Natural Readers Downloder

Overview

This Tampermonkey user script extracts, indexes, and automatically downloads blob: URLs from media elements (e.g., audio, video, images) on a webpage. The script is particularly useful for sites that dynamically generate and use blob: URLs, such as Natural Readers.

Each blob: URL is captured and downloaded sequentially with a numbered filename, such as file_1.mp3, file_2.mp3, etc.

Features

• Automatically detects blob: URLs created via JavaScript's URL.createObjectURL method.
• Monitors dynamically added media elements (e.g., <audio>, <video>, <img>, <iframe>, <source>) on the page and captures their blob: URLs.
• Adds a "Download All Blob URLs" button to the webpage that, when clicked, downloads all captured URLs in sequence.
• File naming convention: file_1.mp3, file_2.mp3, etc.

How It Works

1. The script hooks into URL.createObjectURL to capture any dynamically created blob: URLs.
2. It scans the webpage for media elements that use blob: URLs.
3. A button is added to the page to download all captured blob: URLs in sequential order.

Usage

Customization

You can customize the file extension or modify the filename by editing this line in the script:

a.download = `file_${index}.mp3`;

You can change .mp3 to another extension (e.g., .png, .wav) depending on the type of media you're downloading.
