NotebookLM Pricing: Free, $4.99 or $19.99, and What You Get

Contents

NotebookLM pricing at a glance

G

How much does NotebookLM cost? Nothing to start. Google renamed it Gemini Notebook in July 2026, and it is free with a Google account. To get more of it, you buy a Google AI plan: on Google’s US plans page on 15 October 2026, Google AI Plus was $4.99 a month, Google AI Pro $19.99 and Google AI Ultra $99.99 or $199.99. There is no NotebookLM-only subscription.

What you buy	Monthly cost, US	Room in Gemini Notebook	How much more use than free
Nothing (a Google account)	$0	100 notebooks, 50 sources each	Baseline
Google AI Plus	$4.99	200 notebooks, 100 sources each	2x
Google AI Pro	$19.99	500 notebooks, 300 sources each	4x
Google AI Ultra, smaller tier	$99.99	500 notebooks, 500 or 600 sources each	5x Pro’s
Google AI Ultra, larger tier	$199.99	500 notebooks, 500 or 600 sources each	20x Pro’s

I tested the free tier only, on 14 October 2026. I did not test any paid plan, a Workspace or Gemini Enterprise account, the student offer or the mobile app; every paid-plan figure here is Google’s, or my arithmetic on Google’s multipliers and my free-tier measurements.

Most people should start free. In my hands-on test on a Google account with no AI plan, five questions about four articles barely moved the meter. Audio and video overviews are what run it down.

You pay for a Google AI plan, not for NotebookLM

Google does not price Gemini Notebook on its own. Its plans help page opens: “You can upgrade Gemini Notebook to get additional capabilities, including higher limits and more features through Google AI Plans, Google Cloud, or a qualifying Google Workspace plan.” So there are three ways to pay: a personal Google AI plan, a work or school Workspace edition, or Gemini Enterprise through Google Cloud.

What you are paying for is mostly room. My free account was offered every Studio format, from audio overviews to slide decks. Paid tiers raise the notebook and source caps, add advanced sharing, and give you more usage before you hit a wall.

On personal accounts, usage is no longer counted in chats or overviews. Google’s usage-limits help page calls its limits “compute-based”: a long chat, a heavy feature or a complex prompt all cost more. You get a fresh allowance every five hours, capped by a weekly limit.

Google told users about this inside the app. On 14 October 2026 my account showed a pop-up promising “more flexibility and control”, which said limits now refresh every five hours instead of every 24, with one flexible Gemini Notebook limit in place of a limit for each feature. So a per-day count no longer describes a personal account.

Free, Plus, Pro and Ultra in detail

Here is what each personal tier gets, from Google’s plans help page and its US plans page, both read on 15 October 2026.

	Free	Plus	Pro	Ultra
Price a month	$0	$4.99	$19.99	$99.99 or $199.99
Notebooks	100	200	500	500
Sources per notebook	50	100	300	500 or 600
Advanced sharing	No	Yes	Yes	Yes
Earlier access to features	Standard	Early	Priority	Priority
Visible watermark removal	No	No	Yes, with exceptions	Yes, with exceptions
Cloud storage across Google	15 GB	400 GB	5 TB	From 20 TB

Free

The free tier, which Google’s help page calls Standard, is a full product. The US plans page lists it at “$0/ month with a Google Account” and describes Gemini Notebook in it as a “Research and writing assistant”. You get 100 notebooks and 50 sources in each, and the plans help page lists “Access to Gemini models”. On my free account, all nine Studio formats were offered.

Custom chat and analytics are free too. Google’s help page says “Advanced sharing available to paid users. Custom chat and analytics are available to everyone.”

Google AI Plus, $4.99

Plus is the cheapest upgrade. The plans page sums it up as “Get 2x higher usage access than Free”, and lists Gemini Notebook as “Research and writing assistant with more Audio Overviews, notebooks, and more.” The help page doubles the notebook cap to 200 and the source cap to 100.

