NotebookLM Slides to Editable PowerPoint (Gemini Notebook, 2026)

Disclosure: NOXI publishes this guide, and rebuilding in NOXI is one of the four options we describe. We didn't run hands-on tests for this article. The facts about Gemini Notebook come from Google's help pages and announcements, checked on 25 September 2026. Where we rely on independent guides, we say so. We explain where each option is the better choice, including the ones that aren't NOXI.

What a NotebookLM Slide Deck is, and who this guide is for

A Slide Deck is a presentation that Gemini Notebook generates from the sources in a notebook. It's built for reading and presenting as-is, not for editing afterwards.

Google offers two formats. A Detailed Deck is "a comprehensive deck with full text and details", good for sending as a read-ahead. Presenter Slides are "clean, visual slide decks with key talking points", for presenting. You can also choose the output language, the length (short, default or long) and add a prompt describing the audience, style and focus. Google says generation can take several minutes and warns that decks "may contain visual or factual inaccuracies."

This guide is for anyone who likes their NotebookLM deck and has just found they can't change a word of it in PowerPoint: students, consultants on a client template, teachers updating last year's figures, managers asked to "just tweak slide 6".

How to export NotebookLM slides to PowerPoint (the built-in way)

The export itself takes three clicks. It's built into Gemini Notebook for everyone who can create Slide Decks.

1. Open your notebook and generate a Slide Deck from the Studio panel. To set the format, language, length and a prompt first, use the pencil icon.
2. When the deck is ready, open the three-dot menu next to it.
3. Choose Download PowerPoint (.pptx), or Download PDF Document (.pdf).

You can also present the deck full screen with Start slideshow, or share it via a link (personal accounts) or by sharing the notebook.

What changed in 2026

• 20 November 2025: Slide Decks launched in NotebookLM, powered by Nano Banana Pro. At first you could share them only as a PDF.
• 18 February 2026: Google added slide-level revisions by prompt and PPTX export, rolling out first to Google AI Pro and Ultra subscribers.
• 20 March 2026: Google Workspace Updates confirmed both features for all Workspace customers and personal Google accounts with NotebookLM access.
• 16 July 2026: NotebookLM was renamed Gemini Notebook: the same standalone research product, now also visible inside the Gemini app, with old links redirecting automatically.
• 2 September 2026: new usage limits for Gemini Notebook took effect (see the limits section below).

The rename doesn't change the export. "NotebookLM slides", "Gemini Notebook slide deck" and "Gemini Notebook presentation" all refer to the same feature. One detail matters here: the Gemini app can chat with your notebooks, but Google's help page says Studio outputs such as Slide Decks are made only in Gemini Notebook itself.

Why NotebookLM slides aren't editable

They aren't editable because each slide is generated as a picture. The PPTX export puts those pictures into a PowerPoint file, but it doesn't turn them back into text boxes, shapes and charts.

Most slide tools assemble a slide from separate objects: title and text boxes, shapes, images and a chart with data behind it. Nano Banana Pro is an image-generation model, so it composes the slide the way it composes any image: headline, bullets, icons, chart and background come out as one set of pixels. That's also why the decks look so polished — nothing constrains the design to a template.

It also means a .pptx container can't recover what was never there. Independent guides that took the exported file apart describe the same result: one picture per slide, no text boxes, and no chart data underneath. Google's help page doesn't describe the file's internals, but you can check it yourself in ten seconds:

• Click a headline. If the whole slide gets a selection frame and the ribbon shows Picture Format instead of Shape Format, the slide is an image.
• Press Ctrl+F (Cmd+F on a Mac) and search for a word you can see on the slide. PowerPoint won't find it.
• Open the Selection Pane (Home › Arrange › Selection Pane). You'll see one picture per slide and nothing else.

There's a second trade-off. Gemini Notebook's chat answers carry inline citations that link to the exact passage in your sources. Google's Slide Deck documentation describes no equivalent on the slides, so a figure on a slide is harder to trace than the same figure in chat.

NotebookLM slide limits on the free plan

Google doesn't publish an exact number of Slide Decks for any plan. Its help page lists Slide Decks and revisions as "Limited" on the free Standard plan, rising to "More", "High", "Higher" and "Highest" limits on paid plans.

From Google's Gemini Notebook upgrade page, reflecting the limits that took effect on 2 September 2026. "Plus", "Pro" and "Ultra" are Google AI plans, and Ultra has two storage tiers with different limits. Workspace editions have their own limits.

