Plagiarism Checker then compares these parts against a huge database of published materials, such as academic journals, books, articles, and websites. It generates a report highlighting possible plagiarism instances based on matches and similarities.

Database Comparative Analysis

In the database comparison step, the plagiarism checker examines the submitted text against its internal database. It may include previously submitted documents, academic papers, and other publications. As a result, it can identify self-plagiarism or duplication within the same document.

How to Cite Sources

Plagiarism checkers not only detect potential plagiarism but also assist with proper citation. They often offer suggestions and guidelines for properly citing sources and avoiding plagiarism. These tools ensure academic honesty by encouraging users to cite their sources correctly.
