Quick answer

The Cursor AI editor is an AI-powered coding environment that provides inline code completions, suggestions, and refactoring using large language models. To use it, install the Cursor extension or app, open your code file, and start typing to receive AI-generated code completions and edits directly in your editor.

PREREQUISITES

Supported code editor (e.g., VS Code)
Cursor AI account or app installed
Internet connection for AI model access

Setup

Install the Cursor AI editor extension or app compatible with your code editor. For example, in VS Code, search for "Cursor AI" in the Extensions Marketplace and install it. Then, sign in with your Cursor account or create one if needed. Ensure you have an active internet connection as the AI completions run via cloud models.

bash

code --install-extension cursorai.cursor-ai

output

Extension 'Cursor AI' installed successfully.

Step by step

Open your code file in the Cursor-enabled editor. Start typing code or comments, and Cursor will automatically show inline AI suggestions. You can accept completions with Tab or Enter. Use keyboard shortcuts or the command palette to trigger AI actions like refactoring, generating tests, or explaining code.

python

def greet(name):
    # Cursor AI suggests:
    return f"Hello, {name}!"

print(greet("World"))

output

Hello, World!

Common variations

You can customize Cursor AI editor settings to change the AI model, suggestion frequency, or enable/disable specific features like code explanation or test generation. Some versions support streaming completions for faster feedback. You can also use Cursor with different programming languages supported by the editor.

Troubleshooting

If AI suggestions do not appear, check your internet connection and ensure you are signed in.
If completions are slow, try switching to a lighter AI model in settings.
Restart the editor if the extension becomes unresponsive.
