Frequently Asked Questions
Everything about Thentify and iThenticate reports.
1. Will my manuscript be indexed in the iThenticate or Turnitin database?
No. Thentify iThenticate is designed for confidential similarity screening only. Your manuscript is never stored, indexed, or added to external repositories or searchable databases.
2. What does *% mean in an iThenticate AI writing report?
iThenticate may display *% when AI content is estimated between 1–19%, reflecting possible uncertainty. Scores of 0% or 20%+ are shown exactly. A *% is generally acceptable unless strict requirements apply.
3. Will my results match journal or institutional screening results?
Results are usually similar when the same manuscript version is reviewed. However, revisions, formatting changes, and updated databases may affect final results.
4. Are references included in the iThenticate similarity score?
No. Reference lists and bibliographies are excluded from similarity calculations following standard academic publishing and manuscript screening practices.
5. Why are iThenticate AI detection results different from other tools?
Different AI detection systems use different models and thresholds. iThenticate follows a more conservative approach designed to reduce false positives in academic writing.
6. What happens if I don't download my report within 24 hours?
Reports are automatically removed after 24 hours to help protect unpublished research and manuscript confidentiality. A copy is also sent to your registered email.
7. Can I check a manuscript already indexed in a journal database?
Yes. If the manuscript already exists in searchable databases or repositories, the similarity score may be higher due to indexed content.
8. Why was my manuscript flagged as AI-generated if I wrote it myself?
AI detection is probabilistic and may flag highly structured or heavily edited academic writing. Writing assistants and extensive revisions may also influence results.
9. Why do AI indicators change after manuscript revisions?
AI detection evaluates the document as a whole. Even small revisions can affect how surrounding sections are interpreted during analysis.
10. Which languages does Thentify support?
Thentify similarity screening supports more than 30 languages, including English, Chinese, Spanish, German, and French. AI writing detection currently supports English and Spanish.
11. Why wasn’t my AI report generated?
AI reports may not generate if documents exceed 29,999 words, contain fewer than 320 words, or use unsupported languages.
12. Can AI detection results change over time?
Yes. AI detection models are continuously updated and refined, which may affect future analysis results for newly reviewed manuscript versions.
