Noplag Engine

Open-source plagiarism detection engine using winnowing-fingerprint matching, self-hostable

PlatformWebfreeglobal

Noplag Engine is the open-source verbatim and near-verbatim plagiarism detection core behind noplag.com, using winnowing-fingerprint matching over a corpus the user controls with every match fully traceable. It represents twelve years of plagiarism detection rebuilt in the open, letting institutions and developers run the same detection technology on their own hardware instead of a hosted service.
