Google just updated NoteBookLM with a feature that uses Gemini to turn your raw notes into professional slides instantly.

It is fast, free and the results are honestly amazing.

Adverbs of manner

Alright, step one, head over to notebooklm.google.com.

Once you're in, click "Create new notebook".

Now let's quickly name this so we stay organized.

On the left hand side you'll see the prompt box where Gemini is integrated.

And if you click that dropdown, you get two options, Fast Research and Deep Research.

Deep Research is incredibly powerful because it basically does hours of manual work for you.

So for this video, I'm going to select Fast Research just to keep things moving.

So I'm going to type in my topic, AI Automation for Small Businesses and press Enter.

This usually takes a minute or two to scour the web, gather the information and create sources for our notebook.

And now we have a notebook fully populated with credible sources that it pulled automatically.

Now one quick cleanup tip is that if you see any sources highlighted in red, it just means they didn't load properly.

Simply click the three dots right here, select "Delete all failed sources" and you are good to go.

Over here on the right side, you have the Studio panel.

Now there is a lot of power packed into this section, including the Audio Overview and the Video Overview.

Those are honestly incredible features for repurposing content.

But today, we are focusing specifically on the Slide Deck.

So I'm going to find the Slide Deck card and I'm going to press this edit button right here.

And this opens up the Settings panel so we can configure exactly how the slides are generated.

You have Detailed Deck or Presenter Slides.

Detailed Deck gives you text-heavy slides with comprehensive info,

which is perfect if you need to create a standalone report.

This option is much cleaner and more visual.

It gives you just the key points so the audience focuses on you rather than reading a screen.

And right beside that is the length setting, where you can choose between short or default.

This allows the AI to intelligently analyze your content and decide the perfect length automatically.

You can give it custom style instructions.

Since this is using Gemini Nano Banana Pro to generate the slides,

you can tell it exactly how you want them to look.

"Use a modern design with dark backgrounds, clean typography, and professional visuals.

You can customize colors, fonts, the overall aesthetic, whatever you want.

This is how you get slides that match your brand.

Once your settings are ready, click Generate.

Now this takes a couple of minutes to generate.

That might feel long, but it isn't just grabbing stock images and throwing text on slides.

Gemini Nano Banana Pro is creating custom visuals for each slide,

designing the layout and making sure everything looks perfect.

You can see the generated deck card right here.

So I'm going to click on it to open the preview and then hit this expand button to see it in full screen.

These are legitimately professional slides.

The design is clean, the dark mode aesthetic is exactly what I asked for, and

the typography is actually readable and well-placed.

Now, if you want to present these immediately, just click the play button at the top right to open Presentation mode.

You can click anywhere or use your arrow keys to navigate.

And when you're ready, click the download button.

This PDF contains images, not editable text objects.

So if you try to select text or move elements, you can't.

If you need to edit them heavily, you'd have to convert the PDF to Google Slides or PowerPoint separately.

But for most presentations, especially if you're just presenting, this works perfectly.

So that is how you build a presentation from a simple text prompt.

But most of the time, you aren't starting from zero.

Maybe it's a PDF report, a messy transcript from a client meeting, or a dense academic paper.

For that, let's go back to the dashboard.

I'm going to click Create Notebook on the top right to start fresh.

And immediately, you get this panel asking you to upload your content.

Google Docs, text files, direct YouTube video links or PDFs.

For this example, I'm going to upload a PDF.

Let's use this marketing document right here.

This is a dense, text-heavy document that would normally take me hours to summarize manually.

Once that is loaded in, I'm actually not going to jump straight to the slides yet.

Instead, before I generate the deck, I want to use the chat interface to guide the model.

"Identify the top five key statistics from this report and the three biggest risks mentioned."

By having Gemini analyze the document in the chat first,

we are effectively verifying that it understands the core data.

This forces the model to prioritize the numbers we care about.

So let's go back to the Slide Deck panel on the right.

I'm going to click Edit again and this time I'm going to select Detailed Deck.

This ensures we get dense, readable slides suitable for a report rather than just visual cues.

For style instructions, I'm going to type:

White background, blue accents, focus on data visualization and use bullet points for clarity."

Now, it is scanning the entire PDF, extracting the key data points and structuring them into a cohesive layout.
