NotebookLM

NotebookLM is an AI-powered research and writing tool developed by Google that helps users understand and analyze information from various sources. It acts like a personalized research assistant, allowing users to upload documents (like PDFs, Google Docs, website URLs, and more), and then ask questions, get summaries, and explore connections within the content. The difference between NotebookLM and other popular AI models is that NotebookLM will only train itself from material that you upload. 

Therefore, all generated content can be age and stage appropriate.
