Copyleaks

What is Copyleaks?

Copyleaks is an enterprise-grade AI content detection and plagiarism checking platform founded in 2015 by Alon Yamin and Yehonatan Bitton. Headquartered in New York, the company serves universities, publishers, legal firms, and enterprises that need to verify content authenticity at scale. Unlike consumer-focused AI detectors, Copyleaks positions itself as an institutional solution with deep integrations into learning management systems (LMS) like Canvas, Moodle, Blackboard, Brightspace, and Schoology, making it a direct competitor to Turnitin in the academic integrity market.

The platform offers three core products. The AI Content Detector identifies text generated by ChatGPT, Claude, Gemini, Llama, and other large language models, claiming 99.1% accuracy with a low false positive rate. The Plagiarism Checker compares submitted text against billions of web pages, academic journals, and internal databases to flag copied or paraphrased content. Codeleaks, their source code analysis tool, detects plagiarized and AI-generated code while also identifying open-source license violations — a capability that distinguishes Copyleaks from most competitors in the AI detection space.

Copyleaks supports over 100 languages for plagiarism detection and multiple languages for AI detection, making it one of the most multilingual platforms in the category. The API enables automated content screening within existing workflows, and the platform offers enterprise features including Gen AI Governance tools for organizations that need to monitor and control how AI-generated content is used across their operations. The Writing Assistant add-on provides grammar and style corrections alongside detection results.

However, independent research paints a more nuanced picture of accuracy. A June 2023 study found Copyleaks achieved 93% sensitivity for GPT-4-generated content but struggled with texts that had been modified by humans after generation. Like all AI detectors, Copyleaks faces the fundamental challenge that paraphrased, lightly edited, or human-refined AI content is significantly harder to detect. The platform works best on unedited, raw AI output and may produce false positives on formulaic or non-native English writing. Copyleaks raised $7.75 million in funding in 2022, signaling continued investment in the AI integrity space.
