LM Notebook, one of the most insane and powerful tools for learning anything. And no, that's not an exaggeration. Notebook LM was developed by Google and uses the same models as Gemini, which is Google's artificial intelligence, but it works in a different way. Its development was focused on working with more sources than we normally use in GPT chat or Geminário. What do you mean, Karine? Let's go. If you take a big book, then put a giant PDF and a web font, a YouTube video, for example, inside the GPT chat, it's quite possible that it will start hallucinating. What does this mean? It starts giving you answers you weren't expecting, because it has nothing to do with the content you put in, because it ca n't read everything you put in there. And furthermore, it is not restricted to just these data sources, but to all the knowledge it has within its model. This also happens with Gemini, Cloud, Grock and other tools that all have a specific context window. For you to better understand what this is, it is how much it can retain in memory and consult this memory to bring these results. And they are all also generative AI in its purest form. they will generate data and sometimes that data will be more erroneous than normal. So the LM notebook was actually created for you to do research and development on more academic subjects, more in-depth and with more assertiveness from different sources, because it can read more words than normal, since it is more restrictive to actually absorb those sources that you put. So, in short, Notebook LM is for those who can't stand so many AI hallucinations, for when you have a lot of information in different formats. So, you have a PDF, a book, a website, a YouTube video, an audio, and so on. And you want to transform all this information, which is very varied, into something cohesive in the end: an article, a scientific paper, or an understanding of a subject from these sources. And best of all, it 's free and I'll leave the link here in the description of this video. Now that you know what it's for, let's learn in practice how it works. When you open the notebook, LM will ask you about new sources you can add. I'm going to close this window because I want to show you back here how these panels work and then we'll come back to that window. Up here I can put the name of my notebook and we will search in this video for the meaning of life. I want to try to understand this and I will provide sources about this from philosophy. Below we have three large panels. In this first one, you will add fonts. In the second, you will chat with these sources, just like you do in GPT or Gemini chat. And thirdly, you can generate content from that source. Let's start adding sources here. I'll click on the add button and I can do the files, in this case PDF, audio, MP3, search directly from Google Drive, since it's a Google tool. also place links or paste text. Since I have a Google pro account, I can add up to 300 fonts. At the end of the video I talk about the free limits, which are also quite large. I want to start by adding a PDF font. I'm going to select the file and I'm going to bring up this manual by Epiquitetus, who is a stoic philosopher. Meditations of Marcus Aurelius. I selected the control here so I could click on multiple selections and Ryan Holiday's historical diary, which is a book on historicalism as well. I'll click open and these fonts will be inserted. All three will be there and they are very large sources. After all, these are all books. But I don't want to end with just these sources. I'll also add some YouTube videos. So let's click add here. I'm going to put this one from the new Acropolis with Professor Lucia Helena Galvão talking about Plato. Conttrl C on YouTube. I came back here. I'll select the YouTube button, paste it here and insert it. Let's add more. I want to give the LM notebook some work here. I'm going to a philosophy platform at Stanford University and I want it to be based on this paper on existentialism. I went back to my LM notebook and I'm going to paste a link to a website, this one first and then also one by Jean Paul Sarth that talks a lot about existentialism, which is one of the themes we're going to address here in the meaning of life. So, I pasted these two URLs, I'm going to click insert and they're going to be pasted there as well. Over there, he showed me a collection of these texts, but I want to explore each of them specifically. So, I'm going to select this one, what Plato has to teach us. I can explore the information from this specific source and analyze the summary and main themes about this video above. If I see that this video was not that relevant for this type of research, I can come back here, closing the source views and simply removing it from the entire evaluation that I will do here within the conversation along with the LM notebook. So if I uncheck it like this, it will be ignored. Down here, I can ask what the meaning of life is. I 'll send it and it will read all this information and have less hallucinations than if I imported all these files into the GPT, Gemini chat and made them analyze all this information. He is starting to generate and all his citations and sources based on these excerpts that were highlighted have the exact passage from which he made this summary for this excerpt. So, in this case, he is saying that for historicism, the meaning of life is deeply rooted in the practice of a philosophy that seeks to improve human beings and achieve a good life. If I click on that one, it will guide me to the source and put exactly what was the excerpt that it summarized to put that specific sentence. And in this case, look, it was from CECA. I'll close this quote and he'll start to elaborate on the rest with all the sources I gave. If you have a Geminiik pro account, it also gives you access to the LM notebook. Here in the settings, you can define the conversation style, whether it will be an analyst, a guide, or personalized. I can determine the style down here. Let's say it's going to be an analyst and the size of the response. I'll want it as long as possible. Let's click save. And I'm going to choose one of those predetermined answers that he has down there about how Stoicism defines happiness. I clicked on this suggestion and after taking a little while, it doesn't take that long, but it can go between 1 to 2 minutes, I cut the video here, he starts to elaborate this answer and you can see that it was much longer than the previous one. If I liked this answer, I have to save it here in the observations, otherwise I will lose it, because the conversation history is not stored, because that is not the purpose of the LM notebook, to keep various information here that was explored. If you liked it, you can simply click save in the notes and it will generate a rating. And then you can talk more and more, generating notes and then create content, an article, a scientific study or anything else you want to create with these notes. Now, look how interesting, down here, when you start editing, I'm going to ask him about the history of Brazil, which