Plagiarism Checker

Plagiarism Checker is an online tool that scans documents and text to identify content matching material published elsewhere. You upload a document or paste text directly, and the tool compares it against a database of web pages, research papers, and academic sources. It highlights matching sections in your document and provides a similarity score showing what percentage of your content overlaps with existing material. This helps you identify unintentional duplication and ensure proper attribution. The tool is designed for multiple audiences, including students checking assignments before submission, educators verifying the originality of student work, content creators ensuring their articles are unique, and researchers confirming that citations are handled correctly. The free tier includes basic scanning with file size limits, allowing you to check a limited number of documents each month. Paid plans remove these restrictions, offering unlimited scans, support for larger file uploads, complete reports that break down matched sources, and faster processing. The straightforward interface requires minimal setup, making it accessible to users of all technical levels.
