code blocks or files within your queries.
• Image Support: Add visual context by dragging and dropping images into the chat.
• Web Search: Access up-to-date information from the internet directly within code queries.
• Instant Application: Implement code suggestions from the chat directly into your codebase with a single click.
• Documentation Integration: Reference popular libraries and add your own documentation for quick access.

Installing Cursor AI

Cursor AI offers free downloads for Linux, Windows, and macOS.

Windows and macOS installations are straightforward. Linux users receive an AppImage file; make it executable using chmod a x cursor-0.40.3x86_64.AppImage and then run it with ./cursor-0.40.3x86_64.AppImage (adjust the version number as needed). Refer to the Cursor website for detailed AppImage installation instructions.

Post-installation, a configuration screen appears:

Configure keyboard shortcuts (VS Code defaults are recommended), select your preferred AI language, enable codebase-wide AI understanding, and optionally add terminal commands.

Ten Cursor AI Use Cases

(MacOS shortcuts using Cmd ⌘ are shown; use Ctrl on Windows/Linux.)

1. Inline Code Generation (Cmd K): Open the inline code generator, enter a prompt, and click "Generate" to add the generated code to your project. Choose your preferred AI model from the dropdown.

2. Interact with Existing Code (Cmd K): Select code, use Cmd K, enter your prompt, and click "Submit Edit" to view changes as a diff (red for deletions, green for additions).

3. Ask Questions about Code (Cmd K): Select code, use Cmd K, enter your question, and click "Quick Question" for an immediate answer.

4. Tab-Based Autocompletion: Cursor suggests AI-generated code completions; use Tab to integrate them. This works with code and natural language descriptions.

5. Chat Interface Overview (Cmd L): Access the versatile chat window for code generation and questions.

6. Code Generation with Chat: Generate code in the chat and click "Apply" to integrate it.

7. Enhancing Queries with @: Use @Web for web searches, @ followed by file/folder names, or GitHub repositories (use cautiously with private data).

8. Global Codebase Questions: Use the codebase option to search your entire project for specific code functionality.

9. Image Support: Drag and drop images into the chat for visual context.

10. Adding Documentation: Use @Docs to add documentation references (URLs) for libraries, accessible via @ documentation name in chat prompts.

Additional Features and Benefits

• Language Support: Cursor supports various programming languages.
• Extensions: Access the extensive VS Code extension ecosystem.
• Collaboration: Use Git and other collaborative tools seamlessly.
• Custom AI Rules: Guide AI behavior through custom rules in settings.
• Custom AI Models: Add and manage your own AI models and API keys.

Cursor AI vs. GitHub Copilot

Both are AI-powered code assistants, but Cursor AI offers deeper integration within its standalone VSCode-based environment, while GitHub Copilot integrates with various popular IDEs. The choice depends on your preferences for customization and ease of setup.

Conclusion

Cursor AI significantly improves coding efficiency by integrating AI directly into the code editor. While Cursor offers a comprehensive standalone solution, other tools like GitHub Copilot offer broader IDE compatibility. The best choice depends on individual needs and preferences.