is information that isn't in those sources over there, but after all, it is an AI. Will she give me that answer? I'll send it and let's see if she'll hallucinate, if she'll say something that doesn't make any sense for this notebook here, look. The sources provided deal primarily with Stoicism, its philosophers, and applications to everyday philosophy. They have no information about the history of Brazil. Now you understand what to actually use the LM notebook for. They are for more precise and more serious developments. And speaking of that, if I want to put other information here besides these sources that I predetermined, I can also use the LM Notebook to discover those sources. So, I'm going to click here. I can write what the meaning of life is and send it to him to search for this information. Of course I'm not going to choose all of these because there are Wikipedia sources. So I'm going to remove this selection and let's suppose I want to add this philosophy class here, the scientific study by Celo, which I know is a relevant source of scientific research. And then I could choose others too. I will import and I can increase my sources and start studying and exploring from these new sources. You might be thinking, "Oh, Karine, so that's it? I can talk to the sources?" No, remember I showed you these two panels here. This last one is missing and you'll be impressed now. With the LM notebook I can create an audio summary, a podcast on this subject and it generates. I can click here and down there it will start processing and generating this audio. I can also generate a video summary, which he will make animated and with voiceover, a mind map about this information and these sources and also reports with a summary document, a study guide for me to study on this topic, frequently asked questions and a timeline. I'll choose all of these for him to create. summary document, study guide, FAQ, and timeline. He already created the map up there, look. Let's see if it generated below. No, it 's still generating. We can wait a little bit. In the meantime, I'll show you its other capabilities. Let's assume that I also liked this text above . I'll save it here in the observations. So here on the side I will have two observations in total that I selected by exploring this file, which is historical happiness and one more down there that I had created. I can click on these three dots and transform it into a font, that is, it will be used here because, after all, this font was generated from these files. or convert all notes into one font. I will select this option. And down here he grouped all the notes into just one single, quote-unquote, file. Now that it's starting to generate some of the things I asked for, let's see. The timeline. I selected it, and it showed me a detailed timeline of major events and concepts, classical antiquity, talking about philosophy in general. So I created a timeline of all these sources that I have. And look at this work and it has dates, like all the mentions of philosophers and events that these sources here generated. Beauty? I'll come back here now. Let's understand this study guide on stoicism, existentialism and the search for meaning. He created a review guide for understanding the materials provided and first started with the meditations of Emperor Maco Aurélio, putting all the information about what is in the book, the practices. Then, existentialism based at Stanford University. Yet another summary, nihilism, preceding existence of essence, freedom. Then, search for meaning by Vittor Fruckle down here and so on. And it didn't stop there. Look, he even created a 10-question quiz for me to answer, like, what does the famous historical phrase existence precedes essence mean? And down below he gave me a quiz answer key to that question. Dude, can you understand any topic like that? Below, five questions in essay format, which is a way of studying scientifically. Glossary of key terms, amorphate, aquesis, ataraxia and non-para. If this detailed information wasn't enough. Coming back here, we have a summary document. I'll click on it. And then this document simply summarizes all of these sources. Now let's look at the frequently asked questions we generated. What is Stoicism and what are its main disciplines? And answer later. What is the main difference between what we can and cannot control? How does Suoiism approach negative emotions like anger? How important is guiding reason? And here below it already gets to where I want to address, how it relates to purpose and meaning in life. Let's go back and see the other generations he gave. Here we have that mind map, Toicism, ancient philosophy, foundation, popularity, existentialism is the parallel, main themes. If I select one of those buttons for death anxiety, freedom, meaninglessness, it will search within those sources and develop exactly on that topic. And then I can search for that topic, save my notes and create my own file. But I saved the best for last. Look what he generated here. A video about philosophy. I will select play. If I had provided more specific sources about the meaning of life, he would have been able to make it more specific. But as I put more random, he didn't. I'm going to press play. Here it is in English because my default is English, but you can use your LM notebook default for Portuguese. Put it further forward. Look at this narration [Music] and this information he presented here. Simply amazing. It's a 7 minute video. This is so amazing. I'm going to close it so we can now look at the audio. Play. Hello, welcome to our latest conversation. It has Portuguese from Portugal. They feel that the world is a bit chaotic, full of noise, information everywhere. Uh-huh. It's a common feeling, I think. Well, a lot of people feel this pressure. It's a 20-minute podcast about philosophy for chaos. He even created a name for this episode of the podcast. It calls for stoicism, existentialism and the search for meaning in uncertain times. Man, this is the best tool for learning specific subjects. And in this case I'm doing it about the meaning of life, but you could easily import multiple earnings reports from the 50 largest companies in the world. Here we have more than 90 sources and he can make a summary about the economy in general and make a video about these 91 sources. If I click here, it will teach me about all of these sources in just one video. to summarize, 75 billion were what these companies generated in the first quarter of 2025 in this case. And now do you understand what the LM notebook is for? Now let's look at the limitations of the free and pro accounts. In the free version, you can create up to 100 notebooks, each with up to 50 sources and up to 500,000 words each. And there are daily chat query limits of 50 and three audio generations and three video generations. With the paid Pro account, you also get access to Gemini when you upgrade to Pro. This limit increases to 500 notebooks, 300 sources, 500 daily chat queries, 20 audio generations, and 20 video generations. If you're not using this tool yet, go ahead and use it.
