If NotebookLM is responding based on an old policy, first open the source itself inside the notebook and find the changed paragraph. Then check which documents and notes are selected for the new question. That will help you separate a data update issue from an answer-generation error.
In the current Google help, the service is called Gemini Notebook; below we also use the familiar name NotebookLM. This FAQ is for support leaders, sales teams, and owners of internal procedures: it helps clarify document changes in the desktop web version. We do not cover service availability, pricing, or enterprise security settings here.

Key point: Connecting a Drive file, uploading a copy, and saving an answer as a note are different operations. Verify the document path in the notebook before uploading the entire set of materials again.
What data do you need for the analysis?
One specific discrepancy is enough: what the current document says and what the assistant answers. Prepare the notebook name, the original document, how the source was added, and the question that produced the old answer. For the first check, do not use real client data: take an approved training document.
For examples, let’s imagine a support department procedure. Previously, requests were routed to the “General Inquiries” queue, and now they go to “Equipment Service.” These names are illustrative. The goal is to determine whether the new wording reaches the answer, and then verify the quote.

Do Drive files update automatically?
Yes. For sources imported from Google Drive, the current help describes automatic updates every few minutes when the notebook is opened. If needed, you can open the source and choose “Click to sync with Google Drive.” This is the documented process, not a delivery time we measured ourselves. Help on importing sources.
Open the original, make sure the edit is saved, then open the notebook and the matching source. Find the new wording in its text. Just seeing the file in the list does not answer the question of which revision it contains.
Do not look for a separate auto-sync toggle: Google has said there is no user setting for this feature. Older instructions that require manual refresh of each Google Doc describe the previous behavior. Official statement on Drive sync.
What should you do with PDF files and web pages?
First, determine how the material was added. A PDF downloaded and uploaded from a computer, and a file imported through Drive, have different update paths. Google’s auto-sync rule applies to Drive imports; it does not confirm updates for every copy with the same name. Import types and methods.
For a local copy or a web page, we suggest this diagnostic approach: compare the visible text in the source with the original; if the revision is old, add the current version separately and temporarily select only that one. Before deleting the previous source, make sure the old material is not needed for comparison. This is an editorial recommendation, not a Google-stated automatic replacement process.
| How the material was added | What to find out first | What counts as a useful verification result |
|---|---|---|
| Imported from Drive | Whether it is the correct original and whether access is still available | The new paragraph is visible inside the source |
| Uploaded from a computer | Which revision was uploaded | The current copy is selected for the question |
| Website URL | Whether the needed rule appears in the text of that page | The rule is present in the imported text |
| Note from the answer | When and from which materials it was created | The old note is excluded from the diagnostic query |
A common mistake is renaming an old copy to “Current” and considering the task solved. The name helps with orientation, but the content is what needs to be checked.
Why didn’t the new paragraph make it into the source?
Check the location of the edit and the import boundaries. Google does not import comments or footnotes from Google files. When you add an HTML page, its text is loaded; nested pages, images, and embedded video are not included. Import limitations.
If an employee wrote a new processing queue in a comment on the procedure, that is not yet a new revision of the main text. Ask the document owner to move the approved rule into the appropriate section. If the rule is published on another page of the site, add that exact page, with the necessary permissions.
The sign of success at this stage is that the needed fragment is readable in the notebook source. Until it is there, rephrasing the question does not fix the missing data. Do not ask the model to “infer it from context”: for an operational policy, that creates a new unverified version of the rule.
Why is the source new but the answer old?
Check the selected sources and ask a new, narrow question. In the chat, you can manage the set of materials used for the answer and open citations in context. Chat usage help.
In the training example, clear the selection from the other documents and ask: “According to the selected procedure, which queue are equipment-related requests sent to? Provide the supporting excerpt.” Then open the citation. This is a suggested diagnostic prompt, and we did not verify its result in the service.
If the citation points to the current paragraph, but the answer wording contradicts it, the source has already been updated: at that point you need to analyze the generation error. If the link points to a different document, check the material selection. If you keep the old conversation going, remember that chat history also affects the answers. Official FAQ.
Do not mix this check with a conversation in the Gemini app. Google separately describes the differences: Gemini answers may include web search and other tools alongside notebook materials. To analyze a discrepancy, note which app produced the answer. Notebooks in Gemini Apps.
Can a saved note interfere?
Yes. A selected note can itself take part in the answer as a source. The current help allows you to save an answer with “Save to note”; notes appear among the sources, and the checkbox controls whether they are included in the context. How notes work.
For example, you previously saved a note with the “General Inquiries” queue. After correcting the original procedure, that note is still in the notebook as well. In that case, we suggest temporarily excluding it and repeating the same question using only the current document. If the answer changes, compare the citations: a single changed answer does not by itself prove the cause.
Do not use an old AI answer as proof of the current procedure. For a new reference note, first check the source document, then prepare the text and clearly state which version it is based on. A saved interpretation and an approved policy serve different purposes.
How do access and file deletion affect it?
After you lose access to the original Drive file or it is deleted, the source becomes unavailable for interaction and new responses; inactive sources still count toward the limit. This applies to both personal and shared notebooks. The help guide includes a link to request access or to remove an inactive source from the list. Access to Drive sources.
If a document no longer appears in responses, first open the original with the same work account. Ask the owner to restore the needed access or provide an approved current version. Re-uploading someone else’s copy does not replace permission approval.
Do not assume this means a note already sent to colleagues or an export will automatically disappear. Check every distributed item separately. Rights to the source document and the lifecycle of derivative texts are related, but separate tasks.
Why doesn’t editing an export change the notebook?
An export creates a separate document. Changes made in exported Docs and Sheets do not sync back to Gemini Notebook content; access rights for the export also do not transfer from the notebook. Creating a notebook and exporting materials.
If a manager revised a note in an exported Google Docs file, determine where the approved original is now located. If needed, add that document to the notebook as a source and remove the outdated version from the working set. Check access separately for export recipients.
This is an easy place to create a loop: an AI answer is exported, edited, imported, and then treated as the original policy. Mark the document’s origin. For an operational decision, it is better to have a clear link to the approved rule, not just a paraphrase.
How do you verify the result without taking it on faith?
Compare the new wording in the source, the new answer, and the quoted passage. Google lets you select a quote and jump to its context. A citation icon helps with verification, but it does not replace reading the evidence. Checking citations in chat.
For our example, use this criterion: the source contains "Equipment Service," the new answer to the routing question names that queue, and the quote confirms the routing rule itself. If the source is short, the service may cite the entire document — this is described in the official FAQ. In that case, find the rule manually. Citation specifics.
After that, ask a work question in a standard employee phrasing. Successfully verifying one fragment does not confirm that all answers in the database are correct. If you need a controlled enterprise system with its own document-handling rules, separately review a business RAG system. Moving to it requires separate design.
How AIrassvet helps work with policy versions
When the same issue keeps coming up across different departments, it helps to understand how the corporate knowledge base is structured. In work with data, RAG systems, and integrations, AIrassvet can help:
- identify approved policy sources and separate them from paraphrases;
- prepare documents and version information for corporate search;
- connect assistant answers with sources in employees’ workflows.
The first step is to choose one policy, show the current original, an example of an incorrect answer, and access restrictions. This makes it possible to discuss a specific issue without promising a particular result in NotebookLM. Discuss the issue.
What to do now
Open one source with a discrepancy and find the changed rule. If it is not there, examine the import method and access to the original. If the rule is already visible, check the selected documents, old notes, and the new citation. This sequence helps determine which exact material needs to be corrected before changing the entire knowledge base.
