Google on Tuesday announced Short Video Overviews for NotebookLM, its AI-powered research assistant and knowledge base builder. The feature, as the name suggests, allows users to generate concise videos leveraging AI. The Mountain View-based tech giant says it can summarise uploaded sources in a minute using narrative explanations and educational animations. The feature builds upon Google’s steady transformation of NotebookLM from a simple AI-powered research assistant into a more versatile learning tool in recent months.
