Dive into the full core capabilities of Google’s AI note-taking tool NotebookLM—from source-grounded AI to the Gemini 3.5 upgrade, from document analysis to cloud code execution—to power your research and knowledge work.
Start Using NotebookLM for FreeNotebookLM’s core differentiator. AI output is strictly based on documents you upload—never invented from thin air. Every answer includes clickable citation links so you can jump directly to the original passage for verification, effectively addressing the hallucination problem in general-purpose AI.
Flexibly supports many document formats to help you build a complete knowledge base: PDF files, Google Docs and Google Slides, web URLs (automatic content capture), YouTube videos (automatic transcription), and pasted plain text. The free tier supports up to 50 sources per notebook.
On June 8, 2026, NotebookLM upgraded to the Gemini 3.5 model. It achieves an average win rate above 65% across five core evaluation dimensions, 69.9% on large document analysis, and 78.2% on advanced web research and source discovery—with more transparent reasoning and more accurate, reliable answers.
Each notebook includes a secure cloud computer for writing and running code such as Python. With 100+ built-in software skills, you can perform data cleaning, statistical analysis, chart generation, and other deep data processing—effectively embedding a lightweight data analysis environment inside your note-taking tool.
Export research results in multiple formats with one click: PDF and Word document reports, Excel spreadsheets, PowerPoint presentations, structured data in CSV and JSON, and data visualization charts in PNG and SVG—meeting delivery needs across different scenarios.
Turn lengthy documents into engaging two-host AI podcast-style conversations that vividly summarize key content. Interactive mode lets you ask questions while listening—ideal for auditory learners, commutes, and quickly grasping document highlights.
No need to prepare a complete library upfront. Start a research project from a vague idea or question in the chat, and NotebookLM uses Google Search to discover and recommend high-quality sources—automatically building your library and dramatically lowering the barrier to starting research.
Share notebooks with multiple people and set view or edit permissions. Team member updates sync in real time—ideal for research groups, project teams, and enterprise knowledge base collaboration, ensuring everyone performs AI-assisted analysis on the same source materials.
