NotebookLM is the familiar name for Google's source-focused notebook tool. The official help pages reviewed for this entry now use Gemini Notebook. This entry keeps both names to help readers find the same workflow: collect sources for a project, ask questions about them, and create study or briefing material based on that collection. This guide explains its purpose and a starting workflow. [1]
Main features
The NotebookLM / Gemini Notebook guide describes a notebook as a collection of sources for a project. The Chat panel supports questions about those sources; the Studio panel provides outputs such as notes, reports, mind maps, and audio or video overviews. Notebooks are independent, and available features differ by surface. The source collection determines what your question can be answered from. [1]
Who should consider it?
Google's notebook workflow for questions, summaries, and outputs based on selected sources. Choose it for the task described here, then compare the requirements of your own project with its documented capabilities.
Getting started
- Open the product linked from Google's current notebook help page and sign in.
- Create a notebook and add a small, relevant set of sources you can review.
- Ask a focused question, naming the source when useful. Example: 'What deadlines does this project brief specify?'
- Inspect the cited source passages before using the answer. Create a report or overview only after checking the underlying material.

Free access and pricing
Google lists Standard access free of charge for eligible accounts, with higher notebook access through Google AI Plus, Pro, Ultra, and qualifying Workspace or education licenses. Source and output limits differ by tier. Check the current official table rather than applying Gemini app limits to the notebook product. [2]
Limitations and practical advice
eWiki's practical advice: incomplete sources lead to incomplete answers. Add the actual documents needed for the question, check import results, and distinguish the document's claims from the notebook's explanation. A polished overview is a generated interpretation, not a replacement for reading the relevant passage.
