Protecting originality since 2006

Our story

Plagium went online in 2006 with a simple idea: paste a text, and we tell you where else it appears on the web. Long before plagiarism checkers were common, teachers and journalists were using it to verify authorship in seconds.

Twenty years later, the question changed. It is no longer only about who copied whom, but also about who wrote at all. So Plagium grew into two detectors that work together: similarity search across the web, news and academic archives, and AI detection that estimates how likely a text is to be machine written.

What has not changed is the way we answer. A verdict you can read at a glance, evidence you can check yourself, and honesty about what the numbers can and cannot prove. Plagium is a Septet Systems Service.
