Google NotebookLM

Turn your sources into a research workspace

Google NotebookLM helps you work with information you bring to it. Add materials such as PDFs, web pages, YouTube links or text, then ask questions and get summaries based on those sources. It suits students, researchers and anyone sorting through a collection of documents who wants to find key points without rereading everything from scratch.

Ask questions and check the answers

NotebookLM’s responses are grounded in the material in your notebook, rather than being presented as general-purpose answers. It can include citations that point back to the source, giving you a way to check what a response relies on. That makes it useful for comparing notes, reviewing a long reading list or getting oriented in unfamiliar material. As with any AI-generated summary, it’s worth checking the original source before relying on important details.

Listen as well as read

The app can turn source material into an audio overview presented as a conversation between AI voices. This offers another way to review a topic when reading isn’t convenient. NotebookLM is still built around your sources: the audio feature is a format for exploring that material, not a substitute for deciding whether its claims are relevant or complete.

For focused study and research

NotebookLM is a productivity tool for people who want to organize source material and explore it through summaries, questions and audio. It is less suited to general note-taking without a source-based research task in mind. The Android app comes from Google LLC and has a 4.82-star rating from about 132,000 reviews, with 10 million-plus installs.
