This plagiarism detector is mostly intended for students who want to make sure their essays, research papers, and other types of content are unique before the submission. The software compares your content to millions of academic works published on the Internet. When you fix the problematic parts, you can rest assured that your professors won't be able to detect any plagiarism in your papers.

What Is Plagiarism?

Here is the simplest explanation: plagiarism is unauthorized usage and publication of another author's content, ideas, and style. When you rely on such practices to compose your papers, your professors will consider the content to be plagiarized, and you'll get sanctioned for it.

Plagiarism can be intentional and accidental. When you deliberately use another author's ideas and content without giving credit, the plagiarism is clearly intentional. However, you can still end up with a plagiarized paper if you get a little too inspired by different sources during the research process. You read a lot of information about the topic you're elaborating, so you process it and accept it as your own knowledge. Soon, you forget where you found that information and you present it in the paper as your own. That's called accidental or inadvertent plagiarism.

How Can Your Teachers Identify Plagiarism?

That's simple: they use a plagiarism checker. Since most of them request the papers to be submitted in electronic format, it's easy for them to copy and paste the content into a free plagiarism checker, which identifies the parts that have been copied from online resources. This is how your teachers identify intentional plagiarism, so it's important for you to reference all sources you use.

Some students try to trick their teachers by paraphrasing online resources, but that's a practice that may backfire on you. Your professors have already read most studies and academic articles related to their niche. When they recognize ideas and arguments from other authors in your text, it will be easy for them to find the right source. Thus, your paper will still be marked with the tag plagiarized.

Academic integrity is extremely important for all schools and teachers. They want you to learn how to write proper academic papers with well-formatted references and unique arguments that define your point of view. Remember: it's okay to use plenty of resources when writing your essays and research papers. However, it's not okay for you to present those sources as your own ideas.

How to Avoid Plagiarism

There are few tactics that help you use online resources in a smart way.

  1. Reference the sources. Always!

  2. Referencing is boring, mainly because you have to follow a specific format for different types of resources. For example, you need to reference online resources in a certain pattern, and maintain a different format when you use books. You have to follow a certain citation standard for all references (Chicago, Harvard, MLA, APA, and Turabian are the most commonly used citation styles).

    You should always keep notes of the references you identify during the research process. Note where your ideas came from, and provide the references progressively, as you write the content.

  3. Learn the difference between quoting and paraphrasing

  4. When you use the exact words of another author, you put them in quotes. Paraphrasing, on the other hand, means that you're using another author's ideas and you're putting them in your own words. There is something that quoting and paraphrasing have in common: both need references.

    Most students make a mistake thinking they don't need to include references for the paraphrased parts, but they are wrong. Teachers can recognize those ideas, and even a plagiarism detector can identify the resources if you copy parts of the sentences.

  5. Always check your papers with a plagiarism detection engine

  6. No matter how careful you are during the research and writing process, you may still involve some unintentional plagiarism in the paper. That's why it's important to check the content through detector, just to make sure it's perfectly clean of any sign of plagiarism.

It's not that hard to write unique content when you set your creative and critical mind free. Use the resources only as inspiration to form your own arguments, and never forget to provide proper references!
