Copyleaks is an AI-powered content-integrity platform that scans text (and source code) for plagiarism checker, paraphrasing, and AI-generated content. It’s widely used by educators, publishers, and businesses and offers API access, LMS integrations, and multi-language support.
What Copyleaks does (features at a glance)
- Plagiarism detection: Compares submitted text against the web and proprietary databases to find exact matches and paraphrased content.
- AI content detection: Detects content likely generated by models (ChatGPT, Gemini, Claude, etc.), with Copyleaks reporting very high detection rates for many use-cases.
- Code plagiarism detection: Specialised checks for source code similarity and reuse.
- Multi-language support: Detection in 100+ languages.
- Integrations & workflow: API for automated checking, LMS integrations for classrooms, and dashboard reports for institutions.
- Detailed reports: Interactive reports highlighting matches, percent similarity, matched sources, and guidance for instructors/editors.
How Copyleaks works (simple)
You paste text, upload a document, or submit a URL. Copyleaks tokenizes and analyzes the content, compares it against massive web indexes and its databases, flags likely match (including paraphrased text), and generates an interactive report showing matched passages and sources. For large-scale or automated use, you can call their API or integrate Copyleaks into your LMS.
Accuracy & real-world findings
Copyleaks markets itself as an award-winning detector for both plagiarism and AI content. Independent reports and studies (including Copyleaks’ own analyses) indicate it is effective at detecting copied and AI-influenced text, though, as with any detection tool, no detector is perfect and results should be interpreted as guidance rather than absolute proof. (See official AI-detector claims and independent reporting.)
