This tool generates a PDF file containing the main page and all sub-pages of a website that match a provided URL pattern.

📗The PDF generated by this tool is particularly well-suited for AI-based Retrieval-Augmented Generation (RAG) and Question Answering (QA) tasks.📗

🧳Portability: Combining multiple pages of a website into a single file enhances portability, making it easier to share and use the information.
🤖AI Integration: In some use cases, such as with Google NotebookLM and ChatGPT GPTs, providing a master dataset in PDF format helps in creating more efficient bots.
🖼️Visual Information Preservation: By generating results in PDF format, visual information like images is preserved, ensuring better recognition by multimodal models.

To run this software, you need to have Node.js installed on your machine. You can download and install the latest version of Node.js from the official Node.js website.

When running Puppeteer on Windows, you may encounter permission issues related to generating PDFs. To resolve this, you need to grant appropriate permissions. Follow these steps:

icacls %USERPROFILE%/.cache/puppeteer/chrome /grant *S-1-15-2-1:(OI)(CI)(RX)

• Navigates to the main page using puppeteer.
• Finds all sub-links matching the provided url_pattern.
• Generates a PDF for each sub-link using pdf-lib and merges them into a single document.
• Saves the final PDF file with a slugified name based on the main URL.

Note: The provided url_pattern should be a valid regular expression. If no url_pattern is provided, the tool will default to matching only links within the main URL domain.
