Turnitin is an online plagiarism detection service that is widely used in educational institutions. This is an app designed to help instructors and students ensure academic integrity by checking for potential plagiarism in written work.

When a student submits an essay, research paper, or other written assignment via Turnitin, the app compares that text to an extensive database of sources, including websites, academic journals, and previously submitted papers. It looks for similarities in the wording and structure of submitted works to the content it finds in its database.

Turnitin produces an "Originality Report" which provides a similarity score indicating the percentage of submitted works that match the source. This report highlights suitable text and provides links to identified sources, enabling instructors to review and assess the integrity of the work. Instructor can use this information to determine whether content is properly cited and cited or if plagiarism has occurred.

In addition to plagiarism detection, Turnitin also offers features for providing feedback and grading assignments. Instructors can use the platform's online assessment tool to provide comments, suggestions, and corrections directly on submitted documents.

It should be noted that Turnitin is a dedicated software application and requires a subscription or institutional access to use. It is primarily used by educational institutions such as schools, colleges, and universities to promote academic integrity and ensure students properly cite and acknowledge the sources they use in their writing.
