What is Open NotebookLM?
Open NotebookLM is an open-source AI tool that uses the latest open-source AI models, such as Llama 3.1 405B, MeloTTS, and Bark, to convert PDF documents into podcast-style audio content. The tool is suitable for users who want to convert written information into an auditory format, such as students, researchers, and podcast producers. By analyzing document content, it generates natural and fluent dialogue, outputting as MP3 files for users to consume written information auditorily. Technically, Open NotebookLM relies on open-source Large Language Models (LLM) and Text-to-Speech (TTS) models, such as Llama 3.1 405B and MeloTTS, supporting multiple languages and providing the ability to customize intonation. Users upload PDFs via a Grado-based interface, select a dialogue style, and generate audio.
