Turnitin

Overview

Turnitin is the incumbent in academic integrity — a similarity-checking service embedded in universities and schools for decades, sold through institutional licences rather than to individuals. It added an AI-writing indicator to its existing plagiarism and grading workflow, so for most instructors it appears as a percentage inside the same Feedback Studio they already use for citation checking. Its real strengths are institutional: a vast comparison database, deep LMS integration and established grading tooling. The AI detector, though, is the most scrutinised feature it has ever shipped, and for good reason. Independent testing and several universities have raised concerns about false positives; some institutions have disabled or de-emphasised the AI indicator over reliability worries. The category caveat is not optional here — it is the story. The score is a probabilistic estimate, not proof of misconduct; false positives disproportionately affect non-native English writers; and a number inside Feedback Studio should open an academic-integrity conversation, never close one. Treat it as a flag to investigate with the student, not as evidence.
