Why Google Slides need a file-based AI check
A Google Slides deck is short bullets, pictures and speaker notes. Copying the text out loses the notes and the images, and a link cannot be read by an outside tool because the deck is private to your account.
Gemini in Google Slides can now generate images and whole slides, so a deck can mix your own writing, generated pictures and stock photos. Each part needs its own check.
Downloading the deck as .pptx keeps the slides, notes and images together. AnyFact reads all of them and shows which slides drove the verdict, so you can see whether it was the text, the notes or a picture.
Does this sound familiar?
- You built your class presentation in Google Slides and want to check it before you present.
- A group deck mixes several writers and you want to see which slides stand out.
- You used Gemini to create images for your slides and want to see how they read to a detector.
- You review student presentations made in Google Slides and need more than a gut feeling.
Here's what we check
Upload the file
PDF, DOCX or PPTX, up to 20 MB and 50 pages.
Text, images, metadata
Each part goes to the right detector; unusual authoring software or dates are flagged.
A verdict in three levels
Probably human, uncertain or probably AI — never a bare percentage — with a short explanation and the limits of the method.
How to read the result
The signals point to a person. It is not a guarantee: a careful generator or heavy editing can leave few traces.
The signals disagree or are too weak. We say so rather than guess, and list what was found.
The signals point to generation. It is an indication, not proof — check the context before acting.
Sample layout. Real reports name the signals that were checked and the limits of the method.
What does a Google Slides AI detector check?
A Google Slides AI detector checks the deck you download from Google Slides. Choose File > Download > Microsoft PowerPoint (.pptx) and upload the file: AnyFact reads the text of every shape on every slide, tables and grouped shapes included, the speaker notes, the images and the metadata, then gives a result slide by slide with an overall verdict of probably human, uncertain, probably AI or mixed.
Presentations are the format people check most with AnyFact: of the first 112 documents analysed in the beta, 50 were PowerPoint files, against 31 Word files and 30 PDFs, most of them coursework that students were checking themselves. A .pptx downloaded from Google Slides is read exactly like one saved from PowerPoint, as the AI detector for PowerPoint page explains.
How to check Google Slides for AI, step by step
- 01Open the presentation in Google Slides and choose File > Download > Microsoft PowerPoint (.pptx).
- 02Open the downloaded file in PowerPoint, Keynote or another viewer and check that your speaker notes are there: notes are often the longest text in a deck.
- 03Check the limits: up to 50 slides and 20 MB. For a heavy deck, remove unused slides or split it.
- 04Upload the .pptx to the AI document detector. It uses 3 credits; a free account gets 10 a month.
- 05Read the overall verdict, then go slide by slide: was it the text, the notes, an image or the metadata?
- 06Open the deck’s version history in Google Slides (File > Version history > See version history) next to the flagged slides.
- 07Download the PDF report. If you believe the result is wrong, report it with the “the result is wrong” button.
.pptx or PDF: which Google Slides download should you check?
| Download | What an AI check can use | Result given |
|---|---|---|
| Microsoft PowerPoint (.pptx) | Text of every shape and table, speaker notes, images, metadata | Slide by slide: the most complete check |
| PDF Document (.pdf) | Only what is on each page: the slide text and images; speaker notes only if they were printed onto the pages | Page by page |
| Image of a slide (PNG, JPEG) | One picture: the text becomes pixels | One verdict for the image, in the AI image detector |
Choose .pptx unless you need to check the exact PDF you will hand in. The AI PDF checker explains what a PDF keeps and loses.
What does an AI checker read in a Google Slides deck?
