Build Your Own ChatGPT Safety Net: A Simple Chrome Extension Tutorial

Tired of accidentally sharing sensitive data with ChatGPT? This tutorial shows you how to build a simple Chrome extension – a "molly-guard" – to protect your privacy. We'll guide you through five easy steps, using basic web technologies.

Key Takeaways:

• ChatGPT Protection: Learn to create a Chrome extension that prevents the submission of messages containing specified sensitive words or phrases.
• Easy-to-Follow Steps: This tutorial breaks down the process into manageable steps, perfect for beginners.
• Enhanced User Experience: The extension provides visual cues, improving safety and usability.

What We're Building:

AI assistants are incredibly helpful, but accidental oversharing is a real concern. This "molly-guard" extension acts as a safety net. You define a list of sensitive words or phrases. If you try to submit a message containing any of these words, the extension will disable the submit button, preventing accidental disclosure.

Before You Begin:

• A ChatGPT account (free signup available).
• Basic understanding of HTML, CSS, and JavaScript.
• The code for this tutorial is available on GitHub (link to GitHub repo here).

What is a Chrome Extension?

A Chrome extension is a small program that enhances your Chrome browsing experience. They're built using HTML, CSS, and JavaScript and range from simple tools to complex applications. Many are available on the Chrome Web Store. For a deeper dive, consult Google's official documentation (link to Google's documentation here). This tutorial uses a content script, allowing interaction with a specific webpage's content (in this case, ChatGPT).

Step 1: Setting Up Your Extension Files

Create a new folder named chatgpt-molly-guard and add these files:

• manifest.json: Metadata about your extension (name, version, permissions, etc.).
• contentScript.js: The main JavaScript code that monitors the ChatGPT input.
• wordsList.js: A list of your sensitive words (easily customizable).
• styles.css: (Optional) Styling for visual cues.

Step 2: The manifest.json File

This JSON file tells Chrome about your extension. Paste this code into manifest.json:

{
  "manifest_version": 3,
  "name": "ChatGPT Molly-guard",
  "version": "1.0",
  "description": "Prevents submission of messages containing sensitive words.",
  "content_scripts": [
    {
      "matches": ["https://chat.openai.com/*"],
      "css": ["styles.css"],
      "js": ["wordsList.js", "contentScript.js"]
    }
  ]
}

Key Manifest Elements Explained:

• "manifest_version": Specifies the manifest file format version (use 3).
• "name", "version", "description": Basic information about your extension.
• "content_scripts": Defines which scripts to run on which websites ("https://chat.openai.com/*" targets ChatGPT).

Step 3: The contentScript.js File

This script monitors the ChatGPT input field. Paste this code into contentScript.js:

// ... (Debounce function and other code as provided in the original input) ...

(Include the full contentScript.js code from the original input here)

This code uses a debounce function to efficiently check for sensitive words and updates the UI accordingly (disabling the submit button and adding a red border). Event delegation is used to handle dynamic UI updates in ChatGPT.

Step 4: Styling with styles.css

Add this code to styles.css for visual cues:

.forbidden-div {
  border: 2px solid red !important;
  background-color: #ffe6e6 !important;
}

This styles the input area when sensitive words are detected. !important ensures the styles override existing ChatGPT styles.

Step 5: Testing Your Extension

1. Open chrome://extensions/.
2. Enable "Developer mode."
3. Click "Load unpacked."
4. Select the chatgpt-molly-guard folder.

Test your extension in ChatGPT. If everything works, you'll see the red border and disabled submit button when you type sensitive words. Reload the extension using the circular arrow icon if you make changes.

Reload the extension after making changes:

Taking it Further:

• User Interface: Add a popup to manage the sensitive word list.
• Paste Handling: Detect pasted text for sensitive words.
• Contextual Override: Allow temporary disabling of the molly-guard.

Conclusion:

Building a Chrome extension is easier than you think! This simple "molly-guard" demonstrates how a few lines of code can significantly improve your online safety. Remember to consult Google's documentation for more advanced features.
