If you’re publishing content on your site and hiring other writers to do the heavy lifting, then you run the risk of getting content copied from other sources.

Unicheck
Unicheck is proud of its ability to help 1 million people from over 90 countries around the world.
They’ve checked over 120 million files in the process, and with a similarity report taking as little as four seconds, it’s little surprise they’re one of the top solutions for individuals, corporations, and colleges.
One of their main advantages is a set of distinguishing characteristics.
These features include a Google Docs add-on that detects plagiarism while you’re writing.
This implies that while you type into the Google Docs document, Unicheck will indicate citations and similarities at the same time.
This, in the end, saves you more time than you anticipated.
Aside from Google Docs, Unicheck also provides Google Workspace and Microsoft 365 Add-Ons for your convenience.

My favorite piece of plagiarism software is Unicheck.
I’ve tried several others (Grammarly, PlagScan, Scribr) and have found Unicheck to be the best.
It’s incredibly fast and searches a huge database.
It also integrates with several common apps, eliminating the step of having to convert to a specific file type
Scribbr
Scribbr is one of the most popular plagiarism checkers among students.
Its precision is designed to detect any type of plagiarism in your work by comparing it to their extensive source database.
The Own Sources Checker is one of their most notable features, allowing you to effortlessly check for self or auto plagiarism.
Although there is a price for this add-on tool, it is a huge help, especially for students who are publishing a manuscript but don’t have time to double-check it.
Detailed plagiarism reports with an accurate proportion of plagiarism, a list of sources that matched, access to settings to personalize your report, and a guide to help you improve your content.
Scribbr safeguards your privacy not just by encrypting their server cloud, but also by not storing your works in any database.
Scribbr is also known for its powerful plagiarism detection software, which provides more accurate findings each time you run a plagiarism check.
Grammarly
Grammarly is writing assistance that you’ve probably heard of.
When you have its extension installed on your Google Chrome browser, it detects grammar faults as you type.
However, not everyone has access to Grammarly’s high-quality plagiarism checker.
It not only checks for errors in grammar and tone (a new feature), but it also double-checks your work against over 16 billion online pages and ProQuest databases.
This free service ensures that plagiarism checks are correct every time.
Grammarly’s social integrations have grown in strength, allowing you to scan your work while writing emails, conversations, papers, and even posts on Gmail, Yahoo, Slack, Google Docs, Jira, LinkedIn, Twitter, and Facebook.
As a result, Grammarly provides feedback on the grammar structure of your work after each plagiarism check.
One of the reasons consumers favor Grammarly for plagiarism detection is its ease of use.
Grammarly will tell you whether you have copied or unoriginal content as soon as you hit scan after pasting your content, and paying for Premium will also give you access to the resources you need to correctly reference and credit your sources, avoiding plagiarism completely.
~
I’ve tested several plagiarism checkers over the years, and in my experience, Grammarly is the best package deal.
The plagiarism checker feature is integrated within the Grammarly editor.
With a single click, the tool will scan billions of websites and will provide you with a detailed report within seconds.
This includes the percentage of matching text, reference data, and link to the potentially plagiarized source.
Grammarly’s plagiarism checker is also one of the most accurate tools I’ve ever tested.
My other recommendations would be DupliChecker, Copyscape, and Scribbr.
PlagScan
PlagScan is well-known for its plagiarism detection, which it has done effectively since 2009.
It allows you to either copy and paste your content or upload a file to begin the plagiarism detection process.
Each scan for plagiarism is as exact as you need it to be, thanks to Yahoo’s BoSS-API.
Depending on your needs, you can choose from a variety of plan options to begin scanning.
Plagramme
Plagramme has a plagiarism checker that works in real-time.
The process starts with the detection of several sorts of plagiarism, such as copy and paste, illegitimate sources, mosaic plagiarism, auto plagiarism, and so on.
Following the creation of a report, you will be given a similarity score, which will show you the number of similarities found in your work.
Any detected plagiarism or similarity is noted so you can go ahead and correct it.
Plagramme is popular among kids and educators since it is straightforward and easy to use.
Plagramme’s free software version has no word limit, so you may check for plagiarism across all of your writing.
Plagramme is extremely useful in detecting plagiarism for writers, authors, entrepreneurs, students, and educators.
The assessment provides you with a percentage point that indicates how much of your content is original and how much is not.
Plagramme additionally provides an advanced plagiarism checker for research papers and thesis writers’ convenience.
Plagiarisma
Plagiarisma is my favorite plagiarism checker. The tool is easy to use.
Just copy the text and paste it into the tool.
In a few seconds, you will know to what degree your text is plagiarized.
I can easily remember Plagiarisma when I need a plagiarism tool because the name sounds like plagiarism.
Also, you can’t beat the price– Plagiarisma is free.
Copyscape
Based on personal experience, I find Copyscape Premium to be the most effective plagiarism software solution online, as I use the tool on a daily basis to verify my own as well as others’ content material efficiently and easily.
It offers a very easy-to-use interface, not to mention it is also quite fast and accurate.
Upon search, the tool conveniently lists any other websites with highlighted text where duplicate content is found, making it quite easy for you to correct it.
On the other hand, a common issue that many people tend to have with this tool is that you have to pay per search and the amount you are charged is directly proportional to the number of words your content has.
However, in my opinion, I find that the tool gives you good value for your money.
Another problem with Copyscape is that, unlike other tools, this one doesn’t offer grammar correction, which means that you often have to make your own corrections or use another tool like Grammarly to do so.
~
Copyscape is a great, comprehensive tool that allows you to quickly scan large batches of content.
