It's amazing how understanding can deepen when you're not just reading text, but also having it explained through visuals and audio. If you had a video with slides summarizing the key points of the material in front of you, along with narration, your learning and work would surely become much more fulfilling.

In this article, we will explain in detail the new NotebookLM feature that makes that "I wish I had this" a reality: "Video Overview Feature".
We will introduce everything from basic usage to specific applications that are useful in business and learning scenarios.

Note: The explanation regarding the use of generative AI, including NotebookLM, is just one example. Please ensure you verify the accuracy of the actual response results yourself.


What is NotebookLM?

What kind of tool is NotebookLM?

NotebookLM is a "research and thinking partner" that helps you with summaries, Q&A, and brainstorming based on the materials you upload. If you have a Google account, you can start using it for free right away from here.
Because the basis for its answers is limited to the materials you upload, you can control the source of the information yourself, which is a key feature that ensures high reliability. For example, you can use it to extract key points and differences from complex papers or lecture materials to deepen your understanding, or create an FAQ chatbot from your own company's documents. For basic usage, please also refer to this article.

NotebookLM continues to evolve every day, and recently, a "Video Overview Feature" has been added, where AI explains the content of the materials you upload. Let's take a closer look at this new feature.

Understand complex information easily with the "Video Overview Feature"

The "Video Overview Feature" is a function where AI automatically creates an explanatory video with narration based on materials you upload, such as PDFs, websites, or YouTube videos. You will be able to intuitively understand the content of complex reports or difficult papers that were previously hard to follow through text alone, just like watching a seminar video.

For example, for thick reports, specialized papers, or complex technical documents, the key points are organized with slides and narration, making it easier to grasp the arguments and causal relationships.

Note: This feature is not supported on the NotebookLM mobile app.

Easy 3-step process you can try right away

The usage is very simple, and it can be completed in 3 intuitive steps, from uploading materials to generating the video. Let's look at them one by one.

Step 1: Create a new notebook and add materials (sources)

First, create a new notebook in NotebookLM. A notebook is like a workspace for organizing information on a specific theme.

In NotebookLM, the following types of materials can be uploaded:

Document files: PDF, Google Docs, Google Slides, text files (.txt), Markdown files (.md)
Web content: Web page URLs, YouTube video URLs (Note: only videos with subtitles are supported)
Audio files: MP3, WAV (converted to text via speech recognition)

You can upload by dragging and dropping files or using the "Select files" button. You can also upload multiple materials at once, and NotebookLM will automatically integrate and analyze the content.

Also, even if you don't have materials on hand, you can search for relevant information using the "Find sources" button in the top right and import it directly. This allows you to gather materials based on a theme from scratch and create a video overview.

Note: As of September 2025, when using YouTube videos, only videos with subtitles are supported. Please note that videos without subtitles cannot be analyzed. For details, click here.

Step 2: Select "Audio Overview" in the Studio panel & customize to your preference

Once you have finished adding your materials, select "Audio Overview" in the "Studio" panel on the right side of the screen to start generating the audio.

💡Tip
Instead of just waiting for the generation, you can use the "Customize" feature to create audio that better suits your goals. Click the icon in the top right of "Audio Overview" and select "Customize." You can provide more detailed requests on what kind of audio you want NotebookLM to create.

For example, it is convenient to have a template for instructions (prompts) like this.

Based on the uploaded materials, create a summary audio in a story format ("Background" → "Argument" → "Evidence") that must include the following:

【Essence of the Source】: The most important points and conclusions of the material
【Purpose and Goal】: What the listener will understand and what actions or insights they will gain
【Focus Points of the Audio】: Content or issues you want to highlight (e.g., "Impact of XX," "New facts about △△")
【Target Audience】: (e.g., General public without specialized knowledge / Beginners in the field / All stakeholders, etc.)
【Tone/Style】: Friendly and easy-to-understand expression

Of course, there is no problem with freely adding or changing the items themselves.

In this way, just by telling it who the audio is for and what kind of content you want, NotebookLM will grasp your intent and adjust the structure and tone of the explanation.

Step 3: Listen to and utilize the generated audio

The generated audio is organized into key points in a slide format and explained with narration.
Furthermore, the completed audio can be downloaded in MP4 format or easily shared via a link.

1. Download and share
You can also download the audio directly to your device as an MP4 file.
Selecting the "Download" button will save the audio file in MP4 format. You can share the saved file via email, chat, etc.

2. Share the link
You can get a link to this audio overview from the "Share" button. If you set the sharing settings of the notebook itself to "Anyone with the link," anyone can easily listen to the audio even if they do not have a NotebookLM account.
※Currently, public sharing of notebooks is only available for accounts for general users.

Since you can choose the sharing method according to the scene in this way, information sharing and discussion within the team will become smoother.

You can use it like this too! 6 ideas for utilizing Audio Overview

From here, we will introduce 6 specific utilization ideas divided into scenes on how the Audio Overview feature will change our learning and work.

1. Making difficult materials easy to understand

Thick reports before meetings or government white papers filled with technical terms. "Even if I spend time reading them, they don't really sink in..." Have you ever had that experience? NotebookLM's Audio Overview feature can also help you understand the key points of such materials deeply in a short time.
For example, just by asking it to "make it understandable for an elementary school student" regarding a difficult technical white paper, you can create an explanatory audio to understand complex content in a "broken-down" way.

In this way, a major appeal of the Audio Overview feature is that you can generate explanatory audio tailored to your own level of understanding, rather than just summarizing.

2. Clearly "conveying" specialized knowledge to someone else

Explaining your own area of expertise or research to someone unfamiliar with the field is very difficult, isn't it? With NotebookLM, you can generate easy-to-understand explanatory videos from specialized papers and reports that even non-experts can grasp.
For example, if you create an explanatory video from an academic paper, you can use it as a new tool to widely communicate the background and significance of your research.

It is also useful when you want to look at your research content objectively or refine the structure of a conference presentation.

3. Turn your daily learning into your own personal "review content"

If you upload various materials you use for daily learning, such as lecture notes, reading records, and YouTube videos used for study, to NotebookLM, you can create "your own personal review videos" based on them.
Using technical explanatory articles as a source to create original study videos is one such way to use it.

If you turn parts you couldn't fully understand the first time or units you want to review again before an exam into videos, you could realize efficient learning by utilizing spare time, such as on the train while commuting.

4. "Unravel" complex technical documents with videos

Technical documents on the latest technology or highly specialized research papers. Even if you understand their importance, you often spend a lot of time trying to decipher them. By using the "Audio Overview" feature, you can convert them into easy-to-understand explanatory videos that hit the key points.

Complex logic and technical terms that are hard to follow with text alone can be understood more smoothly and deeply by inputting them visually through slides with narration.

5. Turn your strengths and experience into an attractive "introduction video"

You can also use the Audio Overview feature to organize your own career and personality to create an attractive "profile video."
For example, by summarizing the results of self-analysis tools or your resume and uploading them to NotebookLM, it is possible to generate an objective self-introduction video.

Not only is it useful for verbalizing strengths you hadn't noticed before or taking stock of your career, but you can also think of new ways to use it, such as attaching it to your job change portfolio.

6. Turn Deep Research results into easy-to-understand "explanatory videos"

It is also convenient to organize information you are curious about using Deep Research, import the results into NotebookLM, and create an explanatory video.

Like this case study, you can also use it to load the results of detailed research based on official information into NotebookLM and generate an original explanatory video. Being able to quickly create highly reliable content based on research is a major appeal.
