Plagiarism+Checkers


 * [|Plagiarisma] is a free tool that teachers and students can use to detect possible cases of plagiarism. There are a few ways that you can use [|Plagiarisma]. The easiest way to use Plagiarisma is to copy and paste a chunk of text into the Plagiarisma search box. You can also upload documents (RTF, Doc, PDF, HTML, ODT) to be scanned by Plagiarisma. The third option is to type a url into the search box to have Plagiarisma scan for possible cases of plagiarism. Whichever option you use, Plagiarisma will return a list of urls containing possible plagiarism matches.
 * The [|Plagiarism Checker] (@http://www.dustball.com/cs/plagiarism.checker/), created as a project for the University of Maryland, is an easy-to-use tool for detecting plagiarism. Simply enter a chunk of text into the search box and the Plagiarism Checker will tell you if and from where something was plagiarized.
 * [|Plagiarism Checker.com] works just like many similar services. To use it, simply type or paste text into the search box and Plagiarism Checker will tell you if and from where something was copied. (Note: the name is similar to the one above, but they are produced by different organizations).
 * [|Doc Cop]offers a free service for checking small documents and a free service for checking documents against each other. Doc Cop also offers a fee based service that will check large documents and do a more comprehensive check than that offered for free.
 * [|Paper Rater] is a free service designed to help high school and college students improve their writing. [|Paper Rater] does basic spelling and grammar checks, but the real value of [|Paper Rater] is that it tells students if their papers have elements of plagiarism. [|Paper Rater] scans students' papers then gives students an estimate of the likelihood that someone might think that their papers were plagiarized.
 * [|Plagiarism.org], produced by the same people that produce the commercial plagiarism detection software Turn It In, has a [|free learning center] for students and teachers. Plagiarism.org's learning center includes tips about avoiding plagiarism, definitions of plagiarism, and explanations of when you do or do not have to cite a reference. Plagiarism.org also hosts two recorded webinars addressing the topic of plagiarism in schools and how teachers can educate their students about plagiarism.
 * Article Checker, a very similar plagiarism detection tool which checks for duplicate content using either Google or Yahoo. Both the search engines can be used to compare results. Input of content is through a text area box or by giving the URL of a webpage. The checker functions by taking blocks of text and running it through the search engines. A Google Alert can be set up for the positive matches with a click.
