Tips for Using Plagiarism Checker

Don't wait until the last minute. Check your work throughout the writing process to catch and fix issues early.

2 Review Highlighted Sections

Manually review all flagged content. Some matches may be common phrases or properly cited quotations.

Always cite your sources correctly using the required format (APA, MLA, Chicago, etc.) to avoid unintentional plagiarism.

4 Paraphrase Effectively

When paraphrasing, change both the words and the sentence structure. Don't just replace words with synonyms.
