Turnitin is an American commercial, Internet-based plagiarism detection service which is a subsidiary of Advance., Founded in 1997, universities and high schools typically buy licenses to use the software as a service website, which checks submitted documents against its database and the content of other websites with the aim of identifying plagiarism. Results can identify similarities with existing sources, and can also be used in formative assessment to help students learn to avoid plagiarism and improve their writing., Students may be required to submit work to Turnitin as a requirement of taking a certain course or class. The software has been a source of controversy, with some students refusing to submit, arguing that requiring submission implies a presumption of guilt. Some critics have alleged that use of this proprietary software violates educational privacy as well as international intellectual-property laws, and exploits students' works for commercial purposes by permanently storing them in Turnitin's privately held database., Turnitin's parent company, iParadigms LLC, runs the informational website Plagiarism.org and also offers a similar plagiarism-detection service for newspaper editors and book and magazine publishers called iThenticate. Other tools included with the Turnitin suite are GradeMark and PeerMark . Turnitin released the WriteCycle Suite on February 3, 2009, which bundles the Originality Checking service with its GradeMark online grading tools and PeerMark tools. Turnitin released Turnitin2 on September 4, 2010, dropping the "WriteCycle" nomenclature., In March 2019, Advance acquired the company for US$1.75 billion.
