 Plagiarism Check Service

When you submit a manuscript to any reputable journal, it will be scrutinized for plagiarised content. Plagiarism, intentional or otherwise, is viewed as a violation of ethics and, if detected in your paper, leads to automatic rejection. Besides, plagiarism can tarnish your reputation and credibility as an author.To avoid such situations, HNPI's Plagiarism Check service helps you identify areas in your manuscript that might be flagged as plagiarism.See the source image

Currently, we are using turnitin for Plagiarism detection.


  • Our price for any article is USD 20.00 up to 10,000 words/ BDT 1600.00
  • For a full thesis USD 50.00/ BDT 4000.00
