NotebookLM Clone: Turning Documents into Conversational Podcasts

Active voice makes writing clearer and more engaging. It places the subject at the forefront, as in, “Many students read the book” instead of “The book was read by many students.” Following this principle, we’ll explore the innovative NotebookLM clone, developed using ElevenLabs and OpenAI’s GPT-4o, which converts documents into interactive podcasts.

Overview of the NotebookLM Clone

1. Purpose

The NotebookLM clone transforms document formats—such as PDFs and slides—into short, engaging podcasts. These podcasts simulate conversations among multiple speakers, making information more captivating for listeners.

2. Technology Used

This clone combines:

• ElevenLabs’ Text-to-Speech model for realistic audio.
• OpenAI’s GPT-4o for conversational and informative content.

Together, they produce audio content that mimics natural human conversation.

3. Functionality

Users upload a document, and the system generates a podcast of about three minutes. It features discussions among two to five virtual speakers, making complex topics easier to understand.

4. Open Source Development

A developer has created Podcastfy, a Python package replicating NotebookLM’s podcast generation features. Podcastfy can:

• Generate conversational audio from documents.
• Pull content from websites or YouTube videos.

This versatility expands its utility beyond simple document conversion.

5. User Engagement

The clone fosters community involvement. Developers seek feedback from testers to refine and improve its usability. This collaborative approach enhances its development.
