A walkthrough for teachers and students: adding sources, checking citations, and the study features that turn a reading list into review material.
NotebookLM is a research and study tool that answers only from documents you give it. Google renamed it Gemini Notebook in July 2026 and called it "the same standalone product," so if you learned the old name, nothing you knew has changed except the label and the web address.
That one design decision explains everything else about how to use it. Google's education page describes it as "grounded only in the information you provide." It is not a chatbot with the whole web behind it. It is a tool pointed at your pile of sources.
Practically, that means the quality of what you get out is set almost entirely by what you put in. Most of the skill in using it well is source selection, not prompting.
Start by uploading the material the answers should come from. For a teacher that is usually the readings, the textbook chapter, the standards document and your own slides. For a student it is lecture notes, the assigned papers and the course reader. For a faculty literature review, NotebookLM covers only the synthesis step; see which AI tool fits each step of a literature review. If you still need to find the papers, start with which AI tools search scholarly papers.
Be deliberate about what you leave out. Because the tool answers only from your sources, one outdated syllabus or a draft you abandoned will get quoted back to you with the same confidence as the current version. Removing a bad source improves the output more reliably than rewording a question.
Google also offers ready-made notebooks built with OpenStax, the free peer-reviewed textbook publisher, covering Biology, AP Biology, Chemistry, Psychology, Introduction to Business and Principles of Management. If you teach one of those, that is a faster start than uploading a book yourself.
Every answer comes back with in-line citations pointing at the source document. Google lists this as a core feature, and it is the single most useful thing about the product for classroom work.
Use the citations rather than admiring them. Click into two or three on any answer you plan to rely on, and confirm the cited passage actually says what the summary claims. Grounding reduces invention. It does not eliminate misreading.
This is also the limit worth explaining to students: the tool can be wrong about your sources while still citing them, in the same way a rushed reader can be. Citations tell you where a claim came from, not that it was understood correctly.
Once sources are in, the tool can turn them into finished formats. Google's education page lists what it produces from your uploaded material:
A code-execution capability arrived with the July 2026 update, running in what Google describes as a secure cloud computer, which extends the tool into data analysis rather than only reading text. Note the tier gate: Google announced it for AI Ultra users and Workspace business customers with the relevant access, rolling out to Pro users on the web, so it is not part of what a free account gets.
Google shipped a set of features aimed specifically at students, and they change the tool from a summarizer into something closer to a study partner.
Flashcards and quizzes are generated straight from your documents, with topics and difficulty you can adjust. Each item has an "explain" action that opens a fuller overview with source citations, so a wrong answer becomes a short lesson instead of a dead end.
The Learning Guide is the most interesting of them, and the easiest to misuse. Google describes it as asking "probing, open-ended questions" and helping you "break down problems step-by-step" rather than giving direct answers. Students expecting an answer machine often abandon it in the first minute because it does not behave like one.
Audio Overviews come in three shapes, and picking the right one matters more than students expect. Brief is a single host giving a short summary. Critique puts two hosts on your work offering constructive feedback. Debate has two hosts argue different perspectives on the material.
Critique and Debate are the two worth teaching. A student revising an essay learns more from a Critique pass over their own draft than from another summary, and Debate surfaces the counter-arguments a one-sided reading of the sources will miss. Most students only ever try Brief, which is the least useful of the three for anything beyond catching up.
Reports have a redesigned set of formats, including a Blog Post option, and the tool suggests formats based on the theme of your sources. You can define your own format too.
The notebook and the main Gemini app now share material. Google says a student's "notebook's sources are seamlessly integrated across Gemini app and NotebookLM," which means you can reference past chats and generate flashcards across the two.
The practical rule for deciding which to open: use the notebook when the answer must come from specific documents, and the Gemini app when you want general help that is not tied to a reading list. Our side-by-side comparison works through the harder cases.
One caution on the first workflow. Anything you upload becomes the basis for what the tool tells your students, so check your school's rules before uploading copyrighted textbook scans or anything containing student data.
It will not tell you things that are not in your sources, by design. That is the feature, and it is also the frustration for anyone expecting general knowledge. If your reading list has a gap, so will every answer.
It is not a plagiarism check, a grading tool, or a substitute for reading the material. And an Audio Overview of a chapter is a summary of a chapter. A student who listens instead of reading has covered the shape of the argument, not its detail.
If your school has not enabled it, students cannot open it regardless of plan, since Google says availability across ages depends on the administrator turning it on. Cost is rarely the blocker; our pricing guide covers what is free and what the paid tiers add.

Upload the documents the answers should come from, ask questions and check the in-line citations against the source, then generate the format you need: a study guide, quiz, flashcard set, mind map, Audio Overview or slide deck. Source selection matters more than prompt wording, because the tool answers only from what you give it.
Yes. Google renamed it in July 2026 and described it as the same standalone product, with the old address redirecting to the new one. Most people still search for NotebookLM, so both names appear throughout this guide.
The Learning Guide asks probing, open-ended questions and helps you break a problem down step by step instead of handing over a direct answer. Students expecting an answer machine often quit it early. It is closer to a tutor working through a problem with you than to a search box.
Brief is a single host giving a short summary. Critique has two hosts give constructive feedback on your material. Debate has two hosts argue different perspectives. Critique is the most useful for revising a draft, and Debate surfaces counter-arguments, but most students only ever try Brief.
Yes. It generates both from your uploaded documents, with adjustable topics and difficulty, and each item has an explain action that gives a fuller overview with citations. Google's help documentation notes you need edit access to a notebook to generate or delete them.
Yes. Grounding in your documents reduces invention but does not prevent misreading, so an answer can cite a real passage and still summarize it incorrectly. Click into two or three citations on anything you plan to rely on and confirm the cited text says what the answer claims.
Google says students under 18 get a distinct product experience with extra guardrails, and that availability across ages depends on a school administrator enabling it. If it will not open for your students, that is usually an admin setting rather than a billing issue.
Feature descriptions come from Google's own education, help and announcement pages and are current as of August 2026. Features and availability change quickly, so verify current behaviour in the product and check with your school administrator before classroom use.
