Turnitin (also known as Turnitin.com) is an Internet-based plagiarism-detection service created by iParadigms, LLC. Institutions (typically universities and high schools) that have bought licenses submit essays to the Turnitin website to check for plagiarism. Students may be required by schools to submit essays to Turnitin, as a deterrent to plagiarism. This has been a source of criticism, with some students refusing to do so in the belief that requiring it constitutes a presumption of guilt. Additionally, critics have alleged that use of the software violates educational privacy and intellectual property laws.
