Turnitin AI Writing Detection
What Turnitin AI Writing Detection is
Turnitin AI Writing Detection is a paid web service for educators and institutions reviewing student submissions. It identifies text that may have been generated or modified by AI writing tools, then reports an overall percentage of qualifying text and highlights relevant passages. Detection can also flag likely AI-generated writing altered by an AI paraphraser or bypasser. Access is available with Turnitin Originality when licensed and enabled; iThenticate customers can license it as an add-on. Reports require an accepted file under 100 MB containing 300 to 30,000 words of long-form prose in a supported language. The listed languages are English, Spanish, Japanese, and Arabic. Feedback Studio offers LTI 1.3 integrations including Blackboard, Canvas, and Moodle. Microsoft Teams requires Feedback Studio integration and an Originality license. Reports export to PDF, with API access, web source matching, academic source matching, and LMS integration listed. Turnitin was founded in 1998 and is headquartered in Oakland, California.