AnyFact reads the slide text, the tables, the speaker notes, the images and the metadata of the .pptx. The table shows where each part appears in the result.
| Part of the deck | What is checked | How it shows in the result |
|---|---|---|
| Text in shapes and tables | Titles, text boxes, placeholders, grouped shapes and table cells on every slide | Scored as the deck’s text; flagged text shows on its slide |
| Speaker notes | The notes under each slide | Scored as text; often the longest passages in a deck |
| Slide images | Up to 30 images per deck go through the photo detector; icons, logos and thin lines are skipped | Images that look generated are flagged on their slide |
| Provenance on images | C2PA credentials or metadata naming an AI generator, when an image still carries them | Listed as a signal on the slide |
| Deck metadata | The software fields, the dates and the recorded editing time | Listed as signals, each with what it can and cannot mean |
Why a Google Slides deck gives the text check little to work with
A deck of 15 slides with a title and four bullets each is a few hundred words, close to the 300 words below which the result says the text check gives little evidence. Text is scored in blocks of about 1,000 words, so the bullets of several slides are read together. Speaker notes, images and the slide-by-slide view then carry much of the weight, which is why a deck downloaded without its notes says less.
Text inside a picture, such as a screenshot of a paragraph or an infographic, is checked as an image, not read as text.
Gemini in Google Slides: AI images, generated slides and Content Credentials
Gemini can now create images and slides inside Google Slides, so a deck can contain AI images its author generated in a few clicks. Google’s help pages describe it this way:
- Images: in Slides, Insert > Help me visualize > Image, then a prompt in the side panel. Google says the feature uses its Gemini 3 Pro image model, requires an eligible Google Workspace or Google AI plan, and that generated images are for use only within Slides and Vids.
- Slides: a “Create a slide” feature, in beta, generates a whole slide from the content of the active slide.
- Labels: Google’s help page on AI labels says images generated by Gemini in supported Workspace apps carry Content Credentials. In Slides on the web, right-click the image and open the Content credentials sidebar to see them.
The same Google page warns that the record can be broken: by a screenshot, by resizing or re-saving the image in another editor, by some platforms and tools, and by downloading or exporting the file. So check the credentials in Google Slides itself when you have the deck, and do not read their absence in the download as a sign that the image is real.
AnyFact reads C2PA credentials and metadata on each slide image when they are still in the .pptx, and lists an image that declares an AI generator on its slide. Otherwise the photo detector scores the image. Google’s SynthID watermark, which its help page says is preserved during most edits, downloads and exports, is not read by AnyFact; our guide what is SynthID? explains how to check for it, and what are C2PA content credentials? explains the credentials themselves.

What the metadata and the version history of a Google Slides deck can tell you
The downloaded file says little about how the deck was made; the version history in Google Slides says much more.
| What you find | What it suggests | What it does not tell you |
|---|---|---|
| 0 minutes of recorded editing time in the .pptx | The file was written by Google’s export, not edited in PowerPoint | Anything about AI: it is common for a download |
| An AI slide tool named in the metadata (Gamma, Tome, SlidesGPT…) | The file was made or exported by that tool | Whether the content is the presenter’s own; and a deck imported into Google Slides and downloaded again can lose this trace |
| Slides that appear all at once in the version history | Slides were imported or pasted from another file or tool | Which tool, or whether the presenter made them elsewhere |
| Slides that grow over several sessions in the version history | A working process: drafting, rearranging, rewriting | Who wrote the notes, if several people edited |
To open the history, choose File > Version history > See version history, or select Last edit at the top right. As with Google Docs, you need permission to edit the file to see it, and you can name key versions so that a reviewer finds them quickly. The AI detector for PowerPoint page covers metadata signals in more depth.
How to read the slide-by-slide result for a Google Slides deck
Look at which slides were flagged and by which part of the check: slide text, speaker notes, images or metadata. In a Google Slides deck, each pattern points to a different question.
| What you see | Likely reading | What to do next |
|---|---|---|
| Only images flagged | Generated illustrations, for example made with Gemini in Slides, in a deck whose text reads as human | Check the image’s Content credentials sidebar in Google Slides, and whether AI images were allowed and credited |
| Speaker notes flagged, slides not | The script was drafted or polished with an assistant | If it is your deck, keep the drafts of your notes; if not, ask the presenter to talk through those slides |
| A few slides flagged in a group deck | Different writers, or slides imported from another file or tool | Use the version history to see who added those slides, and when |
| An AI slide tool named in the metadata | The deck was made or exported by that tool before it reached Google Slides | Ask how the tool was used: design only, or content too |
| Mostly uncertain, or “little evidence” on the text | Short bullets and many images give thin evidence | Treat it as “no clear signal”, and rely on the notes, the history and the presenter’s explanation |
When the score falls in the grey zone, Claude, Anthropic’s model, reviews the content as a second opinion. It can move the score only a little and never decides alone. For the visual signs of generated pictures, see how to tell if an image is AI-generated.
