How to use NotebookLM (now Gemini Notebook) to question your own contracts, handbooks and quotes, create audio summaries and keep your documents safe.

A business owner using NotebookLM (Gemini Notebook) to ask questions about PDF documents and listen to an audio summary

NotebookLM is Google's free AI tool for reading and answering questions about your own documents: contracts, staff handbooks, catalogues, quotes. In July 2026 Google renamed NotebookLM Gemini Notebook; it works the same way and lives at the same address. This guide uses both names, since many people still search for NotebookLM.

This NotebookLM guide is for non-technical small business owners: your first notebook in 5 minutes, 5 practical uses in a shop or small company, audio summaries (including in Vietnamese), the limits of the free plan, and privacy.

1. How NotebookLM differs from ChatGPT and Gemini

ChatGPT and Gemini answer from general knowledge. NotebookLM is different: it answers only from the documents you give it, and adds numbered citations you can click to see the exact passage.

Think of it as a new employee who reads very fast: you hand over a stack of documents, they read everything, then answer your questions about that stack and point to the page and line.

That makes NotebookLM a good fit for:

  • Finding one clause in a 30-page contract.
  • Answering staff questions from your handbook and policies.
  • Comparing quotes and catalogues from several suppliers.

It is not the right tool for creative marketing copy or questions your documents don't cover. Use ChatGPT or Gemini for those.

2. Your first notebook in 5 minutes

All you need is a Google (Gmail) account.

  1. On a computer, go to notebooklm.google (notebooklm.google.com also works). On a phone, install the app whose developer is Google LLC; depending on the version it is called NotebookLM or Gemini Notebook.
  2. Sign in and create a new notebook.
  3. Add sources: upload PDFs, pick files from Google Drive (Docs, Slides), paste a website or YouTube link, or paste text directly.
  4. Wait a few seconds while it reads. Then type questions in the chat box as you would in any messaging app.

Tip: keep one notebook per topic: one for "Shop lease", one for "Staff handbook", one for "Supplier quotes". Mixing unrelated documents makes answers less accurate.

3. Answers with citations: how to check them

Each answer has small numbers after its points. Hover over or tap a number and NotebookLM opens the exact passage in the original document.

Make a habit of checking at least one citation for anything important (money, deadlines, responsibilities). NotebookLM makes things up far less often than a general assistant, but it can still misread a long sentence or miss an exception.

You can also untick sources in the left-hand panel to ask about just one or two documents.

4. 5 ways to use NotebookLM in a small business

A staff assistant built on your handbook

Upload your house rules, opening checklist and returns policy. A new hire asks "A customer wants to return something after 10 days. What do I do?" and gets an answer with citations. You can share the notebook with staff by their Gmail address, just like a Google Doc.

Comparing supplier quotes

Upload three PDF quotes and ask:

Make a comparison table of these quotes: unit price, minimum order,
delivery time and payment terms. Point out any terms that are
unfavourable to the buyer.

Reading a contract before you sign

Upload a lease or distribution agreement and ask:

List all fees, penalties, termination conditions and the tenant's
obligations. Cite the exact clauses.

NotebookLM helps you know what to ask, but it is no substitute for a lawyer on a high-value contract.

Understanding rules from official texts

Instead of reading opinions online, download the official regulation or guidance from a government website, add it as a source and ask in everyday language. The answer sticks to the text and points to the clause.

Training staff with audio

Turn training documents into an audio summary your staff can listen to on the way to work (see the next section).

5. Audio, video and mind map summaries

Beyond Q&A, NotebookLM can turn your documents into several kinds of summaries:

  • Audio summaries: a conversation between two AI hosts discussing your documents. Many languages are supported, including Vietnamese. If yours comes out in the wrong language, change the output language in the settings and generate it again.
  • Video summaries: a narrated slide presentation, handy for introducing a process.
  • Mind maps: a diagram of the main ideas and how they connect.

You'll find these on the right-hand side of the screen (a separate tab on mobile). They take a few minutes to generate.

Note: audio summaries sound so natural that they are easy to trust. Check numbers, prices and dates against the original before using one for training.

6. How far does the free plan go?

According to Google's help pages at the time of writing, a free account gets:

  • 100 notebooks, each with up to 50 sources.
  • Up to about 500,000 words or 200 MB per source, roughly a thick book.
  • A daily limit on questions and on audio and video summaries; when you hit it, wait until the next day.

For a shop or small company, the free plan is usually enough. Google's paid AI plans raise these limits; consider them only if you keep running out.

7. Privacy when uploading documents

Your documents are stored on Google's servers. For personal Gmail accounts, Google says your NotebookLM content is not used to train its AI models unless you give feedback (thumbs up or down) on an answer, in which case the related content may be reviewed by people at Google. So:

  • Avoid rating answers in notebooks that contain internal documents.
  • Remove personal data before uploading: ID numbers, bank details, customer phone numbers, payroll.
  • Don't upload documents you are obliged to keep confidential for a partner unless they agree.
  • Review who a notebook is shared with whenever someone leaves the business.
  • Turn on 2-step verification for Gmail, since every notebook is tied to that account.

8. Where to start

  1. Today: create a notebook, upload one long document you need to read (a contract or policy), ask 3 questions and check the citations.
  2. This week: generate an audio summary in your language and listen on the way to work.
  3. At the weekend: put your shop's handbook and procedures into one notebook and share it with one employee to try.

Checked in October 2026. Google is gradually renaming NotebookLM to Gemini Notebook across its apps, so what you see may differ slightly from this guide.
