The internet has made it unbelievably easy to do research about almost anything. With information right at your fingertips, you can devour several articles, short documentaries, and whitepapers in just a few hours. No wonder lots of people nowadays have become lax when it comes to citing their sources. Students in particular, don’t feel the need to list where they got certain lines or sentences.
But plagiarism is no joke. If you’re reading your work and you come across something that you feel you’ve read or heard somewhere, there’s no harm in quoting the original source. Whether you’re a student or a professional, it pays to cross-check your references.
Why Use a Plagiarism Checker?
There are all kinds of plagiarism: from copying someone else’s work and claiming it yours, to performing or playing copyrighted material without permission. Two of the most common examples are a) copying words and/or sentences without citing sources, and b) not putting direct statements in quotation marks.
One way to verify if it’s okay not to attribute the source is to check its usage permissions (as in the case of images, videos, and music). But your safest bet is to avoid committing plagiarism entirely.
However, proofreading your work can take a lot of time, especially if it’s a research paper or a long essay. The trick then is to use online tools, such as plagiarism checkers, to speed things up. Many plagiarism checkers today are free to use, and even come with enhancements to make your writing better. For instance, there are online tools that can check for grammar, spelling, as well as word suggestions based on context.
Plagiarism is a serious issue. If you don’t ensure your work is spotless, you can get a failing grade or probation. The worst-case scenario is, it can also lead to a legal battle. You don’t want that kind of headache.
So keep yourself away from trouble while still producing original masterpieces. Use these online plagiarism checkers to make your writing better!
