Copyleaks

Overview

Copyleaks started as a plagiarism checker and added AI-text detection as the market shifted, so it now pitches itself as a combined integrity platform for universities, publishers and enterprises rather than individual users. Its stronger card is breadth: plagiarism checking and detection across many languages, an LMS and API integration layer, and source-code plagiarism checks that most rivals skip. Pricing is subscription and credit based, oriented to institutions buying seats rather than someone running a single check. As an AI detector specifically, it carries the same fundamental limits as everything else in the category. The likelihood score is a statistical inference, not evidence, and Copyleaks itself has been the subject of research and reporting on false positives. It tends to flag human writing as AI more often than users expect, and the burden falls hardest on non-native English writers whose phrasing reads as 'templated'. Use it as a plagiarism and workflow tool with confidence; treat its AI verdict as a prompt to investigate, never as a finding.
