Features and Capabilities

Will updates to the Google Doc or Slides be reflected in NotebookLM?

When you import a Google Doc or Slides into NotebookLM, we make a copy of the original Google Doc in NotebookLM at the moment of upload. Past this point, the app doesn’t keep track of changes to the file automatically, including access to it. NotebookLM can’t delete or edit your original files. You have to manually re-upload any local file, or use the Click to Sync with Drive button to refresh imported Google Docs and Slides in the source viewer.

What is the maximum file size limit for sources in NotebookLM?

The current limit is 500,000 words per source or up to 200MB for local uploads. There is no page limit.

What languages does NotebookLM support?

NotebookLM currently supports over 30+ languages. You can change your language preference in your Google Account settings.

Does NotebookLM support PDFs?

Yes, NotebookLM supports PDFs. However, there are some limitations:

PDF upload via Drive is not yet supported. Please upload PDFs from your computer.
Starting September 2024, image-only PDFs will be supported. While NotebookLM is improving its handling of images in PDFs, you may need to re-upload previously imported PDFs as functionality improves.

Do you have any tips on how I should get NotebookLM to summarize a source?

NotebookLM offers two modes for summarizing sources: you may ask for a summary of specific topics from your source directly in the chat, or you can find an auto-generated summary of the entire source in the Source Guide by clicking to open a source in the left hand side source viewer. When you ask for summaries in the chat for more specific summaries, try these tips:

Ask specific questions about the information you're looking for. If you have multiple sources selected, try including source names in your query to help NotebookLM narrow down the search. For example, instead of "Summarize this source," try "Summarize key findings about dog training from the source document titled Dog Training 101."

Can I work on a note collaboratively with others in real-time?

Yes! Note edits are reflected in real-time for all collaborators. If you have the same notebook open, any changes made by one person will appear for everyone else who has the notebook open. Only users being added as an “editor” to a shared Notebook can edit notes.

Why does NotebookLM sometimes say it can’t answer my question?

There are a few reasons why NotebookLM might not be able to answer your question:

Safety Flags: The content of your source might contain language that triggers a safety flag. This can occur with sensitive topics like violence, sexuality, or obscenity, even in historical contexts.
Unclear Phrasing: Try rephrasing your question to be clearer or more specific. When your notebook contains a large set of sources (that exceeds the LLM’s context window size), NotebookLM needs to first retrieve the most relevant information based on your question then try to build a response using this information. A more specific question will help NotebookLM locate these relevant bits of information.
Information Not in Sources: NotebookLM is designed to answer questions based on the information provided in your uploaded sources. If the answer isn't in the source material, it won't be able to provide a response.

When I import a source via URL, how does NotebookLM handle HTML sources with interactive elements?

Only the visible text on the page is imported. Improvements to this import type are underway.

How are sources, chat context, and notes used in responding to prompts?

Notes: Only used when specifically selected
Sources: Always used, either the entire set or the subset you've selected.
Conversation History: Also utilized in generating responses.

Is there a dark theme?

Yes, you can switch between light/dark/auto mode using the sun icon in the top right corner.

Troubleshooting

My source import failed, why?

If the source length exceeds the allowed word limit (500,000 words per source) or over the file size allowed (200MB), or if your original PDF file is copy-protected, NotebookLM won't be able to import those sources.

Why can't I access NotebookLM on my company or edu email address?

NotebookLM is currently available to personal Google accounts and participating enterprise Google Workspace or Google Workspace for Education users.

If you are using a company or edu email address and unable to access the app, please review this help center article and work with your workspace Admin to enable the NotebookLM app for your organization.

Why does my document look different in NotebookLM?

When you upload a document, NotebookLM may reformat the content in order to to parse the content.

Why don’t I always get citations?

If your source content is too short, NotebookLM will reference the entire document without citing individual text from your source.
