Our anti-plagiarism engine comes with a reporting option which allows you to download a report of the plagiarism search you run. This means you now have some sort of evidence to send across to the relevant parties and a record to keep. Awesome!
How about an option for sharing the plagiarism report generated? Would you like that right INSIDE the tool, too? Well, we got you covered!
This feature allows you to check plagiarism on documents in other languages other than English. So whether your content is written in русский, 日本語, italiano, français, Português, Español, Deutsche, 中文, our tool can speak your language.
Live in the cloud? Our originality checker is able to check content from the cloud, including Google Drive and Dropbox. Simply choose where your content lives in the cloud and pick the particular piece of document you want to run, and our copyright checker will do the rest.
If your content is rather local, living in a file within your computer, then you can upload it directly from the local storage.
Once you've uploaded your content and clicked to check for plagiarism, our duplication checker will show you, in percentages, the levels of both plagiarized and unique content in the document. For example, it'll let you know that 82% of the content is unique while 18% is plagiarized.
The tool does not stop at showing you the percentage levels of plagiarized and unique content. It also shows you, in a list format for easy detection, both plagiarized (if any) and unique areas of the content piece, sentence-by-sentence. Plagiarized sentences are shown in red while the unique ones are shown in green for your convenience.
With just one click, you can also see the result in a document view, where the whole content is displayed in one document and the plagiarized materials are highlighted in red.
Right within the tool, you can view the external content that matches the red sentences in your document. Plus, the URL of the external webpage is added for a quick and easy examination of the content.
After the results are in, you can click on the "Compare" button on any red (plagiarized) line to go to Google and compare that particular content with similar ones already published on the web. Great for finding where the plagiarized content is coming from.
If you don't want to detect plagiarism for a specific URL? Simply Insert that URL in the Exclude URL box and that'll be done for you automatically, Copied (plagiarized) content from that URL won't be countered as plagiarism.
If you want to develop a real-time multitasking plagiarism detection system, incorporated into your website, then we have your back.

This completely eliminates the need to check each and every article for every student individually and saves you hours upon hours of work and headache.

This also works great for big websites who accept dozens of articles from contributors frequently.

You can also compare plagiarized content within the plugin by clicking on sentences.

Whether you know it or not, plagiarism does affect you in some way. It doesn't matter whether you're the content creator or the one who consumes the content, plagiarism affects us all.
As a content creator (writer, author, researcher, student, freelancer, blogger, social media manager, etc. It's no news that you should be regularly checking to be sure that nobody is copying your content without your permission or giving you credit.
But much more than that, you also have to always run your content on a plagiarism detection tool before publishing or submitting it to be sure that your work does not contain plagiarism.
Why? Because plagiarism is an act of academic dishonesty, a breach of journalistic ethics, and above all, a publishing crime.
As such, you don't want to fall victim. If your work contains plagiarized content, whether intentionally or by ignorance, you stand to face serious penalties including:
This is not to mention other consequences like SEO content duplication penalties and lowered rankings, lost trust, possible academic sanctions, and more.
