FAQ
Common questions about using T-detector and our Turnitin AI Writing Detection tool.
Why doesn't T-detector save or index my paper?
Our Turnitin AI writing detection tool performs every check without repository storage. Your paper is analyzed only to create the report and is never uploaded to the Turnitin database, no matter how many times you run a check.
What does *% represent in a Turnitin AI report?
In Turnitin AI reports, a *% result usually indicates that the estimated AI-generated content falls between 1% and 19%. Rather than displaying a precise percentage, Turnitin uses *% when the detected amount is relatively small and cannot be measured with high confidence. If the AI score is 0% or 20% and above, the report typically displays the exact percentage. In most academic environments, a *% result suggests a low likelihood of AI-generated content and is often considered acceptable, depending on your institution's policies.
Will my results be the same as my school's Turnitin report?
Yes. If you analyze the identical version of your paper, the AI detection and Turnitin similarity results should match those generated through your school's Turnitin system. Any revisions made afterward may change the final score.
Are references included in the Turnitin similarity score?
No. Reference lists are generally excluded from Turnitin similarity calculations, following the standard academic settings widely used by universities and scholarly journals.
Why wasn't my Turnitin AI report generated?
AI analysis may not be available if your document is written in an unsupported language or contains fewer than 320 words or more than 29,999 words. Turnitin AI detection currently supports English, Spanish, Japanese and Arabic documents only.
Can I check a paper that has already been submitted to Turnitin?
Yes. However, if your paper is already stored in the Turnitin database, running another similarity check may produce a high similarity score because it matches the previous submission. This does not affect the AI detection results.
What languages does T-detector support?
Turnitin supports similarity reports in more than 30 languages, while its AI detection feature is currently limited to English, Spanish, Japanese and Arabic.
