What is Copy Detect?

Copy Detect is an online plagiarism checker that scans text against web sources and academic databases to identify potential copied content. It's designed for students, educators, content creators, and organisations who need to verify the originality of written work before submission or publication. The tool provides a straightforward way to check for unintentional or intentional plagiarism by comparing text against billions of web pages and published sources. It operates on a freemium model, allowing users to check documents for free with basic functionality, whilst paid tiers offer more detailed reports and higher submission limits.
