What is Plagiarism?

What is Plagiarism?

Plagiarism involves using someone else’s work without giving appropriate credit, essentially passing it off as your own. It is a serious offense in academia and in many professional fields. There are various ways to commit plagiarism, including copy-pasting, paraphrasing without citation, and presenting others’ ideas as yours.

This is a big problem in the world of writing. When you take other people’s work without attributing it, they do not get credit for their hard work. This doesn’t feel good, and it breaks the rules about being honest at school or at your job.

Common instances of plagiarism

As mentioned earlier, plagiarism comes in many forms. To be aware, here are some common types:

  1. Complete plagiarism: This is the most obvious type. It’s when a writer passes someone else’s work as their own.
  2. Direct plagiarism: It’s also called verbatim plagiarism. This happens when an author copies word for word from another source and does not give credit where it’s due.
  3. Paraphrasing plagiarism: Here, one spins the words or ideas of someone else without providing a proper citation.
  4. Self-plagiarism: You might think this isn’t possible, but it is. It’s when a writer uses their past work again in a new piece without stating that it has been used before.
  5. Patchwork plagiarism: This type involves copying different parts from various sources and mixing them together as if they’re original.
  6. Accidental plagiarism: Even with good intent, plagiarism can happen by mistake if one forgets to cite their sources correctly.
  7. Mosaic plagiarism: A little harder to spot, this involves using phrases from different sources and sticking them together without citation.

The impact of plagiarism

Plagiarism hurts those who do it. It shows a lack of originality and honesty. The act of plagiarism can cause big problems for bloggers. If you copy others’ work, your readers will lose trust in you. Also, the person whose work was copied may take legal action against you.

A heavy price is often paid by those caught plagiarizing. Schools might fail students who copy others’ work. Job seekers could lose job offers due to dishonesty in their applications or resumes.

In both cases, your reputation takes a hit that’s hard to recover from.

“It’s impossible to say enough bad things about copied material. In addition to the instant risk of legal trouble, it is a major threat to the trust that companies work hard to build with their partners, customers, and even other companies in the same industry. In this digitally connected world where data is stored and shared easily, any kind of plagiarism can quickly hurt a business’s image.” Jason Wise, Editor, EarthWeb

How to Choose the Best Plagiarism Checker

How to Choose the Best Plagiarism Checker

When choosing a plagiarism detection tool, key factors such as accuracy, usability, cost, additional features, and customer reviews play a significant role.

Dive into the full comparison to find the best online plagiarism checker tool that suits your needs.


The accuracy of a plagiarism checker tool holds great value. It determines how well the software can detect plagiarism in your piece. You must trust your tools to catch all types of plagiarism. No one wants to face problems with missed spots or false positives. Every accurate plagiarism checker tool scans deep and wide.

This means it checks many pieces of work on the web as well as books. A poorly spotted check could bring low scores, bad reviews, or worse. So, making sure your tool has a high level of accuracy is key to a job well done.

However, keep in mind that even the best plagiarism checker software might not be accurate at all times. No amount of plagiarism is acceptable, but in various fields, certain score ranges are. For example, a plagiarism percentage of 30% is considered fine for blog writing and 15% or below for SEO blogs. Publishers of manuscripts usually allow no more than 5%–7% similarity. For students, the acceptable plagiarism score varies, as it generally should be less than 15%.

“Trying to prevent plagiarism is an ongoing battle due to the advances of AI, the sheer amount of content available on any given topic, and the ease with which people can copy content from the internet and claim it as their own. Fortunately, tools like Grammarly can help spot plagiarism in a few seconds by analyzing millions of web pages, so plagiarized content can be rejected before it is published.” Nathan Turner, Content Writer, Internxt


Usability matters when choosing a plagiarism checker tool. Great tools should be user-friendly and simple to navigate. You don’t want to waste time figuring out how to use it. An easy-to-use tool will help you find text similarity quickly.

The quality of support can also make or break your experience with a tool. It’s smart to pick a checker that offers good customer support when you need it. This way, issues get solved quicker. The easier the tool is to use, the more time you save in writing blogs or academic papers.


Paying for a plagiarism checker tool is part of your blog costs. Not all tools have the same price. Some are cheap, while others can be costly.

There are big differences in cost among these tools. Scribbr’s service ranges from about $19.95 to $39.95, depending on how long your document is. You must also think of how much value you get for what you pay: accuracy, ease of use, and extra uses like grammar checks or a citation generator should weigh into your final choice.

Additional features

Extra tools make it easy to find copied work. These can be links that show where the exact words are used online. Some checkers have tools that highlight parts of your text that match other places on the web.

You might want a checker tool that checks different types of files, too. The tool should allow users to upload different file formats, such as PDFs, Word documents, and more. Check if the tool supports these formats before picking one.

The tool should provide you with a detailed online report as well. It’s important to review it and not just rely on the overall score, as plagiarism checkers work by detecting similarities, not plagiarism, and not all similarities are plagiarism.

Customer reviews

People often talk about their experiences with a plagiarism checker online. These are called customer reviews. They can help you learn more about the tool’s features, accuracy, and how easy it is to use.

Users also share their level of satisfaction with the support they got from the service provider. So, be sure to check out these reviews before choosing a tool.
