NotebookLM: User guide with practical examples

You've probably heard of NotebookLM for its ability to create authentic podcasts from documentary footage.

However, NotebookLM is much more than that. It can quickly summarize complex documents, answer specific questions about them, and even convert them into summaries, study guides, or podcasts .

Another advantage is that we no longer have to switch between different windows or applications to ask questions, create summaries, or take notes — NotebookLM brings AI closer to content.

This guide will show you how it can make research and learning more dynamic, practical, and enjoyable.

What is NotebookLM?

NotebookLM is an AI-powered notebook developed by Google. It uses the documents you upload to train a specialized AI. The AI ​​in that notebook then becomes an expert on your documents, providing you with an invaluable resource tailored to your specific needs.

AI Priority Notes

Many note-taking tools have recently integrated AI features into their products. But NotebookLM is unique in that it is built entirely on AI. When you use NotebookLM, it's almost as if the AI ​​is a partner, reading your documents with you.

NotebookLM can highlight key points in dense documents, provide concise summaries, and help you learn material faster. It can also help you understand how different documents on the same topic relate to each other.

Below, you can see an example of how NotebookLM is used. On the left are some national and state (specifically Alabama) math education materials that the author has uploaded. On the right, NotebookLM has created a series of notes summarizing the information from those materials.

Your platform

Who among us hasn't copied text into ChatGPT and asked it to summarize it for us? While this is a great use case for ChatGPT, it's not perfect. The model will deviate from the document you uploaded and incorporate other ideas it has learned. And this effect is exacerbated the further your conversation strays from the copied text.

However, NotebookLM still focuses on the specific documents you've uploaded. When you upload a document—whether it's a PDF, Google Docs, or other text file—NotebookLM learns the information contained within it and adjusts its response based on those sources.

AI operates within your own content context, making its summaries and insights more relevant and accurate. You can be confident that you know where NotebookLM is drawing its information from.

You can see this clearly when uploading a unique work of fiction. Writers can use this product to query their own works to ensure clarity, coherence, and consistency. For example, an author has uploaded a fictional story that they requested ChatGPT to create. Because NotebookLM only retrieves information from uploaded documents, its response remains consistent with the fictional story.

Below, you can see that NotebookLM has created a summary, podcast, and suggested questions based on this fictional story.

Both automatically generated and handwritten notes appear on the notes page. Automatically generated notes always stay on topic regardless of the number.

Podcast feature

One of NotebookLM's standout features is its ability to create curated podcasts based on your material. Instead of struggling with a dense research paper, you can listen to two AI voices conversing and summarizing the content.

This could be a breakthrough for busy people or students who want to absorb information while multitasking. When testing this product, the author was able to exercise for 7 minutes while listening to a customized podcast describing the Federal Reserve's September 2024 Greylist. The article encourages you to try this feature if you haven't already.

While this is already a great feature, it's not hard to imagine its potential future applications. What if you could receive personalized news podcasts, custom book summaries, or even detailed recordings of your meeting notes? This could be a glimpse into the future of content consumption, where we listen to content tailored specifically for us.

Get started with NotebookLM

To start using NotebookLM, visit the NotebookLM website and sign in with your Google account.

After logging in, you'll see easy-to-understand instructions to get started with your first notebook. Click Create .

You will be asked to upload a document to start your notebook.

Images 5 of NotebookLM: User guide with practical examples

There are five different options for uploading documents:

1. You can upload files from your computer in PDF, .txt, or Markdown format.
2. You can link directly to a website using its URL.
3. You can copy and paste text directly into the notebook.
4. You can link to the Google Doc.
5. You can link to Google Slides.

Simply select the option containing the information you are interested in and link to your document.

There are a few limitations you should be aware of:

• You can upload up to 50 sources per notebook, with a maximum of 500,000 words per source.
• Its primary use is for text documents, so it doesn't currently work with Excel files.
• Larger documents may take longer to process. If you're working with dozens of files, you might want to prioritize primary sources to get details faster.

Once your document is uploaded, NotebookLM is ready to go.

Key features of NotebookLM

Let's explore the features of NotebookLM through our example document.

Notebook Association

When you upload a document to NotebookLM, the first thing you'll see is a dashboard called Notebook Guide .

Images 7 of NotebookLM: User guide with practical examples

This control panel contains:

• Automatically summarize the documents you have uploaded.
• Suggested questions you might want to ask, tailored to your document.
• Buttons to create several standard summary document types, such as a summary document or table of contents.
• A prompt for creating personalized podcasts.

Ask a question

One of the best parts of NotebookLM is that it lets you ask questions in natural language about the documents you've uploaded. There are three ways you can ask a question:

1. You can click on one of the suggested questions on the right side of the Notebook Guide.
2. You can start typing your own question in the bar at the bottom of the page.
3. You can click on View Chat in the bottom left corner of the page to go to the chat page and enter your question in the bar.

Whichever method you choose, it will take you to the chat page to answer your question. For example, type 'What are the five biggest takeaways from this document?' into the bar at the bottom.

Here, the author asked for the five most important points extracted from the document, and the AI ​​provided a bulleted list.

In addition to simply answering the question, NotebookLM also provides specific citations to show you where it got the answer from. These are displayed as small numbers in gray ovals next to the information. When you hover over or click on a number, the specific location in the document will appear. Let's click on number 3, for example.

