Ever hit “submit” on a research paper or freelance writing assignment and wondered… What if this gets flagged as plagiarism?
Even if you haven’t plagiarized anything intentionally, it’s still normal to feel that tiny rush of panic.
That’s why plagiarism checkers exist. But the thing is, not all plagiarism checkers are 100% accurate or thorough.
One popular tool is EssayPro’s Plagiarism Checker.
While EssayPro is best known as an essay writing service, its Plagiarism Checker is a bonus AI tool designed to help writers quickly check for potential plagiarism before submitting their work.
But how well does this tool really work? And is it worth using over more established plagiarism detectors?
In this EssayPro review, we’re finding out by putting the tool to the test.
TL: DR – EssayPro’s Plagiarism Checker is a secondary feature of its essay writing service.
While the tool can reliably detect fully plagiarized content, it does not offer deeper plagiarism insights like more traditional plagiarism detectors.
Key Takeaways
- EssayPro’s Plagiarism Checker is free and quick, but only detects direct copy/paste plagiarism from online sources.
- The tool lacks AI humanizing features, advanced plagiarism insights, and solutions to fix flagged content.
- EssayPro is limited compared to dedicated platforms like Turnitin and Undetectable AI.
- Undetectable AI offers both AI detection and humanization, allowing users to refine flagged content for originality and human-like readability.
What Is the EssayPro Plagiarism Checker?
The EssayPro plagiarism checker is a free online tool offered alongside the platform’s professional essay-writing services.
On the surface, EssayPro’s plagiarism checker looks appealing if you want a quick (and free!) way to check for plagiarism before turning in an assignment.
However, unlike dedicated academic plagiarism platforms (like Turnitin), EssayPro can’t provide you with detailed insights on sources, similarity percentages, or actionable feedback to help you fix flagged sections.
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.
In other words, it’s a basic plagiarism tool tacked on to an essay writing service.
Which is helpful for quick checks, but it’s not really enough for students, academics, and professional writers who need an accurate and detailed plagiarism report.
How EssayPro Plagiarism Checker Works
Using EssayPro’s Plagiarism Checker is relatively straightforward.
Here’s what the process looks like:
- Upload or paste your text: You can either copy and paste your essay into the text box or upload a file directly.
- Run the scan: The tool checks your text against a database of online sources to detect duplicate or highly similar content.
- Receive a similarity report: Your results appear within seconds, showing whether any sections of your work match published sources. You’ll see a percentage of originality and highlighted areas that may need to be rewritten.
Key Features of EssayPro’s Plagiarism Checker
Although very basic, EssayPro’s Plagiarism Checker does come with a handful of key features.
Here’s what you can expect:
- Free access: Unlike other plagiarism detectors, EssayPro’s tool is completely free to use without signing up. And, you can check up to 3,000 words, which is definitely a plus given many other tools are capped at lower wordcounts (at least for the free version).
- Supports both text and file uploads: You can either paste your text directly into the text box, or you can upload a document that the tool can scan and analyze for you.
- Basic similarity detection: The tool “finds text matches in public sources” to flag copy/pasted and near identical matches.
- Simple user interface: This tool is clean and straightforward. No sign-in or payment required, which is perfect if you’re just looking to run a quick check.
Overall, EssayPro’s Plagiarism Checker is a decent entry-level tool if you just need a fast, no-frills scan.
Performance Analysis: Accuracy & Limitations
Now, let’s dig a bit deeper to answer that burning question: Is EssayPro reliable?
To test this tool, we tested two writing samples taken from the Undetectable AI blog.
Here’s what EssayPro’s Plagiarism Checker found.
For the first sample, we took a snippet from our own blog What Is Predictive SEO and How Does It Work?
Sample #1 EssayPro result: 100% plagiarized
So far so good!
We then tested another sample to make sure the tool worked again. For the second sample, we took a snippet from Who Owns AI-Generated Content in 2025?.
