Scribbr
Academic plagiarism checker on demand, no subscription
Overview
Scribbr offers a per-document plagiarism check with no monthly subscription: you pay per submission, from ~€20 to ~€40 depending on word count. The engine relies on iThenticate, the same database as Turnitin, ensuring very broad coverage (99 billion web pages, 8 million academic publications). The report details matching sources.
Scribbr is best known for academic editing and proofreading services, and the plagiarism checker is a natural complement. It includes a basic AI content detector. A French-language interface is available at scribbr.fr.
Our verdict
Scribbr suits a student or consultant needing to check a single document without subscribing. For regular use, per-document costs quickly mount: a Copyleaks or Originality.ai subscription becomes more economical. Not suited for SMEs producing content in volume.
