Frequently asked questions

Simple answers to your questions

How do I check plagiarism in a document?
Upload or paste the document into a plagiarism detector, run the scan and review the similarity findings. Examine each match to determine whether it is quoted, cited, common language or potentially copied material.
What is the difference between plagiarism and similarity?
Similarity means wording resembles content from another source. Plagiarism involves presenting someone else’s work or ideas as your own without appropriate acknowledgment, so not every similarity match is plagiarism.
Can I check an essay for plagiarism before submitting it?
Yes. A pre-submission review can help you find passages that need citations, quotation marks, rewriting or source verification before the work is submitted.
What should I do when a plagiarism detector finds a match?
Read the matching passage and source, then determine whether attribution is present and appropriate. You may need to quote the source, add a citation, revise the wording or remove the passage.
