Introduction

NotebookLM is a free AI tool from Google that helps you organize information, understand documents, and create useful content faster. It is powered by Google’s Gemini AI models and is designed to work only with the information you provide. This makes it more accurate and trustworthy than many general AI chat tools.

What Makes NotebookLM Different from Other AI Tools

NotebookLM is built around knowledge grounding. This means it only answers questions using the documents and sources you upload.

Instead of guessing or making up answers, NotebookLM cites information directly from your files. This greatly reduces incorrect or misleading responses and makes it suitable for research, study, and work tasks.

You can learn more about Google’s Gemini AI on Google’s official AI blog.

How to Add Sources in NotebookLM

NotebookLM allows you to upload many types of content as sources.

You can add:

• PDF files

• Text and markdown files

• MP3 audio files

• Google Drive documents

• Website links

• YouTube video transcripts

If an article is behind a paywall, you can simply copy and paste the text into NotebookLM and use it as a source.

If you do not have your own documents, NotebookLM also has a Discover Sources feature. It works like a Google search and suggests helpful resources based on your topic.

Saving Notes and Managing Information

NotebookLM does not automatically save chat responses.

If you want to keep an answer, you must click “Save to note.” Saved notes can later be converted into new sources. This helps you build a growing knowledge base over time.

Each notebook can hold up to 50 sources. Each source can contain up to 500,000 words. To save space, you can merge multiple documents into one source.

Practical Uses of NotebookLM in Daily Life

Quick Answers from Your Own Documents

You can upload manuals, reports, or project files and ask direct questions. NotebookLM will find the answer from your documents instead of searching the internet.

Business and Team Knowledge Base

Businesses can store training materials, SOPs, and product guides in one notebook. Team members can share access, making onboarding and customer support easier and more consistent.

Learning and Education Support

Students and teachers can use NotebookLM to create flashcards, quizzes, study guides, and mind maps. This helps improve understanding and memory without extra effort.

Journaling and Self-Reflection

You can upload written journal entries or audio notes. NotebookLM can turn them into summaries, mind maps, or audio overviews. This can help you see patterns in your thoughts and improve self-awareness.

Public Notebooks from Experts

On personal Google accounts, NotebookLM gives access to public notebooks created by expert curators.

These notebooks include ready-made podcasts, FAQs, and mind maps on popular topics. They are useful if you want high-quality information without creating everything from scratch.

Content Creation and Repurposing with NotebookLM

Audio Overviews and Podcasts

NotebookLM can create audio discussions using two AI hosts who talk about your uploaded content. You can also ask questions during the audio session. The audio files can be downloaded and shared on podcast platforms.

Video Overviews

Using Google’s Vids technology, NotebookLM can generate presentation-style videos. These videos come in different styles such as classic, whiteboard, watercolor, retro, heritage, and anime. Videos can be downloaded as MP4 files.

Turn One Idea into Many Formats

NotebookLM makes content repurposing easy. A YouTube video can become a blog post, a podcast, or social media content. Audio notes can become articles or videos. This saves time and increases productivity.

Pro Tips for Using NotebookLM Effectively

• Always save important responses to notes because there is no chat history

• Use different types of sources like PDFs, videos, audio, and blogs for better results

• Uncheck specific sources if you want the AI to ignore them for a question

• Add personal notes that stay private unless you convert them into sources
