Imagine you’ve got a folder full of documents, a handful of web pages, some YouTube videos and perhaps a few PDFs.
You’ve got all the information you need.
The problem is finding your way through it.
That’s where Gemini Notebook comes in.
If the name sounds unfamiliar, there’s a good reason.
Until recently, it was called NotebookLM.
Google renamed NotebookLM to Gemini Notebook in July 2026, while keeping its focus on research and understanding information. The change also reflects its growing connection with Google’s wider Gemini ecosystem. (blog.google)
So what exactly is Gemini Notebook, and why should anyone outside a university or research department care?
Let’s have a look.
What is Gemini Notebook?
Gemini Notebook is Google’s AI-powered research and learning tool.
Rather than simply asking an AI a question and accepting whatever information it gives you, you create a notebook around a particular subject and provide it with sources.
Those sources might include:
- 📄 Documents
- 🌐 Websites
- ▶️ YouTube videos
- 📑 PDFs
- 📝 Notes
- 📊 Other information relevant to your project
You can then ask questions about the material and explore the subject through a conversation.
The important part is that your notebook is built around the sources you’ve chosen.
That makes it particularly interesting for research.
Why is that different from a normal AI conversation?
Let’s say you’re researching a historical subject.
You could ask a general AI assistant:
“Tell me about the history of this subject.”
You’ll probably get an answer.
But what if you have ten documents containing information you specifically want to study?
Instead, you can put those sources into a notebook and ask questions based on them.
You could ask:
“What are the three main arguments presented across these documents?”
Or:
“Where do these sources disagree?”
Or even:
“Find the evidence supporting this particular claim.”
That’s a different way of using AI.
You’re not simply asking it to tell you something.
You’re giving it material to work with.
And Google has made it considerably more powerful
This is where Gemini Notebook becomes particularly interesting.
Google upgraded NotebookLM earlier this year with more advanced reasoning, web research, code execution and the ability to produce different types of outputs from your sources. (blog.google)
It can now create things such as:
- 📊 Charts and data visualisations
- 📑 PDF reports
- 📈 Spreadsheets
- 📽️ PowerPoint presentations
- 📝 Documents
- 🖼️ Images
- 📁 Structured data files
You can even ask it to analyse data using code.
That means Gemini Notebook isn’t simply a place to store notes.
It can actually work with the information inside your notebook.
What about the famous Audio Overviews?
This is probably the feature that made NotebookLM famous among many users.
Gemini Notebook can turn your source material into an Audio Overview—essentially an AI-generated discussion about the material.
Imagine you’ve collected several documents about a subject but don’t want to sit down and read every one immediately.
You could listen to an audio discussion of the material while walking, travelling or doing something else.
And Google has continued expanding the format, including Cinematic Video Overviews for eligible users. These can turn source material into more visual video presentations. (blog.google)
That’s a rather different experience from asking an AI chatbot a question.
Could an author use Gemini Notebook?
Absolutely.
This is where I think it gets particularly interesting for writers.
Imagine you’re working on a book.
You could create a notebook containing:
- Research notes
- Historical documents
- Interviews
- Articles
- Character information
- Background material
- Your own notes
You could then ask questions about the material without having to search through every document manually.
For example:
“What information in these sources relates to migration?”
Or:
“Create a timeline from these documents.”
Or:
“Identify areas where my sources contradict each other.”
For a research-heavy writing project, that could save considerable time.
What about students?
Students could use Gemini Notebook to organise material for a particular subject.
Imagine creating a notebook containing:
- Lecture notes
- Course documents
- Research papers
- Websites
- YouTube material
You could then ask Gemini Notebook to explain a difficult concept using those sources.
Google has also been expanding notebooks for learning, including features that help students organise study materials and create personalised learning experiences. (blog.google)
What about business?
There are plenty of possibilities here too.
A small business could create a notebook containing:
- Business plans
- Sales information
- Customer research
- Marketing material
- Competitor information
- Company documents
The owner could then ask questions across the material rather than opening each document individually.
Google has even highlighted examples of businesses using the upgraded NotebookLM to analyse sales and advertising data and produce reports. (blog.google)
Gemini Notebook and Gemini
Here’s where things get even more interesting.
Google has been connecting Gemini Notebook with the Gemini app.
Notebooks can now act as dedicated spaces for ongoing projects, with conversations, instructions and sources kept together. Changes can synchronise between Gemini and Gemini Notebook. (blog.google)
So instead of starting from scratch every time you return to a project, you can continue working with the same collection of information.
Think of it as giving your AI assistant a desk with all the relevant paperwork already sitting on it.
Is Gemini Notebook free?
This is where we need to be careful.
Google has been making different features available to different groups and subscription levels, so access to the more advanced capabilities can depend on your Google AI plan or Workspace account.
Some core NotebookLM/Gemini Notebook functionality is available more broadly, while features such as advanced research, code execution and certain higher-end capabilities have been rolling out to Google AI subscribers and eligible Workspace users. (blog.google)
So before paying for anything, I’d recommend trying the version available to you first.
The Pros
📚 Excellent for source-based research
You provide the material, then explore it with AI.
🔎 Keeps your research together
Instead of jumping between numerous documents and browser tabs, you can organise the material around a particular project.
🎧 Audio Overviews
Useful if you’d rather listen to your material being discussed than immediately read everything.
📊 Can work with data
The newer capabilities allow deeper analysis, including code execution and data visualisations. (blog.google)
📑 Creates useful outputs
Reports, presentations, spreadsheets and other formats can be generated from your sources.
🔗 Increasingly connected to Gemini
Your notebooks can now work across parts of Google’s AI ecosystem. (blog.google)
The Cons
It can feel complicated at first.
There are quite a few features, and understanding what each one does takes a little experimentation.
Not everything is available to everyone.
Some of the more advanced capabilities depend on your plan or account.
Your sources still matter.
If the information you provide is incomplete, inaccurate or biased, the resulting analysis can reflect those limitations.
AI can still make mistakes.
Even when working from your own sources, important information should be checked.
My Verdict
I think Gemini Notebook is one of the more interesting tools we’ve looked at in the AI Toolbox so far.
Not because it is another chatbot.
It isn’t really about having a conversation with AI for the sake of having a conversation.
Its strength is giving AI something substantial to work with.
Documents.
Research.
Notes.
Data.
Videos.
Web pages.
Then asking it to help you make sense of all of it.
And the recent move from NotebookLM to Gemini Notebook suggests Google sees this as something much bigger than a standalone note-taking experiment. (blog.google)
For researchers, students, writers and anyone who regularly works with large amounts of information, this is definitely one I’d put in the toolbox.
Final Thoughts
We’ve now looked at six different AI tools.
ChatGPT.
Perplexity AI.
Canva AI.
Claude.
Gemini.
And now Gemini Notebook.
There’s a pattern emerging.
The most useful AI tools aren’t necessarily the ones that simply produce the cleverest answer.
Sometimes the real value comes from giving AI the right information and the right job.
That’s what makes Gemini Notebook worth trying.
If you have a collection of documents sitting on your computer that you’ve been meaning to understand, organise or analyse, perhaps this is the week to give it a try.
Have you used NotebookLM—or its new name, Gemini Notebook?
If you have, I’d love to know what you used it for.
If you haven’t, what would you put into your first notebook?