What are the limits of a Google Slides AI detector?
A Google Slides AI detector gives an indication, not proof, on a format with little text.
- AnyFact cannot read a Google Slides link: download the .pptx first.
- Up to 50 slides and 20 MB per file; up to 30 images per deck are checked.
- Short bullets give thin evidence, and under 300 words of text the result says so.
- A PDF holds only what is on its pages, so speaker notes are usually missing from it; a .pptx keeps them with each slide.
- Content Credentials on Gemini images can be lost on download, and missing credentials prove nothing.
- Compressed or heavily edited images are harder for every image detector.
- Translated slides and slides by non-native writers are harder to judge.
- Detectors disagree, and no detector predicts what Turnitin or your school’s own tool will say. See are AI detectors accurate?.
Checking a Google Slides presentation as a student or a teacher
- Students: keep the deck in one Google Slides file so that its version history covers your work, and name the key versions.
- Students: credit your images on the slide or on a sources slide, and if you generated any with Gemini and your course allows it, say so.
- Students: in a group deck, note who made which slides; questions about a slide are then quick to answer.
- Teachers: ask for the .pptx rather than a PDF, so that the notes and images are included, and read the result slide by slide.
- Teachers: ask the student to present or explain the flagged slides, and never sanction on a detector result alone.

Before you check
Is the result proof that a content was made by AI?▼
No. It is an indication, not proof. Detectors can be wrong in both directions, especially on compressed, cropped, edited or very short content. Use the result to decide what to check next, not as a final judgement on anyone.
Why no percentage?▼
A single percentage suggests a precision no detector has. You get one of three levels — probably human, uncertain or probably AI — with the signals behind it and the limits of the method.
How does the analysis work?▼
When the content carries provenance data, such as C2PA content credentials or metadata, we read it first. Then an open-source detector scores the content. When the score is borderline, Claude reviews it as a second opinion, and the result is explained in plain words.
What happens to my files?▼
They are processed to run your analysis — including, for borderline cases, a review by Claude, Anthropic’s model — and deleted after 30 days.
What does it cost?▼
There is a free plan: a free account gets 10 credits every month, with no credit card. Pro ($15 a month) gives 1,000 credits a month; Business ($49 a month) gives unlimited Business Checks and AI checks under a fair-use limit.
Is there an AI detector for Google Slides?▼
Yes, by downloading the deck. In Google Slides, use File > Download > Microsoft PowerPoint (.pptx), then upload the file to AnyFact’s document detector. It reads every slide, the speaker notes and the images, and gives a result slide by slide.
Can you check a Google Slides link for AI?▼
Not with AnyFact. Google Slides presentations are private to your account by default, so an outside tool cannot read them from a link. Download the .pptx and upload it.
Does the check read my speaker notes?▼
Yes, when you upload the .pptx: the speaker notes are read and scored with the text of every shape and table. Open the downloaded file first to make sure your notes are there. A PDF holds only what is on its pages, so use the .pptx.
Can it detect images made with Gemini in Google Slides?▼
Often, but not always. If an image still carries Content Credentials or metadata naming an AI generator, AnyFact lists it on its slide. Google warns that downloading or exporting can break those credentials; the photo detector then scores the image and explains the verdict.
How many credits does a Google Slides check use?▼
A .pptx or PDF uses 3 credits, for up to 50 slides and 20 MB. A free account gets 10 credits a month, with no credit card.
Why does my Google Slides deck get an uncertain result?▼
Slides hold little text: short bullets and many images give the text check thin evidence, and under 300 words the result says so. Uncertain means no clear signal, not a hidden “probably AI”.
Will the result predict what Turnitin says about my slides?▼
No. Turnitin and other school tools are separate systems, and AnyFact does not replicate or predict them. The result shows how your deck reads to AnyFact’s detectors, with the reasons.
