Why Plagiarism Checks in Google Slides Matter

Even though Google Slides is used mostly for presentations, a lot of original writing lives inside your decks, especially in:

• • Speaker notes
• • Bullet points and supporting content
• • Academic presentations
• • Business reports
• • Conference talks

If you're quoting articles, summarizing research, or using AI tools to help draft your slides, there's a chance your content may not be fully original.
A quick scan helps you stay credible, professional, and protected—especially when you're submitting or presenting to others.

Does Google Slides Have a Plagiarism Checker?

Short answer: No. Google Slides doesn't include any native plagiarism or AI detection tools.
But there's a quick workaround: use the Plagiarism Guard add-on, which integrates directly into your Slides editor. It only takes a couple of minutes to install and start scanning.

How to Run a Plagiarism Check in Google Slides Using Plagiarism Guard

Here's the full step-by-step:

1. 1. Open your presentation in Google Slides
2. 2. Click on Extensions → Get Add-ons
3. 3. Search for "plagiarism"
4. 4. Choose the Plagiarism Guard extension
5. 5. Click Install and give the necessary permissions
6. 6. Once installed, go to Extensions → Plagiarism Guard → Launch
7. 7. Select the text you want to check for plagiarism.
8. 8. Review the results, including the percentage of plagiarism and matching source links

You can run the scan slide-by-slide or review speaker notes and content blocks all within the Slides editor.

The Hidden Risk of Using AI-Generated Content in Slides

AI tools like ChatGPT and Gemini make creating content for slides fast, but speed comes with risk.
Today, more institutions, clients, and events are flagging AI-generated content in presentations. Here's why:

• • Universities treat uncredited AI use as academic misconduct
• • Event organizers reject decks with generic, AI-sounding language
• • Clients and partners distrust robotic, copy-paste phrasing

Even if it's not plagiarized, AI-generated text can still feel flat, repetitive, or inauthentic.
Plagiarism Guard helps by detecting AI patterns and offering instant rewrites via the Humanize feature, so your slides sound more natural and personal.

Detect AI Text and Rewrite It Instantly

Plagiarism Guard doesn't stop at detection—it helps you fix your content too.
Select your text, click on "AI-text checker" button to see how likely it is AI-generated. Then you can click on "Humanize text" and watch it rephrase into clearer, more human language.
Keep editing — all without leaving your deck.

5 Practical Tips to Write More Original Content for Slides

Scanning is smart, but starting with original content saves time and builds credibility. Here’s how to keep your slides fresh, human, and yours:

• 1. Lead with a real insight, not a soft opener
  Skip vague intros like "Let's talk about innovation." Start with a punchy stat, a bold claim, or a contradiction that hooks attention.
  "80% of failed startups had a strategy—they just never used it."


• 2. Explain the "why," not just the "what"
  Original content often comes from your reasoning, not your facts. When citing a study or idea, don't just rephrase it—interpret it. Add a sentence on why it matters or what it changes for your audience.
  Instead of: "Remote work improves productivity."
  Say: "Remote work improves productivity—mainly because people aren't stuck in low-value meetings."


• 3. Add real-world examples
  Originality shows in specifics. Include case studies, personal takeaways, or client outcomes. It's what AI can't fake.


• 4. Break the template habit
  Avoid default slide structures. Use bold headers, one idea per slide, and skip filler like "cutting-edge solutions." Say what you mean.


• 5. Humanize AI-written text before presenting
  If you've used AI to draft content, run it through Plagiarism Guard's Humanize tool. It flags robotic phrases and rewrites them to sound natural.
