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.

Why you should use our anti-plagiarism software

Every experienced writer understands the importance of originality. In order to produce an excellent work, you need to make sure it’s new and novel rather than an imitation or a reproduction of someone else’s material. That’s when our plagiarism checker software can come in handy. Let’s go through some reasons why you should start using it.

The first one is pretty evident. If you’re a student writing academic papers, especially important ones like a thesis, you need to make sure they are authentic before submitting them. Otherwise, they won’t be accepted, and you’ll fail the assignment. If you’re a professional writer, you also want to make sure your article, novel, or whatever you’re working on is original, so that you won’t be accused of copying from other people. A plagiarism analyzer can detect significant similarities between your work and millions of others, highlighting the parts that you need to edit.

This tool is also incredibly helpful for effective paraphrasing. If you want to reference another source in your own words instead of just quoting it, it’s not enough to replace some words with synonyms. Run your text through a plagscan and see how close it is to the source. You should aim for a low similarity index.

Sometimes, writers may unknowingly repeat other authors’ ideas in their own writing. And despite the fact that they’re not deliberately stealing them, this is still considered plagiarism. So even if you’ve written your paper from scratch and are 100% certain that it’s completely original, it’s still better to be safe than sorry. Run it through an anti-plagiarism program just to be sure.

How an anti-plagiarism checker can help teachers

A simple online app like ours can be a lifesaver for educators. Anyone can use it, and it doesn’t matter whether you’re teaching high schoolers or PhD students. Here are some benefits our plagiarism checker offers.

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 plagiarism scanner 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. This program produces a very low percentage of false results and does not recognize references, bibliographies, title pages, and other bits of formatting as plagiarism. On top of all this, it has a built-in citation generator and grammar checker to help you improve the quality of your papers.

Different types of plagiarism

In order to avoid committing plagiarism in the future, you need to clearly understand what it is. Basically, plagiarism occurs when you reuse any content from another source, such as a book or a website, and try to pass it off as your own without citing it properly. Plagiarism can be intentional or accidental, verbatim or paraphrased, complete or partial. Whatever the case is, you must avoid it at all costs.

Many 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 it’s important to learn how to reference materials correctly.

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 a line of his in the context of his own poem Cousin Nancy: “The army of unalterable law.” Eliot expected his readers to recognize the line and attribute it 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.

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, plagiat is not considered a criminal offense, but it’s still a serious 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 all this.

How to avoid plagiarism in your writing

It’s actually very easy to write original papers. Here are some tips to help you:

  1. Never copy and paste text from other sources. If you really need to do it, 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 plagiarized. 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. Use a plagiarism checker with percentage before you submit your papers to confirm that they are indeed original.