Plus also brings 400 GB of Google storage and the other Google AI benefits on the plans page. Google says it is available in more than 160 countries and territories.

Google AI Pro, $19.99

Pro is the plan behind the “Gemini Notebook in Pro” column of Google’s plans help page, so it is the nearest thing to a NotebookLM Pro, and it is where Gemini Notebook gets roomy: 500 notebooks, 300 sources per notebook, four times the standard limits, “Higher access to Gemini models” and “Priority” access to new features. The plans page lists Gemini Notebook in Pro as “Research and writing assistant with 5x more Audio Overviews, notebooks, and more.”

Note the two figures. The same page says Pro gets “4x higher usage access than Free”, and the usage-limits help page says “Four times higher than standard limits”. I would plan on four times, the figure Google gives for limits, and treat “5x more Audio Overviews” as marketing for the card.

Pro’s wider bundle is large: 5 TB of storage, YouTube Premium Lite, Google Home Premium Standard and 1,000 Google Flow credits. On Pro and Ultra, Google’s plans help page also marks watermark removal as available, with an exception for a few countries.

Google AI Ultra, $99.99 or $199.99

Ultra comes in two sizes. The plans page reads “$99.99/ month: 5x higher usage limits vs. AI Pro” and “$199.99 / month: 20x higher usage limits vs. AI Pro”. Google’s plans help page has two Ultra columns, a 20 TB plan and a 30 TB plan, with 500 and 600 sources per notebook. The plans page says Ultra storage starts at 20 TB, so I take the $99.99 plan to be the 20 TB one.

For Gemini Notebook alone, Ultra is hard to justify. Its notebook cap is the same 500 as Pro. What it adds is much more usage, 500 or 600 sources per notebook against Pro’s 300, and “Highest access to Gemini models”.

Multiplied out, Ultra at $99.99 is five times Pro’s four, or 20 times the standard limits. The $199.99 plan is 20 times Pro’s four, or 80 times the standard limits. That is my arithmetic on Google’s multipliers, not a figure Google publishes.

How much one free five-hour window buys

Is NotebookLM free? Yes, but Google gives no count for the free tier, so the only way to size it is to spend it. I did that on 14 October 2026, on a Google account with no AI plan, for our Gemini Notebook review. The account’s own Usage dialog offered “Upgrade to AI Plus: Get double the usage than your current plan”, which puts it below AI Plus, on the free tier.

Five questions about four of our articles moved the five-hour meter to just 4.7%. Then the Studio dialogs showed what each output would cost before I clicked. Eight of the nine showed an “AI Usage” bar shaded for “Already used” and “Estimated use”; the percentages below are the widths the page itself set for those shadings.

Output	Expected cost on the free tier, as a share of one 5-hour allowance
Audio Overview	45%
Video Overview	35%
Infographic	11%
Data Table	6%
Reports	5%
Quiz	3%
Flashcards	2%
Mind Map	2%

By the end of the session I had asked five questions and made four Studio outputs: an audio overview, a mind map, an infographic and a data table. The Usage screen in Settings then showed 32% gone from the current window and 2% from the week. Its reset times were five hours and seven days after my first request.

One oddity: the meter rose to about 60% while those outputs were generating, then read about 30% once the audio overview had finished. Nothing on screen explained the drop, so treat the estimates as an upper bound rather than a final charge.

How to check your NotebookLM limits

Because the limits are a moving percentage, it is worth knowing where Gemini Notebook shows them. Google’s pages describe four places. I saw two of them on my free account.

Where	What it shows	Source
Settings, then Usage	Five-hour window and weekly limit, as percentages with reset times	My free account; Google’s usage page
In chat	A warning near the limit, and the time it resets	Google’s usage page
Each Studio dialog	Estimated cost of that output on a bar	My free account; Google’s usage page
Next to your profile image	A badge if you are on an upgraded plan	Google’s plans help page and work or school help page

The Usage dialog. Google’s usage-limits page says to open Gemini Notebook and, “At the top right, select Settings Usage.” On my free account, that dialog was headed “Gemini Notebook AI Usage & Limits” and said “This only represents your use of Gemini Notebook, not other products.” It showed two limits, the current five-hour window and the weekly limit, each as a percentage with a reset time.

