PowerPoint Plagiarism Checker

Think it’s time to start using a PowerPoint plagiarism checker? In 2025, content quality tools for plagiarism checking are a must.

Can plagiarism appear in a PowerPoint presentation? Yes.

Just like plagiarism in a paper, essay, or even blog post, if someone else’s work is copied and put in a PowerPoint presentation without proper credit — even accidentally — it can lead to several consequences of plagiarism, whether in the workplace or academia.

So, a quick plagiarism scan that identifies potential plagiarism? It’s worth it.

How Does a PowerPoint Plagiarism Checker Work?

In short, PowerPoint plagiarism checkers typically scan the text or content of presentation slides to see if it matches any existing material in their databases or online search results. They then generate a plagiarism report with their findings.

A more detailed breakdown of how plagiarism checkers for PowerPoint work might look something like this:

1. The text to be scanned is entered into the tool, usually in one of two ways:
   
   1. Directly uploading the .ppt or .pptx file
   2. Copying and pasting the text from the slides 
2. A plagiarism checking scan is run.
3. During the scan, text is compared against web search results and/or content databases (depending on the tool) to check for similarities. Databases may include academic papers, websites, journals, or other sources.
4. A report is generated with the results. These can look quite different between tools, but Originality.ai’s plagiarism reports include a match score, highlights on flagged text, and links to where it found its matches.

What to Look for in a PowerPoint Plagiarism Detector

Just because plagiarism checkers tend to follow the same general processes for inputting text, it doesn’t mean they’re all just copies of each other. Features offered and technology used can differ from model to model.

So, to help streamline your research, here’s what to look for in a plagiarism detector for PowerPoint.

Quick PowerPoint Plagiarism Detector Checklist:

✓ Accuracy

✓ File compatibility

✓ AI detection capabilities

✓ Source coverage

✓ Paraphrase plagiarism detection

✓ Clear, detailed reports

Accuracy

When plagiarism in the workplace and in high schools can carry such severe consequences, it’s worth investing in a tool with results you can trust. 

Originality.ai’s Plagiarism Checker, for example, is up to 99.5% accurate, surpassing other popular tools. You can find out which ones in our plagiarism accuracy study.

File Compatibility

You can find tools that let you upload .ppt or .pptx files directly, but this could limit your options. Fortunately, most checkers make it easy enough to copy and paste the slideshow text into the tool yourself.

AI Detection Capabilities

Using AI tools isn’t the same as plagiarizing; however, many workplaces, assignments, and educational institutions have clear policies around AI use. 

So, if you want to follow best practice and review a PowerPoint for AI as well, it’s best to look for checkers, like Originality.ai, that allow scans for both AI and plagiarism.

Source coverage

What does the tool’s coverage of sources look like? Where does it look to identify plagiarism matches? 

This can vary depending on the tool. 

Some plagiarism checkers scan specific academic or institutional databases, journal articles, or web search results — or a combination of these sources.

Considering the range of tools available, it’s important to check where your plagiarism detector is scanning for matches.

Paraphrase plagiarism detection

Slideshow text doesn’t usually feature full sentences and paragraphs due to limited space. Instead, it’s reworded or summarized, making the ability to catch paraphrase plagiarism key.

Clear, detailed reports

A good plagiarism report should clearly highlight flagged sections and provide information about matching sources.

With so much to consider, finding the best PowerPoint plagiarism checker among everything out there can take a little time. However, the good news is that it’s basically the longest part of the process.

Actually using the tool you decide on can take just minutes.

How to Check PowerPoint for Plagiarism with Originality.ai

Ready to see what a PowerPoint plagiarism check looks like in action? Using Originality.ai as an example, here’s a breakdown of how to use a PowerPoint plagiarism detector.

Step 1: Enter the PowerPoint slideshow text into the tool

Once you’ve signed up and logged into Originality.ai, it’ll bring you right to the Content Scanner. 

Here, you’ll need to copy and paste the text from your slide(s) into the text box.

For this example, we’re going to use some ChatGPT-generated text for a slide titled “The Impact of Social Media on Consumer Behavior.”

Step 2: Choose your checks and hit “Scan”

Now, look just above the text box to select the different types of checks you’d like to perform. 

Of course, we’re going to check off “Plagiarism check” for our purposes here, but Originality.ai also offers an AI Checker, Fact Checker, Readability Checker, Grammar Checker, and Content Optimizer.

Since there is concern around whether it counts as plagiarism if an AI writes it these days, let’s select the “AI check” option too.

Once you’ve chosen your checks, click “Scan” at the top of the page to start the analysis.

Step 3: Review results

When the scan is complete, an overview of your scores appears at the top of the screen:

For more details on either score, simply click on it. 

Let’s take a closer look at the Plagiarism Checker score:

Here, Originality.ai’s Plagiarism Checker found no plagiarism matches, which makes sense since we used new AI copy for the example. And on that note…

The Challenges With Detecting Plagiarism in PowerPoint

Even with the latest advances in AI and machine learning, the technology for detecting similarities between texts isn’t perfect. 

Here are some of the challenges with detecting plagiarism in PowerPoint:

• False positives. Detectors may flag common phrases or even technical terms as plagiarism, even when they aren’t. This is why it’s so important to manually review any flagged text.
• Issues scanning images and embedded text. Some detectors may let you upload PowerPoint files directly, but that doesn’t mean they’ll extract all of the embedded text or speaker notes correctly. Copying and pasting the text from the slide and into the checker helps to avoid this.
• Paraphrased content is challenging to detect. Reworded or summarized material can be tricky for checkers to catch. Originality.ai, for example, can identify paraphrase plagiarism, but some detectors may struggle to catch it. Learn more about Originality.ai’s plagiarism checking accuracy.
• File size and upload limits. PowerPoint slideshows full of text, images, and animations may exceed upload limits, if the .ppt or .pptx file is accepted by the detector (for Originality.ai, you will need to copy and paste the text from the slide into the checker).

Keep in mind that a human review of the results is essential before officially determining that text has been plagiarized.

How to Create Original Content in a PowerPoint Presentation

So, how can you make your own presentation clear and captivating while still avoiding plagiarism? 

Thoroughly research the topic

Make sure that you fully understand the topic you’re presenting. Gather and organize information from different reputable sources, fact-check, and don’t forget to cite authors. 

Use your experiences and share what you’ve learned to make the presentation uniquely your own. Think about your audience and what they’d find valuable or interesting. 

Go beyond presenting facts

Original content is more than just presenting facts. It incorporates your critical thinking and analysis. Don’t hesitate to dive deeper into what the implications are for what you’re presenting. Draw connections and conclusions between types of information and add your interpretations. This enriches your presentation and makes it more engaging. 

Check for plagiarism before you press play

Before you present, run your presentation (or presentation text) through a PowerPoint Plagiarism checker. Make sure that you’ve properly cited any authors, studies, charts, or other references.
