Nearly 50% of U.S. adults are reported to be using generative AI for tasks like writing, brainstorming, or research, and the number is only climbing.
With so much AI-generated content floating around, plagiarism has taken on a new form.
Traditionally, plagiarism meant copy-pasting from a source on the internet, however, with AI tools, anything that comes straight from an AI output without editing for a human-like tone is counted as AI plagiarism in some cases.
And that comes with real consequences like academic penalties, SEO issues, and damaged reputations.
An AI plagiarism checker tool counters this problem.
In this article, we’ll break down what an AI plagiarism checker actually is, how to use it, some of its benefits, and the best practices to get the most out of it.
Let’s dive right in.
Key Takeaways
- An AI plagiarism checker is useful for everyone who writes, e.g., students, educators, researchers, and content creators.
- Undetectable plagiarism and AI checker is free to use, detects outputs from multiple AI models at once, and has an award-winning accuracy (97–99.6%). Plus, it includes a Humanizer to rewrite flagged text into more natural, human-like phrasing.
- To use the AI plagiarism checker, you just need to copy and paste your text into the checker, click “Check AI Plagiarism,” and get a detailed report within seconds.
What Is the AI Plagiarism Checker?
An AI plagiarism checker is a piece of software designed to sniff out copied or overly similar text in writing.
It scans massive databases, journals, websites, and previously submitted work to see if your text has popped up somewhere before.
Old-school plagiarism checkers used to only match exact phrases.
Never Worry About AI Detecting Your Texts Again. Undetectable AI Can Help You:
- Make your AI assisted writing appear human-like.
- Bypass all major AI detection tools with just one click.
- Use AI safely and confidently in school and work.
The ‘AI’ part in these modern solutions is capable of recognizing paraphrased content and rewritten sentences as well.
AI plagiarism checkers work in a pretty simple way.
You upload or paste your text, the system runs it through its algorithms, and within seconds you get a report that tells you the following:
- What percentage of your text looks original
- Which parts match existing sources
- Links to those sources so you can double-check
Who Should Use It?
If you ask me briefly, anyone who writes should use an AI plagiarism checker.
In particular, anyone who wants their words to actually be theirs and not accidentally borrowed from the depths of the internet really needs one.
We all know academic integrity policies are pretty strict. Universities use plagiarism checkers all the time, so students should too.
Even if you didn’t copy, you will be surprised how easily your phrasing overlaps with a paper written five years ago in another country, so you better find it out yourself before your professor does.
Teachers and professors obviously also use it to check the originality of the content submitted by students.
But researchers need it the most. Plagiarism can end careers in academia since journals and peer reviewers use these tools religiously.
Similarly, if you write on the internet, i.e., blogs, marketing copy, SEO articles, social media posts, etc, an AI plagiarism software will ensure you don’t accidentally repeat what’s already out there.
How It Differs From Traditional Plagiarism Tools
For quite a long time, plagiarism checkers have worked in a predictable manner.
They scanned your text, looked for exact matches in a database, and if they spotted the same string of words elsewhere, they flagged it.
The traditional approach is very effective for blatant copy-pasted text, but it isn’t smart enough to catch paraphrased content.
AI plagiarism tools work differently. They don’t obsess over identical word sequences.
Natural language processing (NLP) and machine learning technology tells when a sentence has been paraphrased or “lightly disguised.”
Also, old-school tools usually compare your text against limited academic archives or a handful of websites. AI, however, pulls from a far wider compilation of sources, so its coverage is naturally broader.
Key Features of Our AI Plagiarism Checker
Now, what really makes the Undetectable’s AI plagiarism checker free and so trustworthy is that over 20 million people already use it.
Here are some of the reasons:
- It’s free to use, really! You don’t need to buy a $50 subscription to check your work, just paste it, hit “Check AI Plagiarism,” and you’ll see results instantly.
- It exactly pinpoints if any AI generation tool was used to write your text. So, in case your text matches with how AI models like ChatGPT-4, Claude, or Gemini write, it’ll get flagged.
- It has an award-winning accuracy with independent test scores at 85–95%. Recent updates have pushed this accuracy to 97–99.6%, so, it’s clearly the sharpest AI detectors around.
