How to Use

Upload documents, websites, and videos to create AI-powered notebooks for summarizing, asking questions, and generating podcast-style audio overviews. (app_description)

Getting Started

Source: app_description_and_user_feedback_noted

  1. Download and open the Google NotebookLM app.
  2. Create a new notebook for a specific topic or project.
  3. Upload your sources, including PDFs, YouTube videos, or text, directly into the notebook.
  4. Ask the AI questions about your sources, or generate an Audio Overview by selecting the 'Audio Overview' option.

Key Features (from app listing)

Source: app_description

  • Upload and manage sources from PDFs, websites, YouTube videos, and text.
  • Ask questions and receive answers with in-line citations from your sources.
  • Generate podcast-style Audio Overviews for listening on the go.
  • Background playback and offline support for Audio Overviews.
Pro Tip: To make the most of the Audio Overview feature, start by uploading a single, well-structured PDF to see how the AI hosts break down the material before adding multiple complex sources.

This tip is responsive to user feedback indicating that managing multiple sources can be difficult due to the lack of folders, and the app description highlights the Audio Overview feature as a primary way to 'transform what you uploaded' into a digestible format.

Pros & Cons

Based on analysis of Google Play user reviews

Pros

    Theme 'Audio Overview quality' independently appeared in 2 recent_reviews. Review #1 praises the ability to get game synopses and explanations. Review #2 states the Audio Overview feature alone makes the app 'worth it,' using the phrase 'genuinely rich.'

    Evidence (2)
    “Great way to get a video game synopsis, have metaphors in a movie plot explained... If the only feature was the podcast-like reviewing, it would still be worth it. I'm blown away by the genuine richness of that feature.”

Great way to get a video game synopsis, have metaphors in a movie plot explained. Can choose length of podcast that gets created. Max length is only 20 minutes unfortunately, and the app doesn't remember where you were last so you have to remember where you were last. These are the only 2 negatives I can think of. Great for car rides, entertainment while mowing the lawn or really anything mundane.

If the only feature was the podcast-like reviewing, it would still be worth it. I'm blown away by the genuine richness of that feature. My only wish is that there was some kind of "word processor" where you could write directly in the notebook - even if it was just a simple notepad thing. But I understand that's not the purpose. Overall very cool.

The idea is brilliant, but the app itself needs improvements, when adding sources or generating any quiz/flashcards you should be able to rename them too, so you can differentiate which source is what, and the generated quiz is based on what source. Also, when uploading multiple sources, and unchecking one source it shouldn’t include it in the generated quiz, but it still includes whatever you check or uncheck. Good job guys, and I will be more than happy to help you review/improve when needed.

This app is really useful for studying key concepts. I really like this app, especially since I can pull it out of my pocket. However, they don't accept PowerPoint, which is kinda disappointing, especially if it's just a Word document. Also, sometimes there are some bugs when trying a slide deck and graphics, but they don't work. Overall, I like this app, and I hope they add support for things I like, such as PowerPoint.

It's getting there, but it's nothing special right now. The fact that every single thing needs added as it's own "source" is ridiculous. No groups or subfolders. I get it, it's because they only allow so many "sources" based on what tier you pay for.. But it makes it pretty useless for extensive research. The Featured Notebooks that we can't turn off make me feel like I'm using Bing and being force fed news articles I don't care about. This isn't a notebook so much as an unorganized list.
