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 tool is carefully designed to help you easily and quickly detect plagiarism in any digital text-based content.
If you want to develop a real-time multitasking plagiarism detection system, incorporated into your website, then we have your back. The Plagiarism Checker API offers you a great API integration solution. 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. You can check plagiarism for multiple essays, thesis or assignments of your students in just one click. This also works great for big websites who accept dozens of articles from contributors frequently.
1. Billions of web pages.
If your content is rather local, living in a file within your computer, then you can upload it directly from the local storage.
And that is why we created the Plagiarism Checker by Small SEO Tools .
Now, on the other end of the spectrum, as a content consumer or user (reader, professor or teacher who vets students’ work, client of freelance writers, etc.), it is equally important to check for plagiarism before accepting or taking action on any content you come across or submitted to you.
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.
15. Exclude Specific URL.
Yet, we decided to make it 100% free.
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.
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.
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.
Sure enough, it can detect most of the plagiarized text in your document. But there are times when it fails to catch a single sentence or phrase.
Viper took a page out of Copyscape’s book and uses a flexible credit-based system in its pricing.
Unlike Turnitin and PlagiarismCheck.org, Viper isn’t heavily advertised as a tool for academics. They also have plans designed for bloggers, businesses, and websites in need of a plagiarism checker.
The plagiarism checker is available for WhiteSmoke users as part of their essential package. This costs $5 a month for an unlimited number of articles.
Thanks to WhiteSmoke’s affordable pricing, it can be everyone’s go-to proofreading and anti-plagiarism tool.
It doesn’t matter if you’re a student, teacher, blogger, or freelance writer. Producing 100% original written content should be your top priority.
To view the text sources, you’ll need to switch to the “Matched Sources” view. This lists down all the detected sources of plagiarized text and displays the similarity percentage.
Although Grammarly’s core proofreading features can be used for free, the plagiarism checker requires a premium account.
For plagiarism checkers, having several options when it comes to uploading files is always a plus.
You then have the option to add the documents to a project or just run a one-time analysis.
After the analysis, Plagiarisma loads up a compact list of plagiarized text and sources.
The SmallSEOTools plagiarism checker can be used free of charge for as many times as you need.
Let’s jump into it.
There you have it — the top free and paid plagiarism checkers on the web.
Who is it for?
If you’re a student, administrator, instructor, or an IT specialist in an educational institution, you can’t go wrong with Turnitin.
Citation can protect you against allegations of plagiarism if you follow the proper procedures.
The “ Business ” plan supports the creation of up to 100 user accounts — more than enough for the average content team. Professional writers, on the other hand, may settle for the “ Premium ” plan to meet their daily needs.
That’s why the Scribbr plagiarism checker deserves one of the top three spots on this list. Its database includes not only 60 billion web pages, but also millions of publications in various formats.
Remember how DupliChecker is loaded with truckloads of features for content marketers and bloggers?
If you’re familiar with Grammarly, that’s because it’s been featured in my blog several times. It’s primarily a grammar checker tool that automatically detects spelling, grammatical, and readability issues as well as provides corrections.
While Grammarly has what it takes to be a top plagiarism checker, I recommend purchasing it for its proofreading features.
The Copyscape free plagiarism checker is great for anyone who publishes content online.
You also have the option to enable the “DeepSearch” feature before you initialize a plagiarism check. The toggle will only be visible once you paste your text or upload a document.
When completed, the “Alerts” section of the Grammarly editor will show the results of the plagiarism check. This includes the percentage of plagiarized text in your draft and the sections in question.
Suppose you’re writing about a technical topic that involves terms you don’t fully understand.
For individual users, the monthly cost of a premium subscription is $29.95. This can be reduced to $11.66 per month if you plan to use annual billing.
The ability to check the originality of documents in your Dropbox or Google Drive account is a nice touch. But then again, it’s not exactly a game-changing feature.
