Overview of Google NotebookLM
Google NotebookLM is an AI research assistant that works from the documents, websites and other sources you upload. It answers questions with references to your sources and can generate summaries and audio overviews. It runs on the web at notebooklm.google.com.
A free plan is available with limits on notebooks, sources and daily use. Paid tiers raise those limits, but sources disagree on tier names and prices, and some suggest the product has been renamed.
Files are processed on Google’s servers, and the tool has no offline mode.
