What plagiarism is

According to the Merriam-Webster online dictionary, to “plagiarize” means
1) to steal and pass off (the ideas or words of another) as one's own
2) to use (another's production) without crediting the source
3) to commit literary theft
4) to present as new and original an idea or product derived from an existing source.

Even though composing an essay or a blog post with the usage of a text written by an unknown writer found in the Internet might seem very innocent, it is not at all. Most developed countries, such as the U.S., Canada, the EU, Australia, have copyright laws that protect intellectual property. So, in theory, one might get punished quite severely for passing off someone's work as his own or, worse, for an attempt to get credit for something that does not belong to him (thoughts, words, ideas).

Plagiarism prevention and detection

Academic plagiarism detection is one of the most significant problems in today’s education. Vast availability of Internet resources made it extremely easy for students to copy/paste materials without giving any credits to real authors. All schools, colleges, universities apply very harsh measures for those students caught with plagiarism -- it either can be a failing grade or a complete discharge from the institution. The only way for students to avoid plagiarism is to properly cite the sources, acknowledging and referring to the author of an original text. And the only way for teachers to prevent their students from plagiarizing from online sources is to use an accurate plagiarism checker.

Plagiarism checker, how does it work?

Our service offers an innovative and user-friendly online tool that helps students and teachers to detect and prevent academic plagiarism. The sophisticated, yet easy-to-use plagiarism checker conducts thorough and in-detail scan for plagiarism. A scan of any documents takes a few minutes only. As a result, the program highlights the plagiarized parts of the text, indicates the original source the passage was initially taken from, and provides overall percentage of the plagiarized material. Finally, generates a full report, indicating the overall originality rating and the percentage of plagiarized materials in the submitted text. You can share plagiarism reports with other people by simply giving them the link of a report, generated by our program. Our program supports all major European languages. It means that you can check for plagiarism documents in English, French, German, Italian, Spanish, Portuguese, etc.

We protect your privacy and intellectual property

Our plagiarism detection software is designed to leave no chances for plagiarized works and runs against all the available Internet resources, including websites, digital online databases and online libraries. Having said that, we do not have our own databases and promise not to store any documents uploaded for plagiarism scan. We feel very strongly against using our customers' files for our own benefit, which is filling a database that can be further used for commercial purposes.

FREE plagiarism checkers? There is no free lunch out there, really

If you upload your file for a free plagiarism check, be sure it will be added to a database and later either sold online or used in another way without your consent. A penny that you are trying to save on a plagiarism detector might cost you a dollar in the future.

How does the plagiarism report look like?

Our report is extremely user-friendly and easy to understand. It can be viewed in your reserved personal area or downloaded in pdf format. It will show you the document’s overall plagiarism rating in percent and the plagiarized parts of text with links to the original document (they appear in different colors, depending on the intensity of plagiarism). No free plagiarism checker will offer same accuracy.

Do you check against your own database?

NO! Being a company that promotes such values as intellectual rights and agreed usage, we feel very strongly against databases of documents that do not belong to us. Any file that is stored on our server is only accessible to the person who uploaded it for the period of one month. After that time, we will perform a scheduled clean-up and a file will be deleted. Customers can download their ready plagiarism reports in pdf format.

What is “check on background”?

Once you have an account with us, you can instantly submit multiple documents to check for plagiarism. There is no need to wait for the program to check your text.

You can see the progress for each report in real time – the page is interactive. You can leave the page and return back later to examine or download your ready plagiarism detection reports.

What is my account balance?

We offer two types of accounts. Our personal account gives you the access to check 15,000 words for plagiarism. It is about full 80 pages of text. Usually, it is enough for the entire semester (5-6 months) to check written works for all classes for an average student. It is also a perfect solution for bloggers who can check up to 100 of their blog entries. Our organization account gives the access to scan 100,000 words within one master account, including all sub-accounts and groups. Each time a search for plagiarism is performed, the account balance is being debited for the amount of words the document contained. Account balance can be refilled at any moment, keeping your previous account history and settings.

What if none of your offered accounts suits my needs?

In this case, we invite you to contact us stating what you are looking for and we will formulate a personalized package especially for you. We are ready to customize account features and pricing based on individual requests. For example, for schools with large amount of students, we can create a package with hundreds of manageable sub-accounts, with individual access for each student or instructor.

