NotebookLM: Optimal use of your information

We are bombarded with countless pieces of information every day: studies, internal reports, customer data, presentations - all important, all relevant, but hardly anyone has time to read and process it all thoroughly.
This is exactly where NotebookLM comes in: a tool that helps to efficiently organize, analyze and make use of large amounts of information.
What is NotebookLM?
NotebookLM is a digital research and writing assistant based on artificial intelligence . What makes it special: It works exclusively with the content you upload - be it a website, a PDF, a YouTube video or a voice message. So you don't get generic answers, but precise results based on your own data.
What can NotebookLM do?
- Bundle & analyze data: NotebookLM processes up to 300 sources per NotebookLM (notebook) - each with up to 500,000 words.
- Work directly with content: You can ask questions to your sources and receive precise answers with quotations from the original text.
- Generate content: Whether briefings, outlines, FAQs or audio summaries - NotebookLM quickly creates these documents based on the sources.
- Enable collaboration: Notebooks can be shared and worked on together. This is suitable for teams, onboarding or product documentation.

The most important functions of NotebookLM
- Upload different sources of information and interact: Upload a wide variety of sources such as websites, presentations, documents (Docs, PDFs), text, audio and YouTube URLs. You can manage up to 50 sources per notebook, with each source containing up to 500,000 words. After uploading, you can chat directly with your sources to get in-depth information.
- Content generation: Easily create different types of content, including audio overviews, briefing documents and outlines. Use ready-made prompts such as "study guide" or "briefing document" to get started quickly and efficiently.
- Insights and organization of information: Consult all your data sources simultaneously to gain valuable insights or dynamically generate new content. You can pin important findings or interesting facts directly from your sources.
- Collaboration: Share your knowledge and work seamlessly with others. Create notebooks with all relevant documents, for example for onboarding processes or product information, and share them. You can also assign access rights for adding or deleting sources to build knowledge together.
- Voice-over and subtitles: NotebookLM can create audio overviews from your uploaded sources, providing an additional way to convey information.
The most important advantages of NotebookLM at a glance
1. own content as a database
NotebookLM works with the sources you provide yourself - such as websites, PDFs, presentations, audio files or YouTube links. Up to 300 sources can be managed per notebook, each with up to 500,000 words. The tool analyzes your content directly - regardless of format or language - and provides specific answers based on this.
2. answers with sources
All results contain inline citations. This means you can immediately see where the information comes from - and can read it directly in the original if required. This creates transparency and prevents misunderstandings.
3. data protection included
Your data remains private. NotebookLM does not use it to train AI models, and no content is logged or viewed by third parties within Google Workspace or Gemini. This is particularly important for sensitive information.
4. quickly create insights and content
Whether summaries, outlines, briefings or audio overviews - NotebookLM quickly turns complex content into usable results. This saves time, especially in project preparation.
5. using knowledge together
Notebooks can be shared with others - for teams, training courses or product documentation, for example. Access rights can be defined individually so that it is clear who is only allowed to read or edit content.
6. output as audio in podcast style
Another highlight is the audio output: NotebookLM can output analysis results as an audible summary - in podcast style, for example. In the so-called "discussion mode", you can even ask specific questions about individual audio content. This not only makes working with extensive documents more efficient, but also significantly more flexible.
NotebookLM in practice: Selected use cases
- Sales: NotebookLM serves as a central knowledge base for sales meetings. Product information, price lists, case studies or meeting notes from previous contacts can be stored in a structured way and retrieved in a targeted manner. This creates individual documents that are tailored to the respective customer.
- Customer service: NotebookLM is suitable as a self-service platform for support teams. Frequently asked questions, technical manuals, support tickets and chat histories are linked together. This means that queries can be answered quickly and accurately - without long searches.
- Research & Development: Here NotebookLM helps to organize and link studies, patents and test documentation. It recognizes cross-references, supports the derivation of new hypotheses and facilitates the creation of reports or patent applications.
- Audit preparation: Instead of searching through folders, relevant documents - such as process descriptions, guidelines or training certificates - can be uploaded directly into NotebookLM. The system finds the relevant passages in case of queries, which makes preparation and verification much easier.
- Managers: NotebookLM supports decision-makers in preparing information. Market analyses, reports or personal notes can be stored centrally and summarized compactly before important meetings - with direct reference to the underlying sources.
- Market and industry knowledge: NotebookLM collects and analyzes specialist articles, studies, news feeds and patents. It recognizes patterns, detects trends at an early stage and summarizes relevant developments - ideal for well-founded assessments without time-consuming research.
- Personnel development: training materials, skills profiles and further training opportunities can be clearly managed with NotebookLM. This makes it easier to plan individual development paths and helps to close skills gaps in a targeted manner - efficiently and transparently.
What makes NotebookLM special?
NotebookLM works with the information you upload yourself - without any internet connection. This means that your data stays where it belongs. Every response can be transparently traced back to the original source. This means no "hallucinations" caused by external content, but reliable results based on your own documents.
Unlike many other AI tools - such as ChatGPT with file upload - NotebookLM is built from the ground up to analyze and link complex content and create usable texts from it.
Data protection is our top priority: Your data is not used to train AI models and is not viewed by humans within Google Workspace - even in business, enterprise or education accounts. This is a decisive advantage for companies with sensitive information.
Another highlight is the audio output: NotebookLM can output results in podcast style as an audible summary. In the so-called "discussion mode", questions can even be asked about individual audio content. This makes working with extensive documents not only efficient, but also more flexible.
How does NotebookLM:
With NotebookLM you can upload documents, whether they are presentations, documents, PDFs, texts, audio recordings or YouTube videos. You can ask NotebookLM questions about the uploaded information and it will provide accurate answers with sources. It can also create summaries of audio content, short reports or drafts of new texts.
