Meta has released a new open-source AI tool called NotebookLlama that is designed to allow users to create their own AI-powered podcasts. NotebookLlama, like Google's NotebookLM, converts various inputs (like PDFs, documents, or web links) into engaging podcast episodes with two AI-generated voices discussing the content. While NotebookLlama is not as polished as NotebookLM, it is free and customizable, giving users more control and adaptability. Meta plans to add more features, including processing web links and audio files, making NotebookLlama a viable alternative to Google's offering in the growing field of AI-powered podcast generation.