Sample #2 EssayPro result: 100% plagiarized
Great! So far, EssayPro is reliable at detecting word-for-word plagiarized content. But is that enough for real-world writing tasks?
Limitations of EssayPro
While EssayPro’s plagiarism checker does exactly what it says it can do, it does come with a few limitations that can hold it back.
For example, the Plagiarism tool itself cannot detect if the content was AI-generated. For that, you have to use EssayPro’s AI Detector tool.
To test the accuracy of this tool, we created a piece of AI-written content with ChatGPT and put it to the test.
Here is our generated text:
We then checked this text with EssayPro’s AI Detector and our own Undetectable AI Detector.
Here’s what we found.
EssayPro result: Nearly 100% AI
Undetectable AI result: Nearly 100% AI
From this test, we learn that EssayPro can detect word-for-word plagiarism and AI.
However, unlike Undetectable AI, which offers the option to both detect and humanize the content, EssayPro offers no built-in solution for fixing any plagiarized content.
EssayPro does advertise that it has an AI humanizer tool, but it’s not available yet (and there’s no information available about when it will be released).
In contrast, Undetectable AI already has a proven AI detector and humanizer up and running, and it’s consistently rated among the most accurate detectors in independent rankings.
Pros & Cons of EssayPro Plagiarism Checker
Now that we’ve experimented a bit with EssayPro’s Plagiarism checker, here’s a breakdown of where the tool delivers and where it falls short.
| EssayPro Plagiarism Checker: Pros and Cons | |
| Pros | Cons |
| It’s free to use, no paywall or subscription needed. Gives fast results, can create reports in seconds. Simple interface, which makes it easy for first-time users to navigate. It’s reasonably accurate and works really well for obvious signs of copy/paste plagiarism. | No AI humanizer, which makes it difficult to rewrite or paraphrase flagged content. Limited accuracy, the tool struggles to detect more advanced forms of plagiarism. Basic reports, only showing percentages and highlighted text without detailed sources. Not an AI-first platform, the plagiarism checker feels like an add-on to its essay writing services, and not a specialized solution. |
Comparison With Competitors
EssayPro’s AI detector really starts to show its weaknesses when stacked against dedicated plagiarism and AI detection platforms.
Here’s how it compares.
EssayPro vs. Turnitin
Turnitin is still the gold standard for academic plagiarism checks, scanning billions of academic papers and proprietary databases. EssayPro only checks against online sources, so it’s not suitable for university-level submission checks, which can detect many different types of plagiarism.
EssayPro vs. Undetectable AI
Undetectable AI consistently ranks among the most reliable plagiarism and AI detectors, including recognition in ZDNet’s benchmark.
EssayPro’s tools, by comparison, are only an add-on to the platform’s core services and are not typically perceived as a leading AI support tool.
The other sticking point with EssayPro is that while it can identify plagiarized and AI-generated content, it offers no solutions (other than having one of their writers fix it for you).
With Undetectable AI’s Stealth Writer and AI Humanizer, you can make sure your writing passes AI detection tools and then fix any flagged passages of text yourself.

Is EssayPro Legit? Our Final Verdict
So is EssayPro a legit tool? Based on our tests, the answer is yes… but only to a point.
EssayPro’s Plagiarism Checker works great for detecting direct copy/paste plagiarism issues for free.
However, EssayPro isn’t an AI-first platform. Its plagiarism checker feels more like an add-on to advertise its essay-writing service, rather than a tool built for accuracy and depth.
It can’t catch all different types of plagiarism, it doesn’t integrate AI detection into the checker, and (most importantly), it offers no way to fix flagged content directly in the text box.
So yes, it’s “legit” for surface-level plagiarism checks, but it lacks the depth needed in academic and professional settings.
For a more advanced solution, use Undetectable AI’s Stealth Writer for unique, human-like content.
Pair it with the AI Humanizer to ensure your writing sounds naturally authentic and passes AI detection.
