NotebookLM use cases

At a glance

Tested in Gemini Notebook on October 30, 2026. Times will vary with your sources.

For study

Prepare for an exam

Add: lecture notes, slides and readings.

Try: "What are the five ideas most likely to come up, and where is each covered?" Then make Flashcards and a Quiz in Studio. Flashcards let you choose the number of cards and the difficulty, and tell them what to focus on. The Study Guide report adds a short-answer quiz, essay questions and a glossary.

Why testing yourself works: AI for studying, by the numbers.

Learn from YouTube lectures

Add: a lecture or a course, by link.

Try: "Explain the part on recursion as if I missed the class."

A course of almost 25 hours imported in under a minute. Videos in Hindi, Japanese and Spanish worked too, and we could ask about them in English. Don't ask for timestamps, though: the chat gave us one that was 23 minutes off. All 18 links we tested

Review on the go

Add: whatever you need to review.

Try: an Audio Overview. Deep Dive is a conversation between two hosts, Brief is a short summary, Critique is an expert review of your material, and Debate gives two sides. Ours ran 14 minutes 15 seconds and took about 6 minutes to make. KastorFlow can publish Audio Overviews to a podcast feed for any podcast app (Pro).

For research

Review papers and reports

Add: the papers, as PDFs or PDF links.

Try: a Data table with the columns you need. We asked for "task, datasets used, best reported result, year, and main idea" across two papers. It came back in a minute or two, with the right scores and a link to each source.

How far to trust AI answers: AI for research, by the numbers.

Survey a topic and keep up with it

Add: nothing yet. Type your question in the Sources panel and choose Deep Research.

Ours took about 4 minutes and wrote a report of roughly 4,000 words from 33 sources. Fast Research took about 20 seconds and listed 10, though two papers appeared twice. Fast vs Deep Research

To keep up, add news, papers and posts as they appear, and ask "What changed in these new sources?" KastorFlow imports RSS feeds and refreshes sources on a schedule (Pro). We haven't tested this part, because it plays out over weeks.

Present what you found

Studio turns a notebook into a Slide deck, Infographic, Report, Mind map or Data table. Report templates change with your sources: ours suggested a technical specification and a conceptual explainer.

What the research says about learning a field with AI: sourced statistics

For work

Prepare meetings and sales calls

Add: product specs, notes and call transcripts.

Try: "Write a one-page brief on this account: what they want, what's open, what to ask next." Then make slides from the same sources. A Briefing Doc report gives you an overview with key insights and quotes.

Train and onboard

Add: manuals and procedures.

Try: a Video Overview and a quiz, then click Share and add the new colleague so they can ask their own questions. Notebooks start as Restricted, so only people you add can open them.

When to use something else

• General questions. It says your sources don't cover them and offers web research. The Gemini app is more direct.
• What's on screen in a video. It reads the captions, not the picture. Can it watch videos?
• A whole playlist or channel. Those links don't bring in the videos. Adding a playlist
• Notes you keep for years. Links between notes become plain text, and uploaded notes don't update. NotebookLM vs Obsidian
• Anything private in your notes. Obsidian's hidden comments came through in our upload, so check your files first.
