NotebookLM (Google NotebookLM; LM short for "Language Model") is a research and note-taking online tool developed byGoogle Labs that usesartificial intelligence (AI), specificallyGoogle Gemini, to assist users in interacting with their documents.
NotebookLM is known for its Audio Overviews feature, which generates podcast-like discussions about the uploaded content. Google describes NotebookLM as a "virtual research assistant".[4] The team building the product includes popular science authorSteven Johnson and product manager Raiza Martin.[5][6]
NotebookLM was first introduced in May 2023 under the experimental nameProject Tailwind, presented as an AI-driven notebook capable of learning from user-provided documents.[7] In 2024, Google rebranded the tool as NotebookLM and began rolling it out more broadly to researchers, students, and enterprise testers.[8]
On October 17, 2024, Google removed the software’s “experimental” status, signaling its transition into a stable product.[9] In December 2024, the company launched a paid tier namedNotebookLM Plus for enterprise customers and Gemini Advanced subscribers via Google Workspace and Google Cloud.[10]
Throughout late 2024 and early 2025, Google continued expanding NotebookLM’s availability and feature set. On February 10, 2025, Google extended NotebookLM Plus to individual users through the Google One AI Premium subscription plan, following its initial enterprise-only launch in December 2024.[11]
NotebookLM can generate summaries, explanations, and answers based on content uploaded by users. It analyzes the provided sources to extract key ideas and present them in a simplified and structured manner.[12]
In addition to text files, NotebookLM can processPDFs,Google Docs, websites, andGoogle Slides.[12] It can also analyze YouTube videos from their transcripts.[13]
The "Audio Overviews" feature,[14] released in September 2024, converts documents into a conversational, podcast-like discussion between two AI hosts. The feature received attention for its ability to condense complex or lengthy documents into accessible audio summaries.[4][15][16]
In December 2024, Google introduced interactive Audio Overviews, allowing users to join the AI-generated conversation by tapping the “Join” option. Users can ask questions directly and participate in the discussion with the AI hosts.[17]
In 2025, NotebookLM added a new Video Overviews feature, which transforms document summaries into visual slide-style videos combining AI narration, images, diagrams, and structured explanations.[18] Google later expanded both audio and video overviews to more than 80 languages.[19]
In early 2025, Google launched NotebookLM Plus, a premium version included in the Google One AI Premium plan. The upgraded tier provides higher usage limits, support for longer documents, collaborative notebooks, and enhanced output controls.[20]
In November 2025, NotebookLM added the features "Infographics" and "Slide Deck". These features, powered by Google's image-generation modelNano Banana Pro, allow users to visualize their source material as presentations or detailed infographics.[21][22]
The 2024Spotify Wrapped used this feature to generate podcast-style personalized overviews of individual listening habits.[23]
Initially intended for researchers, NotebookLM has also been adopted by companies and students.[12]
In 2026, journalist and formerNPR hostDavid Greene sued Google, alleging that NotebookLM’s AI podcast-generation feature reproduced his distinctive voice without permission, a claim the company denied.[24]