Also useful: each source can be up to 500,000 words or a 200 MB upload, and Slide Decks need an account verified as 18 or older. Revisions count against the same quota, so Google recommends batching changes into one revision. Per-day deck numbers quoted on third-party sites are estimates, not Google's figures.

Four ways to turn NotebookLM slides into an editable PowerPoint

There are four realistic routes. They trade off keeping NotebookLM's look against having a deck you can actually edit, update and brand.

A chart painted by an image model is a picture with no data behind it, and patching or OCR can't change that. NOXI rebuilds each chart from your real data, and it reaches PowerPoint exactly as designed. Each route is described in detail below.

Option 1 — Keep the images and patch them

If the deck is 95% right and it's being read rather than maintained, the fastest fix is to leave the slides as images and cover the mistakes.

How: in PowerPoint, draw a rectangle filled with the slide's background colour over the wrong text (use the eyedropper to match the colour), then add a text box on top in a similar font. For bigger problems, use Gemini Notebook's own revision: open the deck, click the pencil icon, write instructions for every slide you want changed, and generate one revised deck. Some people also take a slide image into the Gemini app's image editing, ask it to correct a label, and paste the fixed image back.

Good for: a one-off read-ahead, a class handout or an internal summary that nobody will update.

Where it breaks: patches show when projected, especially on gradients. The deck can't be searched or read by screen readers, won't follow a corporate template, and next quarter you'll be patching patches. A regenerated slide is redrawn from scratch, so check nothing else changed.

Option 2 — OCR "convert to editable" tools

OCR converters read the text in each slide image and place real text boxes over a cleaned-up background. They're the best way to keep NotebookLM's visual style while getting text you can type into.

A whole category of tools does this job, often named after NotebookLM itself — for example DeckEdit, Codia NoteSlide and SlidesPilot — and general PDF-to-PowerPoint converters with OCR work similarly. You upload the PDF or PPTX; the tool detects each block of text, estimates its position, size and font, removes the text from the image (some "inpaint" the background where the letters were), and rebuilds the slide as a background picture with editable text boxes on top.

What they do well

• They keep the look. Illustrations, colours and composition stay, because they're part of the background image.
• They're quick. The whole deck is converted at once, and you can then fix a typo, translate a headline or update a date.
• Some run locally. A few process files in your browser, which matters for confidential sources. Read the privacy notes before uploading.

Their limits (the category, not any one vendor)

• Fragmented text boxes. OCR sees lines, not paragraphs. A three-line bullet can become three separate boxes, so editing one line doesn't reflow the others.
• Font guesses. The tool matches the painted lettering to the nearest available font. Sizes and weights come out close but not identical, and a longer word may overflow its box.
• Charts and diagrams stay pictures. A bar chart painted by an image model has no data behind it. OCR can recover the labels but not an editable chart, so to change a number you redraw the bar.
• Ghosts and artefacts. Where the text was removed, busy backgrounds can show smudges once you type something shorter.
• OCR errors. Small text, stylised headings and non-Latin scripts are misread more often, so proofread every slide. Check right-to-left languages such as Arabic especially carefully.
• The content doesn't improve. A figure the image model got wrong is now editable, but still wrong until you check it against your sources.

Option 3 — Rebuild a native deck from the same sources in NOXI

Rebuilding means you don't convert the pictures at all. You give the same source files to a tool that builds slides from real objects, so every heading, table and label is editable from the start.

Choose this route when the deck has a future: you'll present it, send it to a client, brand it or update it. NOXI is a free AI presentation maker that, like Gemini Notebook, works from your materials — the same PDFs, Word files, notes, data and images. The difference is what comes out.

• Native slides, not pictures. Every text element is live text in NOXI's editor, and it stays live text in the exported .pptx.
• Sources on the slides. Many people chose NotebookLM because answers are grounded in their sources. NOXI keeps that habit on the slide itself: when it researches the context around your files, it puts the source link for each figure on the slide. You can also ask it to name which of your documents a figure came from. More on this in our guide to AI presentations with research and citations.
• Analytical layouts. Instead of one illustrated composition per slide, you get consulting-grade structures: strategy houses, funnels, Gantt charts and timelines, scorecards, comparison tables and data charts. See consulting-style slides for how these work.
• Two ways to edit. Ask in chat ("simplify this slide", "turn this into a timeline") or drag and resize by hand in a presentation editor. Brand templates apply your fonts and colours.
• Free, including the models. Claude Opus and GPT-5.5 write the content; Nano Banana Pro — the same image model — draws per-slide illustrations, not the text. No watermark, no export paywall.

