|Copyscape's website has a simple, clean looking design that isn't too fussy or complicated whilst not appearing basic or outdated. In addition to the development of a plagiarism scanner, the website also offers a facility for checking for plagiarised content on webpages by scanning the content of individual URLs.The plagiarism scanner which features on the website cannot be used at all without some kind of subscription, however, purchasing credits for it is a much simpler process than other, similar websites – there aren't multiple options to choose from, it's as simple as paying $5 for 500 credits (the minimum number) up to $500 for 50,000 credits. The credits are valid for a year which, in the case of the latter option, would mean a user would have to scan 192 documents a day for five days a week to use them all up!
The scanner itself is fairly basic but, again, this isn't necessarily a bad thing. However, anything being checked has to be copied and pasted directly into the browser and this would be a drawback for anyone checking lots of documents – incorporating a file upload facility into the browser could potentially save some users lots of time and, considering people pay to use this scanner, it's not a lot to ask for.
During tests, Copyscape's plagiarism scanner performed well, identifying plagiarism in four out of the six test documents. It detected blanked plagiarism where text had been copied and pasted off another website as well as detecting work plagiarised from an online pfd. In addition, it spotted plagiarised work where some words had been changed and where some of the words had been omitted. The checker did not detect an entirely paraphrased article, nor did it spot the plagiarism of an ebook.
Copyscape is slightly more accurate than the average plagiarism scanner, although there are still free scanners out there which identify as much plagiarism, so it's still probably worth saving your pennies unless you've got money burning a hole in your pocket.
