Getting Started with NotebookLM
NotebookLM helps you when you have documents with answers. You know where the answers are. But the information is in different formats. You need the AI to stick to the facts in the documents. NotebookLM is perfect for this.
Understanding the NotebookLM Layout
When you open NotebookLM, you’ll see three main areas. Work from left to right. It’s a simple, three-column setup.
Sources Panel (Left): This is where you add all your files. You can add PDFs, slides, audio, and spreadsheets. You are telling NotebookLM that the answers are in these files.
Chat Panel (Middle): This is where you talk to NotebookLM. Ask questions here. Request summaries or pull out specific details. This is how you explore your sources.
Studio Panel (Right): This is where you create real things. You can make reports and slide decks. These are useful for your work.
First, load your sources on the left. Then, find answers in the middle. Finally, create usable items on the right.
Adding Sources to Your Notebook
You can add many types of files to NotebookLM. You can also find information from the web.
Using Discover Sources
Sometimes you need more information. Use the ‘Discover sources’ option. This lets you search the web.
In the Sources panel, look for ‘Discover sources’.
Choose ‘Web + Fast Research’. This works like a Google search. You stay within NotebookLM.
Type your question. For example, ‘top five AI models by usage in the Japan market’.
NotebookLM will show you a list of websites. Review these results.
Tip: Select a maximum of three sources. This helps you check each one carefully.
NotebookLM can even use sources in languages you don’t know. It can pull out the needed information and answer in English.
Searching Your Google Drive
You can also search your Google Drive files directly.
In ‘Discover sources’, choose ‘Drive + Fast Research’.
Type what you remember about the file. For example, ‘find that report with the AI model statistics on the Japan market’.
NotebookLM will find the file in your Drive. This saves you time searching manually.
Web + Deep Research
This option finds sources and summarizes them into a report. It’s good for getting a quick overview.
Use ‘Web + Deep Research’ to ask for a report on a topic, like ‘LLM model usage by country in Asia’.
NotebookLM reads the sources and creates a research report. You can add this report as a source.
Expert Note: For complex topics or when you have expertise, ‘Fast Research’ might be better. You can review sources yourself. Gemini, ChatGPT, and Claude may also offer better results for deep research.
Working with Live Documents
Pro Tip: If you add Google Docs, Slides, or Sheets, they are ‘living documents’. NotebookLM can get the latest changes from them. You can click to sync them. PDFs are static files. They do not update automatically.
Adding Text from Websites
If a website cannot be added directly, use this method.
Go to the website. Right-click and open ‘Reading mode’.
Highlight all the text. Copy the text.
In NotebookLM, paste the text under the ‘Copied text’ selection.
Interacting with Your Sources in the Chat Panel
The chat panel is where you ask questions and get answers from your documents.
Using Custom Instructions
For important tasks, add a custom instruction. This tells NotebookLM your main goal. Every answer will focus on this goal.
Find the ‘Configure chat’ window.
In the ‘Custom instruction’ box, explain your goal. For example: ‘Develop a business proposal for increasing Gemini’s monthly active users.’
NotebookLM will now answer questions based on this instruction.
Managing Your Conversations
After a few questions, you might want to start fresh.
Click ‘Delete chat history’. This clears the AI’s memory of past talks.
Before deleting, check for useful information. You can save important points as ‘Notes’.
Pro Tip: You can turn a saved note into a source. This makes sure it’s used in future work.
Using the Source Guide
Each source has a ‘Source guide’. This is very helpful for dense documents.
Click on any source in the Sources panel.
Look for the ‘Source guide’ at the top.
It shows key points from the source. This can give you ideas for follow-up questions.
Creating Deliverables in the Studio Panel
The Studio panel lets you turn your information into finished products.
1. Reports
Create briefing documents or analysis quickly.
Click on ‘Reports’ in the Studio panel.
NotebookLM suggests formats based on your sources. Choose one of these.
If no suggestion fits, you can ‘Create your own’. You can use a prompt template to guide it.
Enter the purpose and audience for the report.
Click ‘Generate’. NotebookLM will create a report based on your sources and instructions.
2. Slide Decks
Build presentations directly from your sources.
Click on ‘Slide decks’.
Choose ‘Presenter slides’ or ‘Detailed deck’.
Add a custom instruction. For example: ‘Create a deck to pitch my course to enterprise clients. Use action-oriented headlines and three talking points per slide.’
Click ‘Generate’. NotebookLM will create the slides.
Warning: When you download the slides, they might be images. They are not easy to edit directly. Use this tool to get a starting point for your presentation narrative.
You can also edit generated slides.
Click the ‘Revise’ button on a slide.
Give instructions for changes, like ‘Remove text and simplify the visual’ or ‘Use Google brand colors’.
Click ‘Generate new deck’ to apply changes.
Pro Tip: You can create vertical slides for social media. Add a custom prompt like ‘vertical slide deck in 9×16 portrait format optimized for mobile screens’. Download as PDF for posts.
3. Infographics
Turn your sources into a single visual for posts or sharing.
Click on ‘Infographic’.
Choose orientation (e.g., ‘1×1 square’).
Select a style (e.g., ‘Instructional visual’).
Choose the level of detail (e.g., ‘Concise’).
Add a prompt, like ‘Top five takeaways for Gemini Enterprise. Use Google brand colors.’
Click ‘Generate’.
Pro Tip: Upload your brand guidelines as a source. Reference them in your custom instructions for reports, slide decks, and infographics. NotebookLM will match your branding.
4. Mind Maps
See all your sources at a glance. This helps you decide what to focus on.
Click on ‘Mind map’.
NotebookLM creates a visual map of topics and subtopics from your sources.
Click on any topic to open a focused chat about that subject.
Tier 2 Tools (Situational Use)
These tools are useful for specific tasks.
Data Tables: Pull scattered data into a sortable table. Useful for comparing features or pricing. You can export to Google Sheets.
Video Overview: Turns your sources into a narrated slideshow. Good for long interviews or articles you don’t want to read. Cinematic mode creates animated sequences.
Quiz: Creates multiple-choice questions from your sources. Helpful for live events or study prep.
Flashcards: Helps memorize key terms or facts. Great for exam preparation.
Audio Overviews: Turns text into audio. Best for long newsletters you want to listen to on the go. Less useful for critiques or deep analysis.
Lightning Round: Common NotebookLM Notebooks
Here are some ways people use NotebookLM regularly:
Health Reports: Upload health reports to track changes and trends over time.
Meeting Notes: Store meeting transcripts to easily ask questions about past discussions.
Tax and Accounting: Upload financial statements and tax codes to understand deductions.
NotebookLM’s Strengths and Limitations
NotebookLM is highly accurate because it sticks to your sources. This is its biggest strength.
However, this also means it is less creative. For tasks that need creative thinking, like writing code or brainstorming ideas, use tools like Gemini, ChatGPT, or Claude. Google is integrating NotebookLM into Gemini, which combines accuracy with creativity.