Keep the look, too. Upload the NotebookLM PDF or PPTX itself, or your own template, and NOXI generates the new deck in that style, with live text instead of pictures. Almost no other AI presentation tool can build a deck in the style of any file you give it. For turning long documents into slides in general, see PDF to presentation with AI.

Option 4 — Gemini in Google Slides (the Google route)

If you're on an eligible paid Google plan and work in English, Gemini can now build a full, native Google Slides deck, which you can then download as a .pptx.

Since 30 June 2026, Gemini in Google Slides can generate a full multi-slide presentation from one prompt, grounded in Drive files, Gmail and chats, optionally in the style of an existing deck; Google calls the result "fully editable slides". Put your NotebookLM source files in Drive, reference them in the prompt, then use File › Download › Microsoft PowerPoint. A second path is Canvas in the Gemini app: ask it to "create a presentation" from uploaded files, then select Export to Slides.

The catches: full-deck generation in Slides is English (United States) only at launch. It requires Business Standard or Plus, Enterprise Standard or Plus, Google AI Pro or Ultra, AI Pro for Education or the AI Expanded Access add-on. Canvas presentations were announced for Workspace editions and Google AI Pro and Ultra. Neither path documents sources on the slides, the design follows Slides themes, and Google fonts may be missing where the .pptx is opened, so check it in PowerPoint first.

Which option should you choose?

Choose based on what happens to the deck next. If nobody edits it, patch it. If you need the look, convert it. If you'll present, brand or update it, rebuild it.

A combined workflow works well: use Gemini Notebook for what it does best — reading many sources and answering with citations — and build the presentation in a tool made for presentations. The next sections show how.

Rebuilding slide by slide: what each NotebookLM slide becomes

NotebookLM decks tend to use a handful of recurring slide types. Each one has a native equivalent that's easier to edit and usually clearer to present.

Two rules apply throughout. Take numbers from the source, never from the slide image — an image model can mis-draw axes and labels, and chat citations take you straight to the passage. And write action titles: a sentence stating the conclusion ("Churn fell after the pricing change"), not a label ("Churn").

Worked example: a 15-slide NotebookLM deck rebuilt for a leadership review

This example is illustrative. The scenario is invented to show the method, and the bracketed values stand in for your own figures.

Situation. A product manager's notebook holds two industry reports (PDF), customer interview notes (Google Doc), a competitor's pricing page, an internal usage export and a conference talk (YouTube). NotebookLM's Presenter Slides look great, but leadership wants the deck on the company template, with this month's usage numbers and a clear recommendation — and none of the text can be edited.

Step 1: get the outline out of the notebook. In Gemini Notebook's chat, she asks for a slide-by-slide outline with a citation for every figure (see prompt 1 below) and saves the answer as a note. She checks three figures by clicking their citations.

Step 2: rebuild in NOXI. She uploads the two PDFs, the interview notes (exported as Word) and the usage export, pastes the outline, and uses prompt 4. NOXI proposes 11 slides:

Step 3: edit and check. She applies the brand template, asks NOXI to "merge slides 4 and 5: chart on the left, two quotes on the right", and drags the quotes into place by hand. She opens every source link on slides 3 and 6 and corrects one figure taken from an older report.

Step 4: export. She downloads the .pptx, runs the checklist below and sends it: live text, embedded fonts, the slides exactly as she approved them — nothing to OCR, nothing to patch.

Step by step: from NotebookLM sources to an editable deck in NOXI

The whole rebuild follows seven steps. It starts from the files you already fed Gemini Notebook, not from the exported images.

Ready prompts for NotebookLM and NOXI

These prompts cover both halves of the job: getting a better outline or deck out of Gemini Notebook, and rebuilding it natively. Replace the square brackets with your own details.

What a real PowerPoint export looks like: NOXI's own engine

A NOXI export is a real PowerPoint file: every slide is rebuilt as PowerPoint objects by NOXI's own export engine. It isn't a set of pictures in a .pptx wrapper, and it isn't a PDF run through a converter.

Why this is rare

The NotebookLM problem is an extreme version of a common one. Most AI slide tools design in a web format, while PowerPoint uses fixed 16:9 slides, its own text-box rules and fonts that must be installed or embedded. To bridge the gap, many tools export a picture of each slide or push a PDF through a converter — hence uneditable slides, headings split line by line, swapped fonts and repair prompts.