For organizations

Plagiarism checker perfect for teachers

There is an old joke: 70% of students admitted to have plagiarized at least once during their studies, while the other 30% just lied about it. Unfortunately, ever since the Internet has entered our lives and became available to anyone, many people started using the information they find there in the wrong ways. It does not take much to search for relevant materials, copy them and present them as your own. Teachers, being aware of this huge problem, try to protect the value of real education by using plagiarism checkers, whose importance is difficult to overestimate these days. There are several reasons behind the growing popularity of plagiarism checkers – they are used for different motives, obviously, and the positive results outweigh the possible drawbacks by far.

While many students perceive the usage of plagiarism checkers as a punitive measure, teachers explain they see it in a different way. Teachers use plagiarism checkers not necessarily because they want to find out whether their students plagiarize and if they do, they need to be severely punished for it. Plagiarism checkers are used mostly because teachers want to prevent plagiarism. It is their way of explaining that plagiarism is bad, that students need to study on their own, do their work themselves and that they will be evaluated based on how well they accomplish their tasks. Most teachers do not like to see their students expelled from school or college. Most teachers teach because they like what they do and there is no greater pleasure for them than to see their students become successful. In a similar way, many students go to school or a university because they want to study, become smart an professional. Even if some of them at times are too busy or demotivated, in fear of being caught and having big troubles, they actually prefer to sit down, do the research and writer their own essay or research paper.

Even though most schools have already set strict rules as to plagiarism, it is probably best to deal with each proven case with a personal approach, taking into consideration the outcome, the motives, the degree of plagiarism. Those students who just wanted to get a good grade, at the same time avoiding hard work and could not be bothered to sit down and write their own paper, should be punished and everyone else should be made aware of this case and punishment. Other cases, when somebody unintentionally paraphrased the information he/she read or heard about, should be treated differently. Students need to be warned about the possible consequences of plagiarism in their written works and informed on how to protect themselves from any unwanted problems.

So why is plagiarism so dangerous and why responsible teachers are so keen on fighting it?

First of all, when a student plagiarizes, it completely stops his learning and thinking process, it just puts a certain block in our brains. There is just no need to analyze, criticize, evaluate. All you need to do is find relevant information and copy it without even reading much through it. Secondly, if one takes plagiarism as a habit, it makes it absolutely impossible for him to get any education at all. One can certainly get away with all the copying and pasting, graduate and get even “a degree”, but would it all be worth anything? Surely not, it will only be a useless piece of paper. Nobody can become an engineer, a lawyer or a teacher without actually studying, reading and researching. It can be quite scary to imagine that a certain percentage of these “professionals” have earned their degrees that way. Thirdly, any kind of cheating is very likely to reflect in other areas of a person's life.

Many teachers say that they almost always know whether a piece of writing is original or not. Writing style is as unique and original as handwriting is. A teacher with experience has read so many students' works that it does not take much effort to recognize when one piece of someone's writing is different from another piece done previously by that same person. If the writing is way too good, or too complex, or too knowledgeable – it most probably has been plagiarized. In many cases, teachers even find something like the ideas from last year's student's works, or even whole pieces copies paragraph by paragraph. In other cases, it is needed to use a plagiarism checker to determine whether a document is original and if not, see the sources it was copied from.

Teachers hate to admit, but these days the work load at schools, colleges and universities is so heavy that most students are almost forced to seek for an outside “help” to get everything done by the deadline. Even the brightest and the most motivated guys just cannot cope with various assignments they get each day. This is especially true for those students, who do extracurricular activities, such as sports, or who simply are involved socially. Working students usually barely manage to attend classes, left alone completing homework and projects.

While schools and colleges mostly use plagiarism checkers to define plagiarism in the already turned in papers, many teachers encourage students to run checks before submitting a paper. According to them, cases of self-plagiarism or unintentional plagiarism are not rare as well. It is too easy to repeat word-by-word some piece of information you already know or you have previously said/written. Because good education does not have punishment as its goal, responsible institutions try to make sure their students' works are protected and their reputation is spotless. Moreover, by using plagiarism checkers, students adopt the culture of unacceptableness of plagiarism, respect of intellectual property and intellectual rights. This will surely contribute greatly to creating a healthier education environment.
