Plagiarism Checker is a free online tool that detects duplicate content in text, files, or URLs. It uses AI and NLP to identify exact and partial matches against billions of web pages and academic papers, providing a similarity report with source links. The tool supports multiple languages and is designed for students, teachers, writers, and businesses to ensure originality.
How to use Plagiarism Checker?
- To use the plagiarism checker, copy and paste your text into the input box, upload a file (e.g., .doc, .pdf), or enter a URL. Then press the 'Check Plagiarism' button to start the scan.
