Why Should I Use a Plagiarism Checker? 

Copying written works without proper referencing is unacceptable in the academic realm. Moreover, plagiarism is an offense you can be charged with, imposed a fine, and even taken to jail. Most importantly, whoever gets caught risks ruining their reputation and even jeopardizing their career.

Hence, it’s vital to pay attention to the originality of your papers. Admittedly, “borrowing” works from other authors seems compelling and less time-consuming, but the consequences can be terrible. The fault would be yours, even if you do it unintentionally due to a lack of time or ignorance.

That’s where a free plagiarism checker online can be of immense help. These online tools are inexpensive (often free), convenient, fast, and reliable. Here are several reasons why everyone must consider a plagiarism checker to scan their essays:

  • The tool highlights the copied content and helps you navigate the plagiarized text.
  • These apps boast extensive resources in their databases for easier plagiarism detection.
  • They display percentages of copied and original text, with links to the websites featuring the plagiarized text.
  • Plagiarism tools are fast and straightforward to use.
  • The software offers suggestions to modify your text and make it authentic.
  • Some plagiarism software can spot unsuccessful attempts to paraphrase the content.


Quetext is an excellent plagiarism checker that detects most of the plagiarized content. However, it doesn’t perform to the highest standard for scholarly articles. Another thing is that individual source sentences get matched to several original texts, and you could get a false impression about the plagiarism level. As a result, you might obtain false positives.

Users can insert up to 500 words at once and run the free trial plagiarism checker. If you want to scan more extensive texts, you will have to select a package. The paid versions start at $10.49 a month.

At Quetext, you can download reports that pinpoint partial finds with orange and full matches with red. You can also get help with citations and spellcheck. As for trustworthiness, the app never stores nor reuses your papers and guarantees your privacy.


As one of the best plagiarism checkers on the market, PapersOwl is a free tool that conducts in-depth text analysis. It is 100% safe and never misuses your papers without your knowledge. Plus, you can insert files in various formats without word count limits.

PapersOwl’s tool catches even the slightest traces of plagiarized content and gives detailed explanations with percentages. It also features a title generator for essay for free. The checks run super-fast; it takes about 20 seconds to scan an average article of 2,000 words.

Finally, PapersOwl offers on-the-spot solutions for your writing problems. You can hire skilful writers displayed on the web page to rewrite, proofread, and edit your paper.


Grammarly is a first-class plagiarism checker that strives to deliver all-encompassing excellence. As your virtual assistant, Grammarly tracks your writing for linguistic accuracy, readability, and plagiarism. It is available as a browser extension, as an app, and as a word-processing tool plugin.

However, the free version lacks several helpful features. For instance, it won’t tell you which content is inauthentic but only the percentage of plagiarized work. Conversely, the paid tiers ($12 a month billed annually) check your spelling, grammar, punctuation, tone, clarity, and engagement. They also compare your papers with over 16 billion websites. It works directly in your document and alerts you of plagiarized sentences. The tool is safe since it doesn’t store and share your documents.
