FAQ
Frequently asked questions about using T-detector as a Turnitin similarity checker.
Why doesn't T-detector save or index my paper?
Our Turnitin similarity checker performs every scan without repository storage. Your document is processed only to create the report and is never uploaded to the Turnitin database, no matter how many times you use the checker.
What does *% mean in a Turnitin AI report?
A *% result in a Turnitin AI report typically indicates that the estimated amount of AI-generated content falls between 1% and 19%. Rather than showing an exact percentage, Turnitin uses *% when the detected AI content is too limited to calculate with a high degree of precision. If the AI score is 0% or reaches 20% or more, the report displays the exact percentage. In most academic settings, a *% result reflects a low likelihood of AI-generated writing and is often considered acceptable, depending on your institution's policy.
Will my results match my school's Turnitin report?
Yes. Checking the identical version of your paper should produce AI detection and similarity results that closely match those in your school's Turnitin report. Any changes made after the check may affect the final score.
Do references count toward the Turnitin similarity score?
No. Turnitin generally excludes reference lists from similarity calculations, following the standard academic settings widely adopted 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 only English, Spanish, Japanese and Arabic.
Can I check a paper that has already been submitted to my school's Turnitin?
Yes. If your paper already exists in the Turnitin database, another similarity check may produce a high similarity score because it matches the previous submission. This is expected behavior and does not affect the AI detection results.
Which languages does T-detector support?
Turnitin provides similarity reports in more than 30 languages, while AI detection is currently limited to English, Spanish, Japanese and Arabic.
