Gemini Notebook: documenting the NotebookLM infrastructure
Gemini Notebook is a processing system that operates strictly on user-supplied sources: it ingests files, links and video as input, and from that set generates summaries, audio overviews, video overviews, mind maps, reports, flashcards and a quiz. Until recently the product carried the name NotebookLM, and its free-plan capacity is a hundred notebooks with fifty sources per notebook.
- nine output formats
- fifty-source capacity on the free plan
- Persian output support

The rename, and its effect on documentation
The official product page, the browser tab title and Google support centre all carry the name Gemini Notebook. The address built on the NotebookLM name remains live and functional, but it is no longer the name under which the product is introduced. The practical consequence of this rebrand: any tutorial indexed under the old name may document a different interface, and searching the new name in Persian returns effectively no results.
Architectural distinction from a general-purpose chatbot
A general-purpose chatbot generates answers from the entire web. Gemini Notebook, by contrast, produces output exclusively from the closed source set the user supplies, and cites every sentence back to that source. For study use, this architectural difference is decisive: in a closed-source system, even an incorrect answer is traceable, and the originating document can be identified precisely.
The output layer is bound to that same source set. From one source set it generates nine formats: notes, audio overviews, video overviews, mind maps, reports, data tables, flashcards and a quiz, slide decks and infographics. The audio overview is typically the entry point for most users, but in terms of learning outcome, the component with actual effect is the quiz, not the audio overview.
Quantitative plan specifications
Free tier: a hundred notebooks, fifty sources per notebook, a ceiling of 500,000 words per source, fifty chat queries a day, and a daily cap of three audio overviews and three video overviews. Paid tiers raise those same parameters to 300, 500 and 600 sources per notebook. For a single academic term workload, the free tier rarely becomes the bottleneck; the first limit reached is the daily cap of three audio overviews.
Persian-language coverage
Persian is registered on this system output-language list, and per Google documentation, the selected language applies to the study guide, documentation, audio overview and chat-response layers. This means English-language input can produce Persian output. The output-language setting is independent of other configuration and defaults to the user Google Account language, so an English-language account must change this parameter manually.
Operational constraint for an Iranian user
Iran is not registered on the supported-region list for the Gemini apps, and the product documentation states that this system operates in the same regions where the Gemini app operates. This reference neither sells accounts nor proposes a circumvention method.

Using it from Iran
This column carries a date and says how it was checked, because most listicles guess it. Where we have only read a vendor policy page, the note below says exactly that.
- Reachable
- blocked
- Payment
- no working route
- Free tier
- yes
- Measured on
How we checked: Per Google official documentation, Gemini Notebook operation is confined to the same 180-plus regions where the Gemini app is active, and Iran does not appear on that app supported-region list. This finding comes from reading the source document, not from a network measurement; a direct probe from inside Iran has not yet been run.
Documented strengths
- Generates output exclusively from the user source set and cites every sentence to it, lowering the rate of unsupported claims
- Nine output formats from a single source set, from audio overviews to flashcards and a quiz
- Free-plan capacity is typically sufficient for one academic term: a hundred notebooks with fifty sources each
- Produces Persian output from English-language source material through one simple setting, with no workaround required
Known weaknesses and limits
- The free-plan ceiling is three audio overviews and three video overviews a day, and this constraint is the first operational bottleneck.
- Iran is not registered on the supported-countries list, and no official access route exists for an Iranian user.
- Because the system architecture relies strictly on the input source, an incomplete source produces an incomplete output, with no external data added.
- Output quality depends directly on the quality of the extracted text; a poor scan or handwritten notes degrade the result accuracy.
- The product name has changed, and the majority of existing tutorial material still documents the previous interface.
Technical verdict
If you hold a defined source set and the objective is to learn that material, this system is engineered precisely for that function and has no close competitor in this table. Operational recommendation: configure the output language first, run the quiz second, and go to the audio overview last. The reverse sequence is the pattern most users follow, and it yields the lowest learning return.
Frequently raised questions, with documented answers
Does Gemini Notebook have a free plan
Yes. Free-plan specification: a hundred notebooks, fifty sources per notebook, fifty chat queries and three audio overviews a day. Paid tiers raise these ceilings.
Is Persian supported
Yes. Persian is registered on the output-language list, and per Google documentation, the selected language applies to the study guide, audio overview and chat-response layers.
What is the source capacity per notebook
Fifty on the free plan, with a ceiling of 500,000 words or 200MB per source. Higher tiers raise this capacity to 300, 500 and 600 sources per notebook.
