Anti Plagiarism Tools

Everyone’s heard of Copyscape, the super duper plagiarism detection tool. Sometimes it’s the bane of our lives (like when clients who pay 1 cent a word want you to check every article on Copyscape even though you KNOW that you never plagiarise). At other times, it’s a useful tool, such as when you’ve subbed out some work and want to make sure that nothing that has your name attached to it will turn out to be plagiarised.

Most of the time, I find it useful. I signed up for a premium account so I could check blocks of text rather than just URLs. (Five cents a time is a small charge to protect my good name.) The fact is, sometimes you have to use it, but what do you do if it isn’t working? This recently happened to me. I needed to check some work quickly and Copyscape was throwing up error messages. Thanks to the wonders of Google, I quickly found a few alternatives, which I’m putting here in case you can use them.

Article Checker

Article Checker was the most useful of the alternatives I found. You can paste in a block of text and check it against the sites indexed on Google and Yahoo. It’s lightning quick and appears to be accurate. I don’t know how long a text has to be before it flags. I was checking 400 word articles and it seemed ok. I’ve used this tool a couple of times and it’s never found any plagiarism but that doesn’t mean it won’t. Many other writers I know use this tool because it is free. A good feature is that you can upload files for checking, which could be good if you are doing rewrites.

Plagiarism Checker

The Plagiarism Checker was originally designed as a student project at the University of Maryland. Like the other tools, it works by pasting some text into a box and hitting enter. Then you get a list of results for phrases. Interestingly, this check said the article I checked with Article Checker was almost certainly plagiarised. It brought up a list of suspicious phrases and then you could click on a link for more information. That took me to a Google search page which found … drumroll, please … no plagiarism. So I wouldn’t rely on that tool.

DupeCop

DupeCop allows you to compare two pieces of text through its free online duplicate content checker, or to compare up to four versions of spun articles through its spun article checker. I haven’t tested these yet, but this looks like a good service. There are desktop versions of both checkers too.

Other Tools

If you just want to compare web pages, then try DuplicateContent, which has an online URL comparison engine. There are also a few other tools, which I haven’t tested, but am listing in case you want to. DocCop has both free and paid services, but you will need to register to use either service. DupeFree Pro is a piece of free software (I’m still waiting for my registration details to arrive). Finally I-thenticate is a web based product used in business and education. It’s not free. In fact, you have to register just to find out the price, which is why I didn’t.
