About Copyleaks
Copyleaks AI Content Detector is used by a large number of organizations globally, including Fortune 500 companies and major universities. It provides sentence-level AI detection, flagging individual sentences rather than just an overall document score.
Copyleaks is used by universities, corporate compliance teams, and publishers to detect both AI-generated and plagiarized content. Its AI detector analyzes text at both the sentence and document level, looking for statistical patterns across multiple dimensions. AI2Human's Heavy mode restructures sentence-level phrasing and rhythm throughout a document — the level of detail Copyleaks' sentence-by-sentence analysis is built to notice.

Copyleaks — Frequently Asked Questions
What is Copyleaks AI Content Detector?
Copyleaks AI Content Detector is a tool that identifies AI-generated content at both the document and sentence level. It's used by universities, publishers, and corporations for content compliance.
Does Copyleaks flag specific sentences as AI?
Yes. Copyleaks performs sentence-level detection, highlighting specific sentences it classifies as AI-generated. AI2Human's Heavy mode addresses this by restructuring at the sentence level, not just the document level.
Does AI2Human guarantee a specific Copyleaks score?
No — Copyleaks' model is proprietary, and no tool can promise a fixed result against it. Heavy mode is built to apply the most thorough sentence-level rewriting we offer. Institutions set their own internal thresholds; check your institution's actual policy rather than relying on any single number.
Is Copyleaks used by universities?
Yes. Copyleaks is used by universities in the US, UK, Australia, and elsewhere for academic integrity checking. Many institutions use it alongside Turnitin.
Does AI2Human affect Copyleaks plagiarism detection?
Structural rewriting changes phrasing, which may affect similarity-matching scores as a side effect. It does not remove the need to cite sources — any idea, quotation, or finding drawn from another work still needs a citation, and plagiarism rules apply exactly as before.
