Google's NotebookLM is a new note-taking tool that allows users to consolidate information from various sources, including Google Drive documents, articles, YouTube videos, PDF files, and MP3 audio clips, into a single organized notebook. It utilizes Google's language model, Gemini 1.5 Pro, to analyze extensive text and generate outputs like briefing documents and study guides without requiring a premium subscription. The app features a bulletin-board style layout for easy usability and includes a chat feature with inline citations. One of its standout features is the Audio Overviews, which transforms notes into a podcast format with human-like hosts discussing the content. NotebookLM is currently available as a cross-platform web app and has recently shed its "experimental" label, though it does not yet have a dedicated mobile application.
