Gemini Notebook (Formerly NotebookLM) Pricing: Free, AI Pro and Workspace

Gemini Notebook (formerly NotebookLM) has five consumer tiers and several work routes. Standard allows 100 notebooks and 50 sources each, Plus 200 and 100, Pro 500 and 300, and Ultra 500 with 500 or 600. Most small businesses fit Pro or a Workspace edition that includes expanded access.

The tier names are the confusing part, because you rarely buy Gemini Notebook directly. You get a tier by holding a Google AI plan on a personal account, or by your administrator holding a qualifying Workspace edition on a work account. So the real question is which Google plan you need for everything else, and whether its Notebook allowance is enough.

The tiers side by side, from Google's plans page

Google publishes the limits on a plans page headed "Usage Limits (Subject to Change)", so treat every figure below as the position in early November 2026 and re-read the page before you pay. The notebook and source counts are the stable, countable limits. Chat and generation allowances are described in relative terms on the personal-account page, which is why they come later.

Two details save people money. First, sharing a notebook does not change the source limit for any collaborator, so a notebook you build on Pro does not shrink or grow for a colleague on the free tier. Second, a few items are generated automatically when sources are first added, such as a report, flashcards, an infographic, a slide deck, an audio overview or a video overview. Google says those are generated once and do not count towards your limits.

Chats, audio and reports: what the daily counts look like

The personal-account page tells you the chat quota is compute-based: Plus gets twice the standard access and Pro four times. It does not print daily numbers. Google's page for work or school accounts does, in a table of five access levels, and the first three columns match the notebook and source limits above (100 and 50, 200 and 100, 500 and 300). I would use that table as the best available guide to how the personal tiers feel in practice, while accepting that Google may rebalance the numbers.

Notice how lopsided the jump is. On a standard-access work account, a shop that asks a notebook thirty questions on a busy afternoon never touches the 50-chat daily cap, so the entry level is generous for question-and-answer work. The tiers bite on bulk generation: producing 15 reports in a day, or running more than ten Deep Research jobs in a month, is where standard access runs out. On a personal account the same pattern holds in relative terms, because a Deep Research job or an audio overview uses far more of the compute quota than a short question.

A worked sizing: a gift shop with 40 suppliers

Say a gift shop keeps one notebook per supplier relationship and one for each of its own policies. The owner wants to ask things like "which supplier has the longest lead time for ceramic items" and "what did we promise on returns of personalised goods".

• 40 supplier notebooks, each holding a price list, two or three email threads exported to PDF, the terms of trade and a delivery schedule. That is about 6 to 10 sources per notebook.
• 6 internal notebooks: returns policy, staff handbook, seasonal calendar, product care sheets, customer complaints log, packaging specs. Between 10 and 25 sources each.
• 2 notebooks for planning: one per season, holding last year's sales exports and supplier quotes.

The sum is 48 notebooks and no notebook above 25 sources. The free tier allows 100 notebooks and 50 sources, so the shop needs no paid plan for Notebook at all. If the owner later wants to merge all 40 suppliers into one searchable notebook, the count flips: one notebook of roughly 320 sources exceeds even Pro's 300, which would push towards the Ultra column. The better fix is to merge each supplier's price list, terms and delivery schedule into one document and keep one exported email thread per supplier, which leaves about 80 sources. That fits Plus.

Which plan suffices for a sole trader

A sole trader asks three questions. How many separate projects do I run, how big is the largest pile of documents, and do I generate lots of audio or slide output? A bookkeeper with 60 clients and a folder of about 20 documents each fits Standard on notebooks and sources. A consultant who builds one master notebook from 150 reports is already past Plus's 100-source limit, so that notebook needs Pro (300 sources); at 90 reports, Plus would do.

The cost logic is that the Notebook tier rides on a plan you may want anyway. Pro at $19.99 a month brings 5 TB of storage and Gemini in Gmail, Docs and other apps, per Google's subscriptions page, so Notebook becomes one reason among several. If Notebook is the only reason, count whether you ever hit 50 sources, or see the usage-limit message, on the free tier before paying. If you cannot remember hitting a limit, you do not need to upgrade.

For the sole-trader view of the personal plans without the Notebook angle, the tutorial on Google AI Plus or Pro for a one-person business covers the other allowances.

