Gemini Notebook’s usage limits change on 2 September. What that means for your business

On 28 August 2026, Google announced new Gemini Notebook usage limits, compute-based and flexible, rolling out from 2 September. In plain terms: a short question will now cost you less of your allowance than generating a video, you get topped up every five hours instead of once a day, and there is a weekly ceiling sitting above all of it.

Gemini Notebook is Google’s research tool, the one that used to be called NotebookLM. It answers only from the sources you upload, which is why small businesses use it for contracts, policies and meeting notes rather than asking a general chatbot. The catch has always been the ceiling: run out of chats at eleven in the morning on a free account and you were finished until the next day. That is the part being replaced.

What actually changed?

Google is replacing a fixed daily allowance with a compute-based one. Instead of counting how many times you did a thing, Gemini Notebook now counts how much work you asked it to do. Google’s own wording is that the limit will factor in the complexity of your prompt, the models and features you use, the length of your chat and specific features. A one-line question about a PDF is cheap. Generating a Video Overview from twenty sources is not.

Two other things move with it. Your allowance refreshes every five hours rather than once a day, so an afternoon is no longer written off by a busy morning. And when you do run out, you can queue an output instead of losing it: Google’s post says you can defer generating things like Video Overviews or Slide Decks, and they will generate automatically once your limit resets. In Google’s words, “This change will give you more choice over how you want to spend your limits and manage your tasks.”

What are the new Gemini Notebook usage limits?

Google has published no numbers at all for the new compute allowance. What it does publish is the per-feature caps that apply today, and the multiplier each paid plan gets. Those are the only figures anyone can quote you, and Google labels them subject to change.

Figures from Google’s own Gemini Notebook upgrade page, which marks them “Subject to Change”. Google AI Ultra sits above all three, and Google states its limits are 5x or 20x higher than Google AI Pro depending on the subscription.

Does this cost extra?

No. Google has announced no new charge and no new plan alongside this. The paid tiers work as multipliers of the free allowance: Google’s help page states that Google AI Plus is two times higher than standard limits, Google AI Pro is four times higher, and Google AI Ultra is 5x or 20x higher than Pro depending on which subscription you hold. If you already pay for one of those, your ceiling moves with it automatically.

What happens when you hit the limit?

You wait, or you queue the job. Gemini Notebook now shows your remaining usage at the bottom of the chat with the time it resets, in the form “Limit reached. All features are available after 3:00 PM”, and you can check the meter yourself under Settings, then Usage. When you are out, the “Generate later” button in the Studio panel holds a generation until your limit refreshes. Google notes that generating later can take a couple of hours and that this feature is currently only available on the web, not the mobile app.

Does this apply to a business Workspace account?

Not on the same date, going by what Google has published. The announcement says these updates are rolling out to consumer accounts on web and mobile starting on 2 September, and Google’s help page on usage limits makes no mention of Workspace at all. A qualifying Workspace or Workspace for Education licence is listed as a route into the higher tiers, so the plans connect, but the 2 September date is written for personal accounts. If your team runs on Workspace, expect this later and unannounced rather than on Wednesday.

What to ignore

Ignore the two loud readings of this, in both directions. It is not a stealth downgrade: Google has published no smaller number, because it has published no number. It is also not unlimited use. A refresh every five hours reads as a licence to work all day, and the weekly ceiling is the sentence that stops that being true. Ignore, too, the advice to upgrade pre-emptively. Nobody can size an allowance they have not used yet, and most small businesses will only meet the wall in September if they were already meeting it in August.

What should a small business do next?

Two steps, both free. First, before Wednesday, open Gemini Notebook, go to Settings and then Usage, and look at where you are now. That single screen is what turns “am I about to run out?” into something you can answer.

Second, put the work in the right order. Do the reading and the questions first, then generate the heavy outputs, because that is now the expensive end. This is also a good week to settle who uploads the sources and who asks the questions, which is the habit that makes any shared notebook worth having. It follows a busy month for Gemini generally, including interactive models and charts in the Gemini app, Ask Gemini inside Google Chat and the Gemini Live voice upgrade. If you would rather someone set the first notebook up with you and hand it over working, that is what an hour of Breezi Membership is for.
