What is Plagiarism Detection?

Plagiarism detection is the process of comparing your document against billions of online sources, academic journals, books, and institutional repositories to identify matching or closely similar text without proper attribution.

  • Failing grades, suspension, or expulsion risks
  • Theses rejected due to high similarity scores
  • Journal manuscript rejections
  • Loss of academic credibility
  • Missed learning opportunities