What you get from NOXI

• The file matches the approved slide: same layout, spacing, colours and typography, on real 16:9 slides.
• Text is live. Click any heading or paragraph and type. Search, spell-check and screen readers all work.
• Fonts travel inside the file. They're embedded, Arabic included, so letters stay connected and right-to-left layouts are kept, even on a computer without those fonts.
• Images keep their original quality, and PowerPoint opens the file without a repair prompt.

That's the point of leaving NotebookLM's export: the file you send opens looking identical and stays editable. Almost no other AI presentation tool produces a pixel-perfect PowerPoint like this. Which generators produce a real .pptx is covered in our AI PowerPoint generator guide.

Checklist: is your "editable" PPTX really editable?

Whichever route you took, OCR, Google or NOXI, spend five minutes on these checks in desktop PowerPoint before you send the file.

Common mistakes when moving NotebookLM slides to PowerPoint

• Assuming .pptx means editable. The format says nothing about what's inside. Run check 1 above before promising edits.
• Copying numbers from the slide image. Take them from the source passage via the chat citations.
• Burning the free quota on single-slide fixes. Batch every change into one revision (prompt 3).
• Expecting revisions to re-check sources. Google says they don't.
• OCR-converting a deck you'll maintain. Line-by-line boxes over a picture get harder to edit every month. Rebuild once instead.
• Presenting a Detailed Deck. It's written to be read. Cut to action titles and move detail into speaker notes.

Frequently asked questions

Can you convert NotebookLM slides to PowerPoint?

Yes. Since February 2026, Gemini Notebook, formerly NotebookLM, can download a Slide Deck as a PowerPoint (.pptx) file from the three-dot menu next to the deck. The file opens in PowerPoint, but each slide is a single image, so you can present it but not edit the text.

Why are NotebookLM slides not editable?

Slide Decks are generated by Nano Banana Pro, Google's image model, which paints each slide's headline, text, icons and chart into one picture. The PPTX export places those pictures into PowerPoint slides without turning them back into text boxes, shapes or charts, so there is no text in the file to edit.

How do I make NotebookLM slides editable in PowerPoint?

Use an OCR converter to keep the look, with editable but fragmented text boxes and approximate fonts. Or rebuild the deck from the same source files in a tool that exports native slides, such as NOXI, for live text throughout. Gemini in Google Slides also builds native slides on eligible paid plans, in English (US) only.

Is NotebookLM now called Gemini Notebook?

Yes. Google renamed NotebookLM to Gemini Notebook on 16 July 2026. It is the same standalone research product, old links redirect automatically, and Slide Decks with PDF and PPTX download work as before. Slide Decks are created in Gemini Notebook itself, not in the Gemini app.

How many slide decks can I make with NotebookLM for free?

Google doesn't publish an exact number. Its help page lists Slide Decks and revisions as Limited on the free Standard plan and gives progressively higher limits on Plus, Pro and Ultra. Revisions count against the same quota, so batch your changes. Slide Decks also require a Google account verified as 18 or older.

Can I export NotebookLM slides to Google Slides?

Gemini Notebook offers PDF and PPTX downloads. You can import the PPTX into Google Slides, but the slides remain images. For native, editable Google Slides, use Gemini in Google Slides or Canvas in the Gemini app with your source files, which needs an eligible paid plan, or build the deck elsewhere and import an editable .pptx.

Do NotebookLM to editable PPTX converters work?

They work for keeping the look: OCR reads the text in each slide image and places real text boxes over the background, so you can fix typos and dates. Expect fragmented boxes, approximate fonts, misread characters and charts that remain pictures. Proofread every slide, and avoid them for decks you update often.

What is a good prompt for NotebookLM slides?

Name the audience, format and constraints: for example, Presenter Slides for a leadership team, one idea per slide, headlines under eight words, at most three bullets, a flat style in your brand colour, numbers labelled with their source document, and a final slide with one next step.

Can I edit a single slide in NotebookLM?

Yes, by prompt. Open the deck, write revision instructions for any slides you want changed, and generate a revised deck. Google notes that sources are not taken into account during revisions and that revised decks count against a quota, so batch all changes into one pass and check figures against your sources.

What is the best free way to get an editable deck from my NotebookLM sources?

Upload the same source files to NOXI, a free AI presentation maker, optionally with an outline from Gemini Notebook's chat. It builds native slides with live text and sources on the slides, and exports a real PowerPoint with embedded fonts that matches the approved slides exactly.
