We are piloting it for the School of ICT, IBTE. We've chosen the modules and appropriate assignments/assessment which involve course work to apply PlagiarismCheck.org software. Our instructors and students find it very handy to use this. Our staff is using it before submitting any important document or paper.
So far, we found no difficulty in using this user-friendly software. All of us were extremely comfortable with the software as it served what it supposed to be - checking for plagiarism.
The plagiarism checker enabled us to minimize the academic dishonesty. Previously, students would just ‘copy and paste’ from anywhere, they seldom cite and provide proper references in their assignments. We are hoping, and noticeable immediately, that after using the plagiarism checker, that the students are now much more aware of these issues and hence, academic dishonesty could be avoided, if not totally.
We started using PlagiarismCheck.org. The girls have found it easy to use. I enjoy the fact that teachers can create folders and pupils can submit their work to the teachers folder. I had a pupil whose plagiarism percentage was too high. PlagiarismCheck.org enabled me to click on the highlighted plagiarized sentence and go straight to the site.
I highly recommend this software.
PlagiarismCheck.org is very time saving and easy to navigate tool due to user friendly account interface. At present we are using similarity detection for student’s thesis, as it is useful to protect illegal use of research work. The features we enjoy are: creating folders, searching for reports and authors, reviewing word count and member details.
Faculty members are confident with the quality output of their research article now. The output format is really appreciable.

How a similarity checker can help teachers

A simple website that checks for plagiarism like ours can be a lifesaver for educators. Anyone can use it, and it doesn't matter whether you're teaching high schoolers or Ph.D. students. Here are some benefits our plagiarism checker offers.

  • A similarity checker saves you a ton of time. You don't need to run each paragraph of every single essay through a search engine. Instead, you can upload multiple documents to the plagiarism checker and analyze them in one click. It's an effortless way to automate the assessment process.
  • We offer an extensive and customizable database of texts. Our system includes a great variety of sources, some of which can't be openly accessed online unless you buy them. And if you want to analyze your files against some specific texts that aren't in our system, you can upload them and run checks with no problem. This way, you'll see whether your students are copying from one another.
  • Our detector shows the similarity percentage, so you don't need to conduct an extensive manual review to assess the originality of a single paper.
  • All the links to the sources can be found easily. We not only detect copied content but also determine where it was taken from. Check plagiarism and follow the hyperlinks if you need to review the original materials.
  • PlagiarismCheck can trace AI-generated content, including Chat GPT. With the solution we provide, you can ensure the text was written by a human and cultivate independent creative thinking and honest work.
  • Our product prevents ghostwriting. Thanks to Fingerprint, a unique function not provided by any other plagiarism checker service, you can verify the authorship and originality of a student's paper. The tool automatically compares the work to the student's previous writing style and checks for signs of writing by someone else.
  • PlagiarismCheck can be integrated with other educational platforms like Moodle, Google Classroom, and Canvas. We even have a Google Docs add-on!

Our plagiarism checker is a reliable assessment tool

If you're looking for legit, official software to help you check the uniqueness of documents, you've found the right site.

Our service operates online, so you don't need any authentication certificate to get it started.

It detects not only exact matches but also phrase rearrangements, words replaced with synonyms, as well as changes from active to passive voice and vice versa.

The plagiarism detector tool distinguishes between plagiarism and quotation, not marking references and citations as similarity by default.

On top of all this, it has a built-in citation generator and grammar checker to help you improve the quality of your papers.

Originality checker helps avoid all types of plagiarism

Basically, plagiarism occurs when one reuses any content from another source, such as a book or a website, and tries to pass it off as one's own without citing it properly.

If it is done intentionally, some use tricks to avoid verbatim copying - paraphrasing the text, adding hidden symbols, or using Cyrillic letters instead of similar Latin. Our plagiarism checker can indicate even the most intricate intentional plagiarism cases.

However, plagiarism can be occasional, when people just come to the same conclusions and express the idea in similar ways. Moreover, some students commit plagiarism by accident without any intent to cheat simply because they don't know that their sources need to be cited or how to cite them. Still, that doesn't exempt them from responsibility, so learning how to reference materials correctly is essential. The originality checker can highlight the problem and prompt correct citations according to standardized formats.

It's worth saying that one type of reference can often go uncited in creative writing.

It's called an allusion, and it's implicit but still obvious enough for the audience to recognize it from another work. Here's an example. T. S. Eliot alluded to another poet, George Meredith, by repeating his line in the context of his poem Cousin Nancy: “The army of unalterable law.” Eliot expected his readers to recognize and attribute the line to its original author. He used it intentionally without trying to claim it as his own. In fact, poets love making allusions because they add intertextuality to their creations, making them seem more profound. In this case, the reference is not considered plagiarism but is often accompanied by a footnote.

Plagiarism can come with serious consequences

Reusing other people's work may seem like an easy way out of writer's block, but it's not worth it. It doesn't matter whether you're working on a short English essay, a dissertation, or any other document. Usually, plagiarism is not considered a criminal offense, but it's still a severe violation of academic integrity and journalistic ethics. Being accused of it is a serious blow to any writer's career. Moreover, things might get really bad if you're caught in a copyright infringement suit. Then, it will be considered a crime. Luckily, using our reliable document plagiarism checker to scan each file can help you avoid this.

How to avoid copying in writing before you check paper for plagiarism

Here are some tips to help you write a text that will be proven flawless once you check paper for originality.

  1. Never copy and paste text from other sources. If you really need to do it, you better use quotation marks. However, refrain from quoting long paragraphs because they can ruin the flow of your writing. Limit yourself to no more than three sentences that best represent the idea you want to reference.
  2. Paraphrase and summarize the ideas you want to use. But remember, you still need to cite the source you got the information from, even if you're changing the text.
  3. Remember, you can't write a whole paper by simply rewriting other people's works. It would be considered plagiarism. You need to get creative and come up with your own material. Do some research on the topic to get yourself inspired.
  4. Develop your own style. Every person has a unique manner of expressing their thoughts in writing, and you're not an exception. You just have to find your voice.
  5. Understand what type of paper you're working on. If it's a literature review, the text is obviously going to contain many references. However, if it's a creative writing assignment, this is probably not the right time to use a lot of citations.
  6. Check paper for plagiarism before submitting the assignment to confirm that it is original.
