What is plagiarism check?
A plagiarism check for a research paper compares the manuscript against published articles, web pages and other submissions to produce a similarity index and a report of matching text. Journals use the same software, iThenticate, when screening submissions. Frontier Publishers runs the check before you submit and adds expert feedback on which matches are acceptable, such as methods phrasing and properly cited quotations, and which need to be revised.
Service overview
Most journals screen every submission with similarity software, and a high score can lead to immediate rejection even when the overlap is unintentional. Checking first lets you fix problems on your own terms.
After your order is confirmed, your file is scanned with iThenticate and our publication experts add detailed feedback. You get the complete report and an explanation of which matches are likely to concern an editor.

Questions
Plagiarism check questions
We use iThenticate, the similarity-checking software used by most major publishers to screen submissions.
There is no universal threshold. Many journals look more closely above 15–20% overall or at any single source above a few percent. Context matters more than the number, which is why our experts explain each significant match.
The plagiarism check identifies sentences that need attention and advises how to reduce the similarity index; the changes themselves are made by the author. If you want the text rewritten for you, choose our academic rewriting service.
No. Checks are run so that your manuscript is not saved to a repository, so it will not match against itself when the journal screens it.