- If your work does get flagged as AI-generated, Undetectable’s free AI plagiarism checker doesn’t just shame you and leave you hanging. You can run it through the built-in AI Humanizer and get your content re-written so it reads naturally and dodges AI detection.
How to Use Our AI Plagiarism Checker
It’s very simple to check for plagiarism with Undetectable’s AI Plagiarism Detector.
Just go to Undetectable AI Plagiarism Checker, you’ll see a big text box in the center of the page with the words “waiting for your input” at its bottom left corner.
Copy the content you want to test and paste it into the box.
Or, if you’re just curious to test-drive the tool, click the “Paste AI Text Sample” button instead to get a sample passage so you can see how results are displayed.
Once your text is in place, hit the black “Check AI Plagiarism” button in the bottom right.
At this point, sit back for a few seconds as the tool scans your text to check for similarity across millions of sources on the internet.
The output is split into two parts.
At the top, you’ll see the overall likelihood that your text was written by AI. Below, the tool runs your text through multiple detectors such as GPTZero, QuillBot, Copyleaks, Grammarly, and others.
The AI detection feature so far is completely free.
You can run as many checks as you want without signing up or reaching for your credit card.
If your text does, however, get flagged, you have two choices.
- Use the built-in Undetectable AI Humanizer, which will rewrite AI-style phrasing into a more natural one. That does require you to sign up, but it can save you time if you’re in a hurry.
- Manually edit your text, which costs nothing except a bit of effort. You’ll have to add details only a human would know, mix up your sentence lengths, and drop in specific examples and data points to make the text AI-free.
Once you’ve revised, paste the text back into the checker and run it again until you get a safe percentage, ideally, less than 10% AI.
And just like that, you’re done.
Benefits of Using the AI Plagiarism Checker
We live in a time when ChatGPT can draft a piece of content even faster than the time you’d take to brainstorm it.
It’s convenient, sure, but there’s no guarantee that it actually connects with the reader.
For students and educators
Professors at any educational institute have radar for anything that sounds too formal.
It’s not their fault, as well. Schools and universities have to maintain a certain academic integrity when AI tools are only a click away.
If you’re a student, running your assignments through an AI plagiarism checker before submitting them will help you avoid getting flagged for unintentional AI use.
It protects you from unnecessary drama and academic penalties.
The AI plagiarism tool is a kind of detection system for professors to ensure that the submissions they receive are genuinely student-produced.
It allows teachers to confidently grade assignments without Googling suspicious sentences in every submission.
In other words, it helps institutions set clear boundaries where creativity and originality are welcome, but shortcuts masquerading as effort are not.
For businesses
Content for businesses is their sole branding and visibility driver.
If your marketing materials are stuffed with AI-written paragraphs, you could risk copyright infringement issues. Or worse, credibility issues.
Also, search engines are increasingly fussy about AI-generated content.
Google explicitly says that creating AI content when the main goal is to manipulate search rankings goes against its spam policies.
Customers also value the authenticity that comes with human-written content.
The Ipsos Consumer Tracker found that most people still favor human-created content over AI.
Roughly 75% of Americans prefer humans behind news and entertainment, and about two-thirds want marketing materials to come from people.
Using an AI plagiarism checker ensures that what you publish is not only safe but also trust-building.
Best Practices for Using AI Plagiarism Checker
Like any tool, an AI plagiarism tool works best when you know how to use it.
To get the most out of your checks, here are some smart practices to follow.
- Run your content through the checker as soon as you finish drafting. Don’t wait until ten minutes before the deadline to paste your 3,000-word essay into the tool, because if your results come back waiving a red flag, you won’t have sufficient time to fix them.
- The built-in “Humanizer” is great when you’re short on time, but it won’t magically make your text too brilliant. Always read through the output, personalize it, and inject some of your own voice.
- Just because a text passes the AI check doesn’t mean it’s automatically good to go. Run it through your own mental filter and check for grammar and punctuation before turning it in.
- Add lived experiences and insights tied to your actual expertise in your text. The more specific your work, the harder it is for AI to mimic it, and the less you’ll need to “humanize” later.
