0:00 NotebookLM is now Gemini Notebook

If you're searching for NotebookLM's free versus paid plans, the first thing to know is that the name has changed. Back in July, Google renamed NotebookLM to Gemini Notebook. Google says it's the same standalone product, so if you see Gemini Notebook in your account, that's the one we're talking about. And the second thing to know: for individuals, there's no separate Gemini Notebook subscription.

You unlock more of it through a Google AI plan. So the real question is, does the free version cover what you do, and if not, which plan gives you enough? Let's go through Google's own help pages.

0:33 Source limits: free vs Plus, Pro, Ultra

Let's start with the hard caps, because these are actual numbers. Google's plans page for Gemini Notebook lists the limits by plan. Without an AI plan, you get up to a hundred notebooks, with up to fifty sources in each notebook. That counts every source type except notes, which have their own, much higher cap.

With Google AI Plus, that goes to two hundred notebooks and a hundred sources per notebook. With Google AI Pro, it's five hundred notebooks and three hundred sources per notebook. And Google AI Ultra comes in two versions in that table. Both get five hundred notebooks.

One allows five hundred sources per notebook, and the other allows six hundred. So here's the first test. Count your sources. If a project needs more than fifty documents, links, or files in a single notebook, that's the free plan's hard wall.

And Google says sharing a notebook doesn't change the source limit for anyone, so you can't get around it by having a collaborator add more.

1:23 Usage limits: 5-hour refresh and weekly cap

Now the second kind of limit, and this one's fuzzier. Google says Gemini Notebook has compute-based usage limits. They factor in how complex your prompt is, which models and features you use, and how long your chat is. Your quota refreshes every five hours, until you reach a weekly limit.

So it's not a flat number of chats or audio overviews a day. Heavy features use more.

1:45 Plan multiples and Generate later

Google publishes multiples instead of counts. Without a plan, you get standard limits. AI Plus is two times higher. AI Pro is four times higher.

And AI Ultra is five times or twenty times higher than AI Pro, depending on which Ultra subscription you have. The marketing page puts it in plain terms too. On Plus, more Audio Overviews and notebooks. On Pro, five times more Audio Overviews, notebooks, and more.

On Ultra, the highest limits. When you run out, Google says you can wait for the refresh, or upgrade. There's also a Generate later option. You can queue up something from the Studio panel, and it'll run later, which Google says may take a couple of hours.

That's on the web only. Your usage, and your weekly limit, show up in Settings, under Usage.

2:30 Sharing, watermarks and data

A few other differences that aren't about volume. Advanced sharing is only for paid users. Custom chat and analytics are available to everyone. Watermarks.

Google says images and videos made in Gemini Notebook with its image and video models carry an invisible SynthID watermark, and a visible watermark is added too. Google says eligible Pro and Ultra subscribers can control that visible watermark with a toggle. That's useful if you're making visuals for a video or a client. But in India, South Korea, and Vietnam, Google says the visible watermark is applied automatically.

Data. Google says your data isn't used to train Gemini Notebook unless you give feedback. And if you do give feedback, it may review the full context of that interaction. That's the same across these plans.

And one nice detail. Google says some people will see things like a report or an audio overview created automatically when they first add sources. Google says those are generated once and don't count toward your limits.

3:25 Google AI Plus, Pro and Ultra prices (US)

Now prices, so you can weigh it up. On Google's subscriptions page today, in the US, Google AI Plus is four ninety-nine a month. Pro is nineteen ninety-nine a month. Ultra starts at ninety-nine ninety-nine a month, and there's a higher Ultra tier at a hundred ninety-nine ninety-nine.

Those plans include a lot more than Gemini Notebook, like storage and Gemini app access, but here we're only looking at what they unlock in Notebook. Availability and prices vary by country. Google says Plus is in more than a hundred sixty countries and territories, and these plans are for people eighteen and over.

3:56 NotebookLM free or paid: which plan to pick

So how do you pick? If your notebooks have fewer than fifty sources and you only hit the usage limit now and then, stay free. The five-hour refresh and Generate later may be all you need. If you're a creator researching videos or a business owner organizing documents, and you keep hitting the fifty-source cap or running out mid-session, Plus is the cheapest step.

Double the sources, double the usage, for four ninety-nine in the US. If you live in Gemini Notebook, with big research projects, three hundred sources in one notebook, and lots of audio or video overviews, that's Pro territory. Four times the standard usage, and the visible watermark toggle. And Ultra only makes sense if you genuinely need the five hundred to six hundred source notebooks, or more usage than Pro, for serious, daily, heavy work.

Check how many sources your biggest notebook has, and how often you hit the limit this week. That tells you the plan. And if you want to know when Google changes these limits again, subscribe.
