A plagiarism checker is an essential online tool that scans written content to identify potential instances of plagiarism, where text closely matches existing sources. It compares submitted text against a vast database of academic papers, websites, and other written materials. When matches are found, the checker highlights the similarities and provides a percentage indicating the level of originality.
This helps writers and educators ensure content is free from unauthorized copying and properly cited. It’s widely used in academic institutions, publishing, and content creation to maintain integrity and prevent intellectual property theft. Reliable plagiarism checkers assist in upholding academic and professional standards.
