Turnitin AI Report vs Similarity Report

The Turnitin AI report's AI score estimates the share of qualifying prose flagged as likely AI-generated. 0% means none was flagged; *% hides an estimate from 1–19%; 20–100% is a displayed estimate; and no AI percentage means no usable AI result was produced, not 0%. The Turnitin similarity score instead measures text matching sources. Neither result alone proves misconduct.

Frequently Asked Questions

Standard Check requests an AI Detection Report and a separate Similarity Report. An AI Writing Report is returned only when Turnitin generates one for the qualifying submission.
AI Score estimates how much qualifying text may look AI-generated. Similarity Score measures overlap with published and web sources. They are different metrics — a higher AI Score does not mean a higher Similarity Score, and vice versa.
TurnitChecker accepts PDF, DOC, and DOCX files containing 400–28,000 words and no more than 10 MB. AI Writing Reports are available for qualifying content in English, Spanish, Japanese, Modern Standard Arabic, German, Dutch, and Turkish. These are TurnitChecker service limits, and meeting them does not guarantee a report; generation and delivery depend on Turnitin's processing result.
TurnitChecker is designed for private pre-submission checks. Your document is processed only as needed to provide the requested report and is not retained for routine long-term storage on our platform. Submissions are configured not to be added to Turnitin's student paper repository during processing.

Review with confidence before you submit.
