Complete guide to NotebookLM
Getting started
Go to notebooklm.google.com with your Google account; the Standard plan is free and requires no card. Create a new notebook and upload your sources (PDFs, web links, Google Drive documents, audio, or video). NotebookLM analyzes the content and lets you chat with it, generate summaries, mind maps, data tables, or a conversational podcast-style audio summary, always citing the exact source passage that backs each claim.
Use cases
Studying and synthesizing academic notes
Upload all your notes and readings for a course to generate summaries, review questions, and concept maps grounded in your own materials.
Podcast-style audio summaries
Generates an audio conversation between two synthetic voices that summarizes and discusses your sources' content, ideal for reviewing while doing something else.
Autonomous research with Deep Research
Since November 2025, it lets you launch deeper research that automatically explores relationships between the uploaded sources.
Autonomous research agent (June 2026)
The June 2026 update turned NotebookLM into an agent that can execute code, search the web on its own, and export finished files, available only on the Ultra plan.
Advanced setup
- Organize sources by notebookCreate a separate notebook for each project or subject so context doesn't mix between different topics.
- Generate custom personasSince January 2026, you can define custom personas or tones for the assistant's responses within a notebook.
- Export to presentationsUse the slide review and PPTX export feature (added in February 2026) to turn the analyzed content into an editable presentation.
- Choose the right planIf you need more than 300 sources per notebook or frequent daily Deep Research reports, consider upgrading to Pro or Ultra based on your usage volume.
Tips
- Upload high-quality, well-organized sources: the noisier your documents, the less precise the generated summary will be.
- Use the podcast-style audio summary to review dense content during commutes or manual tasks, instead of rereading everything.
- Take advantage of the 1-million-token context window (added in October 2025) for notebooks with a huge number of sources without losing coherence.
- Before citing any data in serious work, verify the exact citation NotebookLM provides against the original document.
FAQ
Does NotebookLM make up information that isn't in my sources?
It's designed to answer only with what appears in the uploaded sources, citing the exact passage, which greatly reduces hallucinations compared to a generic chatbot.
What changed with the June 2026 update?
NotebookLM went from being a document-analysis assistant to an autonomous agent that can execute code and search the web on its own, though these advanced features are only available on the Ultra plan.
Is it really free, or is there a catch?
The Standard plan is permanently free, with daily usage limits; it requires no card and has no limited trial period.
Can I use it to write an academic paper directly?
It helps a lot with synthesizing and organizing ideas from your sources, but as with any AI, you should review and write the final version in your own words.