What a small team gets through Workspace

If three to fifty people share documents, the work-account route usually beats buying personal plans for everyone. Google's page for work and school accounts says Gemini Notebook is now a core service in Workspace, and that most users with a work account already have access. What changes by edition is the access level and the privacy terms.

• Business Starter and the Frontline and Enterprise Essentials editions get Notebook as a core service with standard access and enterprise-grade security and privacy.
• Business Standard and Business Plus sit in the "higher level access" column, which matches the 500 notebooks and 300 sources of Google AI Pro. Google's Workspace pricing page also lists Notebook with expanded access under Business Standard.
• Editions such as Business Base, Essentials Starter and Workspace Individual get Notebook as an additional service with standard access and no enterprise-grade privacy wording.
• Higher tiers, called Expanded and Highest access on that page, are add-ons: AI Expanded Access and AI Ultra Access.

Business Standard lists at about $14 a user a month on the annual plan (Google's pricing page, with an introductory discount for new customers on the first 20 users). Business Starter is about $7. For a six-person team that is roughly $84 a month on Standard against $120 a month for six Pro subscriptions, and the Standard seats come with 2 TB of pooled storage per user and admin controls. Confirm what your account shows at checkout, because Google changes promotions often. If you are weighing this very decision, Google AI Pro against Workspace Business Standard sets out the personal-versus-managed trade in full.

The enterprise route through Google Cloud

Google's plans page also describes Gemini Notebook for enterprise, reached through Google Cloud. Your cloud administrator grants access under Gemini Notebook for Enterprise, or under Gemini Enterprise Standard, Plus or Frontline. Google lists higher limits (five times or more notebook artefacts such as audio overviews, video overviews and reports), advanced sharing, and extra controls such as VPC Service Controls and IAM. Uploaded files stay within your Google Cloud project, and data regionalisation is honoured.

A business with fewer than around 50 staff rarely needs this. It matters if a compliance team demands that files never leave a specific cloud project, or if you already run other things on Google Cloud. Gemini Enterprise Business, shown on Google's subscriptions page from $21 per seat a month, is the small-team door into that family, but check how its Notebook allowance compares before assuming it beats Business Standard.

Privacy by plan: the difference that outweighs the limits

For many businesses the training and review terms matter more than the notebook count. Google's plans page splits them in two.

• Personal accounts (Standard, Plus, Pro, Ultra): data is protected and not used to train Gemini Notebook unless you provide feedback. If you do, Google may review the full interaction, including your queries, uploads and the model's responses.
• Workspace accounts: uploads, queries and responses are not reviewed by human reviewers, even when you give thumbs up or down, and are not used to train AI models.
• Google Cloud enterprise: files, chats and outputs are not reviewed by human reviewers or used to improve generative AI models, and files stay inside your project.

A practical rule follows. Client contracts, staff records and anything covered by a confidentiality clause belong in a work account, however small the business. A personal Pro subscription is fine for public material: your own published prices, product sheets and marketing notes. Many owners get this backwards, buying Pro for the larger limits and then loading client files into a personal account.

Three more sizing examples

A coworking space with a members' handbook

One notebook holds the house rules, the booking terms, the fire-safety notice, the printer guide and the visitor policy: 12 sources. The front-desk team asks it a few dozen questions a day between them. Each member of staff has a Business Starter work account, so standard access with Workspace privacy is enough, and nobody needs a personal plan. The only trigger for an upgrade is if the manager wants to generate a weekly audio briefing for every location, which would eat through three audio overviews a day.

A sports club preparing a sponsorship pitch

The club secretary uploads 90 sources: past sponsor reports, league tables, membership surveys, social post exports and press clippings. That sits under Plus's 100-source limit but over Standard's 50. She pays for one month of Google AI Plus while the pitch is prepared, then drops back to the free tier. Dropping back matters because her notebook may then exceed the free tier's source limit, so she exports the finished deck and the key answers first. Whether a notebook over the limit stays readable after a downgrade is not something Google's plans page spells out, so she does not rely on it.

An event venue answering enquiry emails

The manager builds a notebook with the price list, floor plans, catering menu, accessibility information and 20 past quotes, 30 sources in all. Drafting replies is the job, not bulk generation, so the daily counts never come close. The deciding factor is that quotes contain client names, which pushes the venue onto a Workspace account for privacy, not onto a higher paid tier.

