01What Google Gemini Notebook LM Is and How It Works

Google Gemini Notebook LM is a new system that puts Notebook LM inside the Gemini app. On April 8th, 2026, Google made this change. It gives you a folder system called Notebooks.

Each Notebook holds your PDFs, Google Docs, past chats, and YouTube links. Gemini remembers everything inside a Notebook forever. You do not have to explain your project every time you open a chat.

The Notebook keeps your files and context ready. When you ask a question, Gemini pulls answers from your own sources, not random web results. This changes how you work with AI because you build your knowledge once and keep using it.

02Main Features of Google Gemini Notebook LM

Here are the main features of Google Gemini Notebook LM:

  • Source limits: Ultra subscribers get 600 sources per Notebook. Pro and Plus get fewer sources. Free users get a smaller cap when the feature rolls out to them.
  • Types of sources: You can add PDFs, Google Docs, files from your computer, website URLs, YouTube videos (their transcripts get indexed), and copied text from anywhere.
  • Custom instructions: You write rules once for a Notebook. You set tone, audience, format, and goals. Both Gemini and Notebook LM follow the same instructions.
  • Source grounding: In Notebook LM, the AI only uses your sources. In Gemini, it can use your sources plus the web. You pick which mode fits your task.
  • Two-way sync: Any source you add in Gemini shows up in Notebook LM, and any source you add in Notebook LM shows up in Gemini. No file transfers needed.

03How to Set Up a Notebook in Gemini

Setting up a Notebook is simple. Follow these steps:

  1. Open the Gemini app on the web. You need a Google AI Ultra, Pro, or Plus account. Free users get access in the next few weeks.
  2. Create a new Notebook by clicking the folder or notebook icon. Name it clearly, like "Q2 Content" or "Sales Calls 2026".
  3. Add your sources. Drop in PDFs, Google Docs, website URLs, YouTube links, or pasted text. Gemini will read and index them.
  4. Write custom instructions. Tell the Notebook who it helps, what tone to use, and what goals to focus on. These instructions apply to both Gemini and Notebook LM.
  5. Turn on "use notebook memory" in the overflow menu. This makes Gemini remember your context across sessions.
  6. Pin up to five notebooks for quick access. Pin the ones you use every day so they sit at the top of your view.

04How to Use Google Gemini Notebook LM With Examples

In this episode, Julian Goldie showed how to use Google Gemini Notebook LM with a real example. He created a Notebook called "AIPB Growth" for the AI Profit Boardroom community. He added the community FAQs, member wins, content calendar, top blog posts, and links to videos that did well.

Then he wrote custom instructions like: "You help me grow our AI automation community. Speak in plain words. Focus on saving members time and getting more leads." After that, every chat inside that Notebook stayed locked in.

Gemini used only those files to answer. Tomorrow he could open the same Notebook and keep working without re-explaining anything.

Another example: To write a fresh email to new members, he used Notebook LM to ask it to summarize the top three member wins from the last month using only the sources. Then he switched to Gemini with the same Notebook and asked it to turn those wins into an email. Gemini used the source material plus its writing skills.

Two tools, one Notebook, one output.

05Results and Comparisons From the Episode

Julian showed that video overviews and infographics are possible with Notebook LM. Users can drop in sources, hit a button, and Notebook LM turns the content into a cinematic video overview or a clean infographic. For example, take all member wins, coaching call topics, and the roadmap, drop them in a Notebook, and ask Notebook LM for an infographic showing the value members get.

This gives you a fresh visual asset for a landing page in minutes, with no designer needed.

Julian also compared Google Gemini Notebook LM to ChatGPT Projects and Claude Projects. ChatGPT and Claude let you group chats and files, but they do not have a research engine like Notebook LM hooked into them. Notebook LM's audio overviews, infographics, and slide decks give Gemini users output formats extending well beyond text summaries.

This makes the Google stack more powerful if you already use Google tools.

06Tips, Limits, and Mistakes to Avoid

Julian shared several tips for getting the most out of Google Gemini Notebook LM:

  • Name your notebooks clearly. Use names like "AIPB Growth" or "Q2 Content". Bad names lead to lost notebooks.
  • Write strong custom instructions. Tell the Notebook who it is helping, what tone to use, and what to focus on. Better instructions mean better answers every time.
  • Clean your sources. Do not dump every file in. Drop in the best stuff: top FAQs, best blog posts, real customer wins. Garbage in, garbage out.
  • Use both apps. Do your daily chat work in Gemini. Use Notebook LM when you want artifacts like audio, video, or infographics. The sync is instant.
  • Pin your top notebooks. Pin up to five for quick access.
  • Add old chats to a Notebook. You can retroactively pull any conversation into a Notebook. Find past research and bring it in instead of starting over.
  • Note that Gemini cannot generate audio overviews, video overviews, infographics, or slide decks. Those features are only in Notebook LM. Use Gemini for chat and Notebook LM for artifacts.

07Who Google Gemini Notebook LM Is For and Why It Matters

Google Gemini Notebook LM is for anyone who works on complex projects and needs AI that remembers their context. It is useful for business owners, content creators, students, and small teams. If you already use Google tools, this stack becomes more powerful because Notebooks sync with Notebook LM.

You save hours every week by not re-explaining your project or re-uploading files. Julian said this changes how you work with AI for good because you build one Notebook and keep using it. The ability to turn sources into video overviews, infographics, and audio overviews without switching apps or re-uploading speeds up content creation.

This matters because it cuts repetitive work and lets you focus on results.