The chat box. Google’s page says chat messages warn you as you get close, and quotes two examples: “You’re almost at your AI usage limit. Limit resets at 3:00 PM.” and “Limit reached. All features are available after 3:00 PM.” I did not reach either in my test.

The Studio dialogs. Before you generate anything, the dialog for that output shows its expected cost. Only the slide deck, which I opened late in the session, skipped the bar. Google’s page describes the same bar: “The more the bar is filled in, the higher the expected cost.” Checking it before you generate is the easiest way to stop one audio overview from using half your window.

The badge. To confirm an upgrade went through, Google’s plans help page says to “check to see if you have a distinct badge next to your user profile image”. The work and school help page names the badges: “Pro, Plus, Expanded, or Ultra”.

If you do want to upgrade from inside the app, Google’s usage page says to select Upgrade “In chat or studio generation”. The Settings menu on my account also had a highlighted “Upgrade Gemini Notebook” item.

Work and school accounts get a different table

If you sign in with a work or school account, the rules change. Google’s help page for work and school accounts says “Gemini Notebook is now a core service (like Gmail, Google Calendar, and Docs)” for Workspace and Workspace for Education users, and that higher limits need “a Google Workspace plan that includes higher limits.”

Unlike the personal pages, this one still publishes daily counts. They are set by the Workspace edition your organization pays for, not by a Google AI plan.

Per user, “Subject to Change”	Standard	More	Higher level	Expanded level	Highest level
Notebooks	100	200	500	500	500
Sources per notebook	50	100	300	400	600
Chats	50 a day	200 a day	500 a day	1,000 a day	5,000 a day
Audio Overviews	3 a day	6 a day	20 a day	40 a day	200 a day
Reports, flashcards, quizzes, mind maps	10 a day each	20 a day	100 a day	200 a day	1,000 a day
Deep Research	10 a month	3 a day	20 a day	30 a day	200 a day

Which column you land in depends on the edition. The page puts Business Starter, Enterprise Essentials, the Frontline editions, Nonprofits, and Education Fundamentals and Standard at standard access. Education Plus and the Teaching and Learning add-on get more. Business Standard and Plus, Enterprise Standard and Plus, and Google AI Pro for Education get the higher level. Two add-ons, AI Expanded Access and AI Ultra Access, sit at the top two levels.

The work page also makes a stronger privacy promise: “Your uploaded files, chats and model outputs won’t be reviewed by human reviewers or used to improve generative AI models.” On a personal account, Google’s plans help page says your data “is not used to train Gemini Notebook unless you provide feedback”, and that feedback may be reviewed in full context.

Paying for a team: Gemini Enterprise

Businesses can also buy Gemini Enterprise, which Google’s plans page lists under its Business tab. The Business edition starts at “$21 USD per seat per month” with a trial, up to 300 seats, and includes “Gemini Notebook for enterprise”. The Standard and Plus editions start at “$30 USD per seat per month” through sales, with “Higher usage limits for Gemini” and “enterprise compliance features in Gemini Notebook for enterprise”.

On the plans help page, the Google Cloud route promises “5X or more notebook artifacts, including Audio Overviews, Video Overviews, Reports, and more”, and says uploaded files “will remain within your GCP project.” I did not test any business plan.

Free for a year: the student offer

US college students may not need to pay at all. Google’s student page offers a “Free student plan for 1 year”, which its FAQ describes as “The free Google AI Pro student offer”, open to “eligible U.S. college students ages 18+”.

