FAQ
Frequently asked questions about using T-detector as an online Turnitin plagiarism checker.
Why doesn't T-detector save or index my paper?
Our Turnitin plagiarism checker online performs every scan without repository storage. Your document is processed only to create the report and is never uploaded to the Turnitin database, regardless of how many times you use the service.
What does *% mean in a Turnitin AI report?
A *% result in a Turnitin AI report generally means the estimated amount of AI-generated content falls between 1% and 19%. Rather than displaying a precise percentage, Turnitin uses *% when the detected AI content is too limited to measure with a high degree of accuracy. When the AI score is 0% or reaches 20% or higher, the report displays the exact percentage. In most academic settings, a *% result indicates a low likelihood of AI-generated writing and is often acceptable, depending on your institution's policy.
Will my results match my school's Turnitin report?
Yes. If you check the identical version of your paper, the AI detection and similarity results should closely match those generated by your school's Turnitin account. Any revisions made after the scan may change the final score.
Do references count toward the Turnitin similarity score?
No. Reference lists are generally excluded from Turnitin similarity calculations under the standard academic settings commonly 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 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 return a high similarity score because it matches the previous submission. This is expected 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 available only for English, Spanish, Japanese and Arabic.
