|PlagScan.com inspires confidence, even if its name doesn't trip off the tongue. Its website is smart and tidy – it's clearly laid out and not at all overwhelming. The developers of the plagiarism scanner seem genuinely proud of it – of course a lot of similar websites play themselves up – yet with this one there seems to be genuine sincerity behind the wording. For example, its developers are so confident its users will be satisfied that they offer a money-back guarantee. Additionally, its home page features news that it has been rated as the number 1 scanner by TopTenReviews which, after some checking, does not appear to be affiliated with the website in anyway.Its various subscriptions are a little confusing and quite technical. Users buy credits in Euros and these are converted into PlagPoints, but, as its Pricing Policy page demonstrates, this is as simple as it gets:The "PlagPoint" : Costs are determined by the number of words in a document. We settle this via a credit point system, in which 1 PlagPoint () allows the analysis of 100 words or fraction thereof, while at least 10 are consumed per document (1-1000 words = 10, 1001-1100 words = 11, 1101-1200 words = 12, etc.).
However, to the website's credit, it gives away 25 "PlagPoints" to every user who registers with them (and this in itself is a simple process). The free credits are equivalent to scanning up to 2,500 words which, by comparison to other subscription based websites, is pretty generous.
Documents are uploaded online and these can be stacked up so multiple searches can take place at once – a handy feature, and at a glance it's possible to see which documents have passed and which have failed. Each scan takes about a minute for a small sample of text, no bigger than one large paragraph. Clicking on each result creates a separate report within the browser and these can be downloaded and shared with ease.
After such a build-up it is somewhat disappointing that the scanner only detected plagiarism in three out of the six test documents. It detected blanket plagiarism, where none of the words had been changed, as well as in documents where some of the words had been omitted and where words had been removed altogether. It did spot that an upload had plagiarised an online pdf; however, if failed to correctly identify the website it was taken from and therefore failed the test (plagiarism must, after all, be proven). It also failed to detect an entirely paraphrased submission and wasn't able to detect the plagiarism of an electronic book.
Looking back through the analysis of the scanner carried out by TopTenReviews, PlagScan is awarded 9/10 for accuracy, yet in our results it scored an equivalent 6/10. One possible reason for this is that TopTenReviews perhaps only tested the scanner using samples taken from websites, overlooking online pdfs and electronic books; however, students cheat using a variety of online sources so it's important to include these in any tests being carried out.
The results therefore are decidedly mixed for PlagScan – despite its complex algorithms there are entirely free online scanners which performed better in tests – accordingly, if checking for plagiarism, you might want to consider taking up PlagScan's kind offer of free credits – but also run your paper through a few other free scanners too.
