Gemini Notebook, formerly NotebookLM, is Google's AI research assistant that answers questions using only the sources you give it, with citations.
In plain words
You add sources such as PDFs, web pages, Google Docs, audio recordings or YouTube videos to a notebook. When you ask a question, it first finds the most relevant parts of those sources, then writes an answer with inline citations pointing back to them. It can also turn your sources into study guides, briefings, mind maps and audio overviews, which are spoken discussions of your material. Like any AI, it can still make mistakes.
A quick example
Imagine you upload your biology notes, two textbook chapters and a lecture video before an exam. You ask it to explain photosynthesis, and each point in the answer links to the exact passage it came from, so you can check it.
Where you'll meet it
- Studying and revising from your own notes.
- Summarising long reports or research papers.
- Turning documents into audio you can listen to.
