Hey there,

This week I wanted to talk about one of my favorite AI tools: NotebookLM. This standalone, Gemini-powered tool is an AI research assistant that instantly becomes an expert on the sources you upload. This means that instead of pulling from unreliable internet sources or outdated training data like a traditional chatbot, it focuses solely on the documents you choose to share. This week we’ll explore its core differences, how best to use it, and look at some of NotebookLM’s best features. 

What makes NotebookLM different 

The thing that sets NotebookLM apart is that every response is source grounded. You get to upload your files and everything it tells you comes directly from those sources. In fact, NotebookLM won’t answer questions that are unrelated or not mentioned in your sources. Every answer also includes a citation that goes directly to your source so you can double check information or continue researching the answer on your own. As you’d expect, this effectively eliminates the potential for hallucinations and makes it the perfect tool for breaking down massive amounts of data or content for written reports and research papers.

NotebookLM supports multiple source types so you can upload just about any file type. PDFs, Google Docs, Word files, spreadsheets, images, websites, and even YouTube videos. Another difference is that instead of just the standard question and response loop, you can create unique outputs like Audio and Video Overviews.

The features worth your time 

NotebookLM can generate a ton of helpful outputs, but several of them are worth covering here.

Audio Overviews are the feature that first made NotebookLM popular. They can turn your sources into a podcast style output where two hosts talk through your files and help make the material more engaging and digestible. This feature also includes an Interactive Mode that allows you to speak directly to the hosts. By asking questions and guiding the conversation, you can better understand large amounts of information.

Video Overviews are the visual version. Similarly to Audio Overviews, this feature creates an engaging output that consists of a narrated slideshow with unique visuals that pull information straight from your documents. These are great for visual learners.

The Quiz and Flashcard features fit perfectly for learning. By uploading the text or lesson, you can get a custom, interactive learning experience. The Quiz feature doesn’t just create a static multiple-choice quiz, but will instead give you hints and explainers for each question.

Deep Research brings the ability to find relevant sources for your notebook. This feature is focused on finding and suggesting sources that will complement or contradict your existing materials. This is a great resource for when you just start a new notebook and may not have tons of sources yet.

The Notes feature is simple but highly effective. You can save anything NotebookLM creates or write your own notes, and keep them inside your notebook. This ensures that as you work in your notebook, you can pull out the most important information and store it separately as opposed to losing it to your never-ending chat history.

These aren’t the only tools that NotebookLM offers, Mind Maps, Reports, Infographics, and Slide decks can also be created.

A few real ways to use it

The easiest way to understand NotebookLM is to jump right in. You can drop in a stack of research papers or a dozen technical reports and quickly ask questions or pull out the most important information. Alternatively, you can use NotebookLM as a resource for learning. By finding a dense academic paper and uploading it to a notebook, you can then create flashcards and quizzes for each chapter. And when there is a long piece of content that you want to absorb but you don't have the time to sit down and read it, you can listen on the go using Audio Overviews. You can also just use NotebookLM as a more traditional chatbot and take advantage of the grounded responses to effectively work with your own data or content. At the end of the day, NotebookLM is a flexible tool that can be utilized for a number of different tasks.

My Thoughts

NotebookLM stands out to me because it's clear about what it's meant to do. So many AI tools overpromise and underdeliver, but NotebookLM is different. At its core, this tool is meant to give grounded responses based only on the sources you share. These responses come in a variety of forms but are trustworthy and evidence based. If you go in expecting a ChatGPT clone then you’ll be disappointed, but if you want to work with 50 files in one notebook to pull accurate, evidence-based answers then NotebookLM is the perfect tool. Of course, the only way to know for sure is to create your first notebook!
