Direct answer
What is Copyleaks?
Copyleaks scans written text and digital images to identify AI-generated content, copyright infringement, and plagiarism across more than 30 languages for AI detection and 100 languages for plagiarism matching.
Copyleaks provides content authenticity and plagiarism screening across text, images, and code. Built for higher education institutions, publishers, and enterprises, the system analyzes text to detect passages generated by large language models—including ChatGPT, Gemini, Claude, and DeepSeek—while simultaneously matching against billions of web pages, journals, and private repositories for copied phrasing. Beyond basic text analysis, Copyleaks identifies obfuscation techniques such as paraphrasing and character manipulation designed to bypass traditional plagiarism filters. Detection outputs are integrated into a single report when analyzing text, showing human, AI, and matched source distributions. Dedicated image scanning inspects digital graphics for AI generation artifacts. Organizations can access Copyleaks through a cloud interface, browser extensions, a Google Docs add-on, API integrations, and direct Learning Management System (LMS) connectors including Moodle and Instructure.
Copyleaks combines GenAI detection across major language models with broad multi-language plagiarism scanning and image authenticity checks in one reporting ecosystem, backed by standard LMS and API integrations.

Frequently asked
Copyleaks FAQ
Can Copyleaks detect both AI content and plagiarism in the same scan?+
Yes, for text documents. Copyleaks combines AI text detection and web/academic plagiarism matching into a single unified report. However, for image detection, the tool only evaluates whether an image was AI-generated and does not check for image copyright infringement or duplicate images.
Which AI models does Copyleaks flag?+
The platform is engineered to detect content generated by leading models including ChatGPT, Google Gemini, Anthropic Claude, and DeepSeek, with detection updated as newer models are deployed.
How does Copyleaks credit consumption work?+
Copyleaks uses a unified credit model across its plans. On self-serve tiers, credits can be spent on scanning text (for example, up to 300,000 words on the Personal plan) or scanning images (up to 1,200 images), with additional credits available for purchase on demand.
Does Copyleaks use submitted documents to train its AI models?+
By default, Copyleaks may use submitted content without personal identifiers to improve services and train its models. However, direct customers can opt out of model training by contacting customer support, and enterprise customers can elect to opt out administratively.
What security and privacy standards does Copyleaks meet?+
Copyleaks infrastructure is hosted on Google Cloud with data centers in the US and Germany. It adheres to GDPR, acts as a School Official under FERPA for educational institutions, maintains SOC 2, SOC 3, and PCI DSS compliance, and encrypts data at rest using AES-256.