When you click on reference number 3 in the answer, a 'Source guide' will open on the left side, showing the specific reference to that sentence in the answer. The specific location is highlighted. Very helpful!

Generate ideas

In addition to asking questions, you can ask the AI ​​to generate ideas for you on this chat page. For example, ask the AI ​​to brainstorm ideas to improve math education in the United States.

Images 10 of NotebookLM: User guide with practical examples

Here, the author has asked AI to help find solutions to the problems presented in the document.

Or how about something more abstract? Perhaps we need to create an awareness campaign and want a concise way to explain this material. Let's ask NotebookLM to write a haiku poem about the problem and its solutions.

Images 11 of NotebookLM: User guide with practical examples

Please note that this chat page only exists for a short time. When you close or refresh your browser, your conversation will disappear. If you wish to retain any part of the conversation, remember to save the responses as notes by clicking " Save to note" in the bottom-right corner of each AI response in the chat.

Notes page

When neither the note-taking instructions nor the chat window are open, the default screen is the notes page.

Images 12 of NotebookLM: User guide with practical examples

The default notes page currently has no notes. We need to fill in some notes there.

Let's start filling out notes on this page. There are two types of notes: handwritten notes and AI-generated notes.

Handwritten notes are notes you type yourself. To create a new note, click Add note at the top of the notes page. This will create a new blank note for you.

Images 13 of NotebookLM: User guide with practical examples

To edit this note, click on it. It will expand to the middle of the screen. You can change the title (default is New Note ) and add text to the note.

Images 14 of NotebookLM: User guide with practical examples

Notes are updated automatically as you type. After you finish writing a note, you can click anywhere outside the note to minimize it. Your handwritten notes are added to the notes page and labeled in green as " Written Note ." This helps distinguish them from notes written by AI.

Images 15 of NotebookLM: User guide with practical examples

Now, let's create a note using the AI. Go back to the conversation by clicking View Chat , and ask it to provide a step-by-step plan to improve math education over the next year.

Images 16 of NotebookLM: User guide with practical examples

If you scroll to the bottom of the answer, you'll find a "Save to note" button in the bottom-right corner. This will turn the AI's answer into a saved note.

Images 17 of NotebookLM: User guide with practical examples

Now, we'll see our handwritten notes from before and the AI-generated notes, both on the notes page. The AI-generated notes are labeled in blue as Saved Response .

Images 18 of NotebookLM: User guide with practical examples

The default title is "New Saved Note ," which we can change by clicking on the note. However, it is not possible to edit any other parts of this note.

You can see how we can quickly and easily consolidate all our thoughts into one neatly organized area in this section. And keeping the best chat results organized here is also very easy. Any unsaved conversations will disappear when you close the notebook.

Create Podcasts with NotebookLM

One of NotebookLM's most groundbreaking features is its ability to create custom podcasts with two AI voices discussing your document. This isn't just text-to-speech software – a podcast isn't a spoken transcript. Instead, it's a conversation between two speakers discussing the key points of the document. The format is truly like listening to a podcast. The voices sound natural and expressive.

Let's try creating a podcast about the NAEP documentation, for example. First, navigate to Notebook Guide by clicking the button in the bottom-right corner.

Images 19 of NotebookLM: User guide with practical examples

The podcast format is essentially an in-depth conversation. Simply click Generate below Audio Overview and wait a few minutes for the podcast to be created.

Podcast lengths are not fixed, but results typically range from 6 to 15 minutes. Some people receive podcasts as long as 30 minutes. Podcasts don't include every minute detail of the material. Instead, AI decides which parts are most important to cover and discuss.

Currently, there are still some anomalies with this feature. For example, in any podcast, the voice might offer examples of their personal life, say things like 'stay tuned next time,' or sometimes pause for commercials that aren't there. These anomalies will undoubtedly be improved as the product continues to develop.

You'll have a few options after creating your podcast. If you click the three dots in the upper right corner of the podcast rectangle, you'll see options to change the playback speed, download the file, or delete the podcast. If you delete it, you can create a new podcast.

Structured formats

NotebookLM not only helps you generate insights, it can also help you organize your notes into structured formats. Several new formatting tools in Notebook Guide make it easy to create FAQs, study guides, or timelines directly within your notebook.

There are two ways to do this. The first way is to select one of the five pre-set buttons at the top of Notebook Guide (FAQ, Study Guide, Table of Contents, Timeline, and Briefing Doc).

Images 21 of NotebookLM: User guide with practical examples

Let's try this in our example by clicking the FAQ button.

Images 22 of NotebookLM: User guide with practical examples

As you can see, this has created a new note on the notes page with the blue label 'Saved Response' . Inside this note is a curated FAQ section for government documentation. Like other AI-generated notes, the content of this note cannot be edited, but the title can be modified. For example, it would be renamed to 'FAQ' .

But what if we want a formatted note that isn't one of the five buttons listed in the Notebook Guide? We can always request specific formatting in the chat bar at the bottom. Let's ask for an interview scenario between a reporter and a mathematics education expert.

Images 23 of NotebookLM: User guide with practical examples

When you enter this request into the chat bar, it will take you to the chat page. You can scroll to the bottom of this reply block and click "Save to note" to create a formatted note. This is what the new note looks like after renaming it.

This process saves notes in the same way it saves answers.

This article encourages you to try requesting different formats. One format you particularly like is requesting emails to colleagues.
