NotebookLM / Gemini Notebook: study your own sources

Build a useful source collection

Start with a few documents you understand: public instructions, your own non-sensitive notes, or material you have permission to use. Give sources descriptive names and note their dates. A notebook full of conflicting editions is harder to use reliably than a small, clear collection.

Google's help describes source-linked chat, notebooks, notes, and generated study formats. The current interface and limits should be checked in those instructions. Google: Gemini Notebook (NotebookLM) Help Center

Try a project question

Create a notebook about a fictional community workshop. Add the event plan, an equipment checklist, and a venue policy. Ask what is agreed, what is missing, and which source supports each answer. Open the citations before accepting the summary.

Using the selected sources, list the workshop's confirmed requirements and unresolved questions. Cite the document and supporting passage for each. If two sources disagree, show both statements and their dates. Do not resolve the conflict by guessing.

The most useful result may be a list of questions to ask the organizer. Save the checked answer with its citations rather than relying on a polished overview alone.

Work carefully with videos

Google's source-import instructions say that supported public YouTube imports use the video's transcript and require captions. The imported source therefore does not establish what appears only in a demonstration, chart, or silent sequence. Google: source-import requirements

For a playlist, choose a small set of relevant videos and confirm that each source imported successfully. Do not assume a playlist link means every item was ingested. A speaker's claim remains that speaker's claim, even when the notebook summarizes it fluently.

Turn summaries into learning

Use a generated overview to orient yourself, then ask questions that require evidence. Compare two authors' definitions, identify a disputed assertion, or create practice questions from a reliable source. Attempt the questions before revealing answers.

For audio or other generated overviews, keep access to the original written material. Review names, numbers, and qualifications before sharing. Check sharing permissions for both the notebook and its contents, especially when other people supplied documents. A source-based assistant makes verification more convenient; it does not remove the need to verify.
