Frequently Asked Questions

Is NotebookLM free?
Yes — NotebookLM has a free tier that lets you upload sources and generate summaries and Q&A. For heavier usage and expanded features, it's included with Google AI Plus ($7.99/mo), AI Pro ($19.99/mo), and AI Ultra ($249.99/mo) plans.
What types of sources can I upload to NotebookLM?
You can upload PDFs, Google Docs, Google Slides, web URLs, YouTube videos, and audio files. NotebookLM grounds all its answers in those specific sources — so you're not getting generic web results, you're getting insights from your actual material.
How is NotebookLM different from ChatGPT or Claude?
The big difference is source grounding. ChatGPT and Claude draw on their training data and the open web, while NotebookLM only references the documents you upload. That makes it much better for research workflows where you need answers tied to specific sources with citations you can verify.