Read the fine print before you claim it. The page says “Valid form of payment required at sign-up” and “Unless cancelled earlier, Google AI Pro will automatically charge $19.99/month after the trial ends.” It also says eligibility “must be verified each year to maintain access”, and the offer can be redeemed “until December 31, 2026”. The student page itself lists Gemini app benefits rather than Gemini Notebook by name, but the plan is Google AI Pro, and Google’s plans page includes Gemini Notebook in Pro.

What each plan buys in practice

Google’s multipliers are abstract, so here is how they map onto the costs I measured. The arithmetic below divides my free-tier estimates by Google’s multipliers; it assumes the multiplier applies evenly, which Google does not promise.

A student turning lecture notes into audio. On the free tier, an audio overview was estimated at 45% of a five-hour window, so two in a sitting would use 90% of it. On Pro, at four times the usage, the same overview would be about 11% of a window. If audio is your main use, Pro, or the free student offer, is the plan to look at.

A researcher who mostly asks questions. Five questions used 4.7% of a free window in my test, roughly 1% each. At that rate, a long session of questions fits in one free window. The cap you are more likely to hit is 50 sources per notebook, and Plus doubles that to 100 for $4.99.

A team sharing notebooks. Advanced sharing is paid, and Google’s help page says “Sharing a notebook does not change the source limit for any collaborator.” If the team already has Google Workspace, check its edition before anyone buys a personal plan. Business Standard already sits at the higher level, with 500 chats a day.

Catches in Google’s pricing

Daily counts no longer apply to personal accounts

Of the Google pages I read, only the work and school page still gives daily counts, such as three audio overviews a day at the standard level, and they apply to Workspace editions. The personal-account page describes compute-based limits that refresh every five hours, with no counts. Check which account you are signed in with before you trust a number.

The meter is a percentage, and the paid tiers are multiples of it

There is no number of questions or overviews you can budget against. Google’s usage page warns that “we may at times have to cap the number of prompts and conversations you can have”, and that limits “may change.” Paying for Pro buys four times an amount Google does not publish.

Some outputs wait when you run low

Google’s usage page describes a “Generate later” queue for when you run out, which “may take a couple hours”. I met it with about 60% of a window used: the Slide Deck dialog had a single button, Generate later, and no Generate now.

The plans page shows monthly prices only

Google’s US plans page lists every AI plan by the month. It gives no yearly price, and its footer adds “No refunds for partial billing periods, except as required by applicable law.” It also says the plans are “only available for ages 18+”.

Ultra’s two tiers have different source caps

The $99.99 and $199.99 Ultra plans share a name but not a source cap. Google’s help page lists a 20 TB and a 30 TB Ultra plan with 500 and 600 sources; by the storage figures, I take those to be the $99.99 and $199.99 plans. If source count is why you are upgrading, Pro’s 300 may already be enough.

Matching a plan to how you use it

• Trying it out, or asking questions of a few documents: stay on Free. Chat barely moved the meter in my test.
• Running into the 50-source cap: Google AI Plus at $4.99 doubles the notebook, source and usage limits.
• Making audio or video overviews most days: Google AI Pro at $19.99, for four times the usage and 300 sources per notebook.
• A US college student: claim the free year of Google AI Pro, and set a reminder to cancel before it renews at $19.99 if you do not want it.
• At work: ask your Workspace admin what your edition includes before paying for anything yourself.
• Skip Ultra unless you also want its other Google AI benefits. For Gemini Notebook alone, it adds usage and sources but no more notebooks than Pro.

Other options

If your notes already live in Notion, Notion AI is our runner-up for AI notes. It builds pages, databases and decks from your workspace, but full AI needs Notion’s Business plan at $20 per member a month billed yearly, per our review. For a general assistant rather than a source notebook, our Google Gemini review covers what the same Google AI plans buy in the Gemini app.

Final word

Gemini Notebook is free, and for chatting with your sources the free tier goes a long way. Pay only when the meter, not the feature list, stops you: Plus at $4.99 if you need more sources, Pro at $19.99 if you make audio and video overviews often. Check the student offer and your Workspace edition first, because either may already cover it.