A bookkeeper with an unruly shared folder

Before: one notebook called "Clients" holding 140 mixed sources, which hit the free limit at 50 and forced the owner to delete older files to add new ones. Answers also mixed up two clients with similar names. After: one notebook per client with 8 to 15 sources each, plus one notebook called "Procedures" for the engagement letter template, the month-end checklist and the document request list. The count becomes 61 notebooks and no notebook above 15 sources, which is inside the free tier. The change cost an afternoon, saved the monthly fee, and made every answer cite documents from one client only. Splitting by client is often the cheapest fix for a limit problem, and it is also the safer habit for confidentiality, because a question can never pull in another client's paperwork.

How to test whether you need to upgrade

Before paying, do a one-week limit log. It takes five minutes a day and replaces guesses with a count.

1. Open the notebook list and count how many notebooks you own. If you are over 80, you are near the free ceiling of 100.
2. Open your largest notebook and count its sources. Anything above 40 is close to the 50 limit.
3. Note each time a message says you have hit a limit, with the date and what you were doing.
4. Check for the distinct badge next to your profile image, which Google says shows you are on an upgraded plan.
5. At the end of the week, write down which single job hit a limit. If none did, stay free.

The classic overspend looks like this. An owner buys Pro because a forum post said the free tier was "limited", never hits 50 sources, and pays $240 a year for storage they did not need. The log would have caught it in a week. The opposite error is staying free while stuffing 200 PDFs into six notebooks, hitting the source limit, then splitting notebooks awkwardly so answers lose context. When the log shows a real limit, buy the smallest tier above it.

Which route to choose

My own default for a business with employees is Workspace first, because the privacy terms and the admin console matter more than any single limit. For a sole trader with no sensitive uploads, I would start free, log limits for a week and move to Plus only when a real one appears. To see what the notebooks are good for once you have chosen, read Gemini Notebook for small business teams, and if the plan question is really a wider one, Google Workspace against Microsoft 365 for AI is the next stop.

Limits that change, and how to stay current

Google labels the limits "subject to change", and its usage-limits help page now describes personal-account limits as compute-based quotas that refresh every five hours up to a weekly cap, rather than fixed daily chat counts. You can see where you stand under Settings, then Usage, inside Gemini Notebook. That is exactly the type of change that makes old tutorials wrong. Your habit should be to read two pages before any purchase: the Gemini Notebook plans page and Google's subscriptions page, both linked from Google's help centre. Daily quotas reset after 24 hours and monthly quotas after 30 days, per the plans page, so a limit hit on a Tuesday morning is not a reason to upgrade by itself.

If a vendor, a forum post or a video quotes a number that you cannot find on those pages, assume it is out of date. The same goes for any price: this tutorial quotes list prices in dollars, and your account may show a different currency or a promotion.

If you would rather map this with someone who has seen the trade-offs across several small businesses, that is what my AI implementation consultation covers; get in touch.

Plan questions owners ask before paying

Does a shared notebook use my collaborators' limits?

Google's plans page says sharing a notebook does not change the source limit for any collaborator, and that advanced sharing is for paid users. It does not spell out how each person's chats and generations are counted on a shared notebook, so assume each person's own plan sets their usage and test with one colleague before a whole team relies on it.

Is Gemini Notebook still called NotebookLM?

Google's help pages now call it Gemini Notebook, though many people still search for NotebookLM. The plan names, limits and the Workspace routes in this tutorial come from the renamed help pages. If you see old screenshots or prices quoted under the NotebookLM name, treat them as dated and check the plans page.

Can I buy Gemini Notebook on its own?

Not as a separate product. On a personal account the higher tiers come with Google AI Plus, Pro or Ultra, and on a work account they come with the Workspace edition your administrator buys. There is also an enterprise route through Google Cloud, which is aimed at larger organisations rather than a sole trader.

Will my uploaded documents train Google's models?

Google's plans page says data is not used to train Gemini Notebook unless you provide feedback, in which case reviewers may see the interaction. On Workspace accounts, uploads, queries and responses are not reviewed by human reviewers and are not used to improve AI models, even when you click thumbs up or down.
