AI Blocker Chrome Extension

The AI Blocker Chrome extension allows you to block or unblock access to specific AI websites. It detects when you're visiting restricted AI websites and prevents access by injecting a custom "blocked" page. You can also unblock these websites using the extension's interface.

Features

• Block access to specific AI websites (like ChatGPT, Claude, Gemini, and more).
• Custom "Access Blocked" page is shown when a restricted website is visited.
• Unblock websites and reset the page with a simple click.
• Works on both new and existing tabs.

Supported Websites

The extension blocks the following AI-related websites by default:

• chatgpt.com
• claude.ai
• gemini.google.com
• perplexity.ai

You can easily modify the list by adding or removing websites in the myurls array.

Installation

Step 1: Download the extension code

Clone or download the source code from this repository.

git clone <repository_url>

Step 2: Load the extension into Chrome

1. Open Chrome and go to chrome://extensions/.
2. Enable Developer mode (toggle switch in the top right).
3. Click Load unpacked and select the directory where you saved the extension files.
4. The extension should now appear in your list of extensions.

Step 3: Use the Extension

• Click the extension icon to open the popup.
• Use the Block button to start blocking AI websites.
• When blocked, the button will change to Unblock.
• Click Unblock to restore access to previously blocked websites.

How It Works

The extension uses the chrome.tabs API to monitor tab creation and updates. If a tab’s URL matches one of the AI-related URLs (either through exact matching or partial matching), the extension will block access to the website by:

• Injecting a custom "Access Blocked" page using chrome.scripting.executeScript.
• Storing the blocked tab’s ID in chrome.storage.local to remember blocked sites.

When unblocking, the extension:

• Reloads all tabs that were blocked.
• Resets the page content to its original state.
• Removes the tab ID from storage.

Code Overview

• background.js: Manages the core functionality, such as blocking and unblocking tabs, interacting with the Chrome APIs (tabs, storage, scripting), and handling messages between the popup and the background script.
• popup.html: The interface displayed when you click the extension icon. It contains a button to block or unblock AI sites.
• popup.js: Handles the button click events and communicates with the background script to block/unblock AI websites.

Development

To modify the extension or add new features:

1. Clone the repository.
2. Make changes to the JavaScript files.
3. Test your changes by reloading the extension in chrome://extensions/.

Suggested Improvements

• Add a customizable list of blocked websites through the popup.
• Include more advanced blocking options (e.g., blocking based on content type, user-defined categories).
• Provide user feedback on which sites are currently blocked.
