Are my submissions to iThenticate kept private? 
Yes. Submissions are added to a private, secure database that is only accessible by your own account. Unlike many free plagiarism checker services, iThenticate does not share or resell uploaded files. Your submissions are not searchable by any other account, nor used by any other Turnitin service.
 
Can I delete my submissions from iThenticate?

What is the maximum size of a document?
A single file can be up to 25,000 words, which accommodates the average length of a research paper. If your document is larger, you can purchase multiple credits and segment content in parts of 25,000 words or less.

What is a revision?
A revision is when you submit a manuscript that you have already uploaded to iThenticate and you have either revised it or added more material to it and want to check your manuscript again.

How many times can I submit a manuscript for a plagiarism check?
After you submit your document once, you may resubmit it a maximum of five times. If your revised manuscript is substantially different than the first submission, iThenticate may ask you if you would like to submit the revision as a new manuscript.

Can editors see my Similarity Report?
No. iThenticate gives you your own personal account so that you can check for plagiarism privately. This means that no one can access it but you. If you would like to share your report, you can print it out or download to HTML and email.

Can I submit two documents for comparison?
A chapter from my book and another article published in a journal. I don't want to compare with the database. Yes, iThenticate offers document to document comparison. This functionality is only available in iThenticate's annual licensing edition. Please contact us for more details.


Reports

What do iThenticate reports highlight?
iThenticate identifies material that matches text from documents found in our extensive database. Highlighted text will include text that has been properly quoted and cited so it is not necessarily plagiarized. You will need to verify that every highlighted section has been properly quoted, summarized or paraphrased. As a result, iThenticate makes it easier for you to identify and attribute any material in that may contain unintentional plagiarism.

How long will I have to wait until my results are ready?
Results are usually delivered within one minute to several minutes, depending on document length.

How will I know if my results are ready?
While this analysis is in progress, you will see the word "pending" in the report column next to the title of your manuscript. When your results are ready, you will see a percentage, or "Similarity Index" in the report column next to the title of your manuscript.

How do I see my results?
To see your results, click the "Similarity Report" icon in the report column next to the title of your manuscript.

What does the percentage mean?
The results include a percentage score, called a "Similarity Index", which indicates how much of the document matches other sources. Please note that iThenticate does not determine whether a manuscript contains plagiarism. The service identifies content in a submitted manuscript that matches other sources, primarily to encourage the author of the manuscript to check that other sources have been properly cited. Watch a demo

What do the highlighted boxes mean?
The results include number-coded and color-coded highlighting of parts of the manuscript that correspond to matching sources in the iThenticate database. You are encouraged to look carefully at these portions to determine whether other sources have been properly cited.