It also allows you to perform a direct comparison of two texts or filter out results you got from another website.
The tool is very easy to use and free of charge which makes it one of the top choices for thousands of users.
Aside from checking for plagiarism, you can examine whether there’s significant duplication within your text.
PlagiarismDetector.net
My recommendation for the best plagiarism checker is https://plagiarismdetector.net/.
It catches plagiarism not just on the big name sites, but also on tiny, insignificant blogs. (It’s caught me plagiarising myself from an 11 year old blog!)
The only con is that you can only check 1,000 words at a time in the free version. (You can check up to 25,000 in the pro version for as little as $20/month.)
Even though my writing is typically 2k-3k words at a shot, I still love https://plagiarismdetector.net/, for its ease of use.
~
Back in Graduate School, I used Plagiarism Detector ( plagiarismdetector.net) to check my output’s level of plagiarism before handing it to my professor.
I like this site as I just have to input my work and it will crawl the web for any duplicates.
It also shows the percentage of plagiarism if there is any.
Aside from that, the sources come up so I know if I made something wrong in paraphrasing which sources.
It has an easy-to-understand interface and is very easy to use.
QueText
A paid plagiarism service that I love to use is www.quetext.com.
It’s thorough and detailed, to the point of driving you crazy.
However, the user interface is significantly better than the other services out there.
~
I would recommend Quetext. I like this plagiarism checker because it is low-cost ($9.99 for 100,000 words- monthly), has a very user-friendly interface, and offers a free trial which makes the checker testable and allows to see if it fits individual needs.
Quetext offers a deep content scan and text similarity detection and will enable you to cite sources that appear in your plagiarism report.
What I don’t like about this plagiarism checker is that it doesn’t have an API and supports only the English language.
Turnitin
Our company’s line of work requires us to check our collaborator’s works for any plagiarism before publishing their content.
With that said, the best checker that we can recommend is Turnitin ( http://www.turnitin.com).
It crawls the web for any similarity in your sentences, especially in academic-related websites, and comes back with a report complete with percentages and insights on how the source was manipulated.
What I love about this is that it features a color-coding output-to-source comparison which makes analysis very easy to follow.
I recommend this not only for students but also for professionals looking to publish in reputable scientific journal publications.
~
Turnitin is my number one go-to plagiarism checker for everything that I do.
I love this service because it has an extensive database of documents that it checks against and automatically uploads new ones when someone checks them online.
Through its system, it is possible to avoid plagiarism mistakes that would otherwise make my company’s marketing campaigns ineffective.
Plagiarism Checker X
The most comprehensive and encompassing plagiarism checker that I use is Plagiarism Checker X, a free tool.
This software has one of the most vast libraries for research papers and website content and it spans multiple search engines.
One of my favorite things about Plagiarism Checker X is that it allows you to compare content side by side, which is extremely helpful in picking up on similarities.
It is also very advanced in protecting user data and provides 24/7 support, so I simply love using it since it has always been a very safe and smooth experience.
SmallSeoTools
Since I am into SEO, my most recommended plagiarism checker is the SmallSEOTools.
It is one of the best plagiarism checker free tools which allows you to upload .rtf, ex, .doc, .pdf,.txt, .docx, and .odt files.
This software can check numerous web pages for duplicate text.
SmallSEOTools enables you to effortlessly exclude specific URLs.
The pros of this plagiarism checker are that it supports Dropbox and Google drive.
It also allows you to integrate website URLs and enables you to download a plagiarism report with ease.
It also supports multiple languages like French, Italian, Portuguese, Spanish, and more.
One good thing about this online plagiarism checker is that it’s free!
One of the cons when using this plagiarism checker is it has a 1,000-word limit.
It’s not suitable for long articles.
Another downside is it has a lot of distracting ads and buttons.
~
This is a great plagiarism checker that checks content line-by-line and also lets you download a plagiarism report with percentage plagiarism on it.
It’s a full combo since it also has a word counter and grammar checker.
However there are too many ads which are distracting.
DupliChecker
This is also a great tool equipped with spelling and grammar checks too.
It supports 7 formats of document and also has an option to remove plagiarism.
The web page is neater than smallseotools and also supports other languages.
ProWritingAid
ProWritingAid is a tool that enables you to test your content against multiple web pages, study papers, and publish work to ensure excellence.
Allows you to use cheat reports online or with the add-in.
Pros: It helps to organize yourself.
ProWritingAid gives more than 20 in-depth writing quotes.
You can combine it with Word, Chrome, Google Docs, Gmail, and more.
The tool is easy to use.
Supports a wide variety of files.
It helps you find your work situations including data, questions, ideas, words, and more.
ProWritingAid lets you maintain your voice control.
Cons: Lags are well known in ProWritingAid, especially if you throw in a large document or book, perhaps as many as 500 pages at a time to edit.
The cheat test must be purchased separately.
Copyleaks
Copyleaks is one of the best cheaters that allows you to work in over 100 languages online.
This app can perform extensive online searches and various details to find duplicate content.
Pros: Provides complete reports. This cheat technology checker provides an automatic measurement tool.
You can also integrate with MS Word, Google Docs, and more.
It helps you protect the content your team has posted.
Provides a fraud detection feature.
You can compare two files.
Cons:
Although I have already cancelled your subscription, I was still charged without notice.
So far I don’t know how to stop, which is a bad thing.
You no longer have to worry about the appearance of your paper.
This site is different because I feel like Copyleaks actually draws as many sources as possible to compare your paper.
Limit it instead of its imagination. I have no 100% guarantee of its results.
I hope we didn’t miss your favorite plagiarism tool and that you’ve found some new tools to try out.
