How to turn NotebookLM slides into an editable PowerPoint deck

You generated a slide deck in NotebookLM from your sources, and now it has to go out as a PowerPoint file, or you need to change things the NotebookLM panel won’t let you touch. This post covers how to download the deck as a .pptx according to Google’s help pages, how to fix slides inside NotebookLM, what to check in the file before you assume it’s editable, and a different way of working when you need full control over the slides.

What NotebookLM does with slides today

According to Google’s help page, decks are created from the “Studio” panel. You pick Slide Deck, choose a format, output language, length and which of the notebook’s sources to use, and describe the deck you want. Generation can take several minutes, and you can keep working in the notebook while it runs.

The same page lists a few conditions. For now the feature is only available to users over 18, and you need edit access to a notebook to generate or delete a deck in it. Google also warns that slide decks are AI-generated and may contain visual or factual inaccuracies.

One detail helps explain what you get back. Google’s December 2025 blog post says NotebookLM designs these slides with Nano Banana Pro, its Gemini image model, together with NotebookLM’s own agents. That’s a good reason to check how much of it you can actually change afterwards.

1. Download the deck as a .pptx file

Since March 2026, according to the Google Workspace Updates blog, NotebookLM can export slide decks as PPTX in addition to PDF. The help page says to open the deck’s three dots menu and pick “Download PowerPoint (.pptx)”. There is one documented exception. If one of the notebook’s sources is a Google Play Books ebook, the publisher’s restrictions may block the download.

Before you plan the rest of your work around that file, check how editable it is. Google’s help doesn’t say whether the text arrives as text boxes you can change. The test takes thirty seconds. Open the file in PowerPoint, click a headline and try typing, then try selecting a single bar in a chart. If you can edit, you have a base to work from in your own tool. If each slide selects as one block and you can’t type inside it, the content is an image, and changes will have to be requested in NotebookLM or rebuilt by hand.

2. Fix the deck inside NotebookLM

If you only need to change a few slides, NotebookLM has a revision mode. Select the deck under “Studio”, choose Revise at the top and type instructions on each slide you want changed. You can ask it to edit text, change layouts or update visuals. Your instructions collect as pending changes, and when you’re done you generate the revised deck. The same mode lets you delete slides and reorder them by dragging thumbnails.

Google’s help page includes three caveats worth knowing up front.

• Every revision creates an entirely new deck, and there are quota limits on the total number of decks you can revise. That’s why Google suggests batching all your changes into one revision.
• For now, revisions don’t take the notebook’s sources into account. If you’re correcting a number, put the right value in your instruction yourself, because NotebookLM won’t look it up in your documents during the revision.
• With Google AI Ultra you can ask NotebookLM to show you an outline before it renders the slides. Feedback on the outline goes in all at once, and after you proceed it can’t be refined further.

This route works for polishing the deck before you download it, as long as you keep working inside NotebookLM.

3. Use NotebookLM for the content and build the slides in your own tool

When the deck has to follow your company template, or you’ll be changing it several times after the first version, it’s more practical to let NotebookLM work through your sources and build the slides yourself. Google’s help says the notebook chat answers from your sources with inline citations, so you can ask it for the content of each slide and see where every figure came from. A request that works well here looks like this:

I’m presenting this quarter’s customer satisfaction survey results to the leadership team, ten minutes. Using this notebook’s sources, give me a list of slide headlines, each one a full sentence stating that slide’s conclusion. Under each headline add no more than four bullets, and next to every number say which source it came from.

You take that outline into PowerPoint or Google Slides and build it on your template. It costs more time than downloading the file, but what you end up with edits like any other deck of yours, and every number stays tied to its source.

Which one fits

• If you need the file today and the editing test passed, download the .pptx and finish it in PowerPoint.
• If the changes are small and you’d rather stay in NotebookLM, use Revise and batch everything into one revision.
• If there’s a corporate template to follow, or the deck will change often, use NotebookLM for the content and build the slides in your own tool.

Before you present

Whichever route you take, check every figure against your original document. Google warns that decks may contain factual inaccuracies, and revisions don’t go back to your sources. Also check that the deck makes the point you need to make in that meeting, on top of what your documents contain. We wrote separately about why AI-generated slides look generic, with five changes that fix it.

Where SlideWeave fits

If what you need today is a .pptx file, the three routes above get you there more directly. SlideWeave’s PowerPoint export is in beta, converts only text, lists, tables and images, and is part of the Pro plan, which is still on a waitlist. It also doesn’t import the .pptx or PDF files you download from NotebookLM.

SlideWeave is built for the deck that gets shared as a link or a PDF and changes often. You paste the outline or key points NotebookLM gave you and describe the deck, get a first draft you edit in a visual editor, and share it by publishing a link or exporting a PDF, both of which the free plan includes. Underneath, each deck is a plain text file that reads almost like a document. Here’s an example we wrote ourselves, a monthly business review for a fictional company with made-up numbers.
