Editorial verdict

The decision on Copyscape.

Copyscape is useful for checking online text similarity and discovering potential copies of website content. The free service is limited; Premium offers text-paste searches, batch checks, a private index and API access with usage-based pricing. Text-similarity matches require human review and do not prove plagiarism. Copyscape also has a separate Premium AI Detector, whose results can be wrong. Lorezi has not independently benchmarked either system's accuracy.
