A plagiarism checker scans your text and compares it against billions of online sources to identify similarities. Tools like Quetext follow a structured approach, starting with contextual analysis (understanding meaning), fuzzy matching (detecting paraphrased content), and conditional scoring (evaluating match accuracy). Once the scan is complete, you receive a detailed report with a plagiarism percentage, highlighted matches, and source links. Quetext also uses ColorGrade™ highlighting and a built-in citation tool to help you quickly fix issues and properly attribute sources.
