The power tools you rely on — keep them running.

Yes! Every feature works without a license, except batch generation — several Studio types in one click, several items in one run, or the same preset on several notebooks — which is part of Pro. Pro users also get a clean, banner-free workspace plus early access to new features shipped weekly. Most Pro users say the focus alone is worth it.

A Pro license gives you batch generation (several Studio types in one click, several items in one run, or the same preset on up to 20 notebooks), a distraction-free workspace, early access to every new feature (shipped weekly), 5-device activation, and you directly fund continued development of the tool you rely on.

No. All three plans are one-time payments handled by Polar. Nothing renews and your card is never charged again. A 1-Month license works for 30 days, a 1-Year license for 12 months, and Lifetime never expires. There is no subscription to cancel.

Yes. All plans come with a 14-day refund policy. Email support@nlmtools.com within 14 days of purchase — no questions asked.

After purchasing through Polar, you'll receive a license key by email — check your Spam folder if it doesn't arrive. Open the NotebookLM Tools panel (click its icon in your browser toolbar, or open the side panel), click the "Unlicensed" button in the extension's own header, paste your key, and hit Activate. The "Unlicensed" tag on the NLMTools.com badge inside NotebookLM pages opens the pricing page instead — that's not the one.

Nothing is charged, and your data stays intact: tags, prompts, folders, and settings are untouched. The extension simply goes back to the free version (batch Studio generation needs Pro) and shows its reminders again: an "Unlicensed" tag on the NLMTools.com badge and, after using an on-page tool, a small upgrade reminder at most once a day. To continue, buy any plan again whenever you like. You'll get a new license key by email; paste it into the extension the same way you activated the first one.

Yes. Each purchase issues its own key; an old key is never extended. Open the NotebookLM Tools panel, click the "Unlicensed" button in the extension's own header, paste the new key, and hit Activate. It replaces the expired key and comes with its own 5 device activations.

Not at the moment. Lifetime is a separate purchase at the price shown above, and there is no automatic upgrade or credit for the time left on a 1-Year license. Your 1-Year key keeps working until it expires, and you can activate a Lifetime key in its place at any time.

Yes. All payments are processed by Polar.sh, a trusted payment platform. We never see or store your payment details.

Each license can be activated on up to 5 devices. You can deactivate devices or manage your activations anytime in the customer portal.

Both get all core features. Pro adds batch generation (several Studio types in one click, several items in one run, or the same preset on up to 20 notebooks), a clean workspace without prompts, early access to new features every week, 5-device activation, and the satisfaction of funding an indie tool's continued development.

Lifetime locks in today's price forever. 1-Month and 1-Year are one-time purchases at the price shown when you buy; if prices go up later, a future purchase would be at the new price. If you plan to keep using Pro, Lifetime is the way to lock it in.

The biggest Pro-exclusive feature is batch generation — several Studio types in one click, several items in one run (one per line), or the same preset on up to 20 notebooks, with live progress and a result for each item. Pro also removes all upgrade prompts and lets you hide the NLMTools.com badge on NotebookLM pages, gives you early access to new features every week, and supports up to 5 devices.
