Frequently Asked Questions
What counts as a plagiarism match?
The scanner looks for identical word sequences (verbatim copying) as well as close paraphrasing where sentence structures match existing online publications.
Can I exclude quotes and references?
Yes, you can toggle exclusion for quoted passages and bibliographic lists to avoid inflating similarity scores.
What is an acceptable similarity score?
Scores under 15% generally represent standard idioms and terminology. Scores above 30% usually suggest sections that need revised paraphrasing and formal citations.
