Copyleaks, a recognized leader in AI-powered content originality and authenticity, has been declared the most accurate AI detector in the market following an extensive, independent evaluation by Business Insider. Tested against eight leading tools, Copyleaks demonstrated unmatched precision in identifying both human- and AI-generated text across various professional and academic documents, including essays, résumés, and cover letters. This finding reinforces Copyleaks’ position as a crucial tool for maintaining transparency and accountability in the rapidly expanding digital content landscape. The company’s core advantage lies not only in detection but also in providing granular, phrase-by-phrase transparency, confirming its status as the industry's gold standard.
Copyleaks was recognized by Business Insider as the most accurate AI detector overall among eight tools tested.
The evaluation covered various content types (essays, résumés, cover letters) with content generated or edited by models like ChatGPT, DeepAI, and Claude.
Copyleaks' solution offers unmatched transparency by not only detecting AI use but also pinpointing the exact phrases or sections where AI content was used.
The company boasts an independently verified over 99% detection rate for AI-generated text.
The Business Insider authors stated that Copyleaks is the “most accurate... to detect wholly AI or human-generated content.”
The recognition comes as Copyleaks prepares to unveil new tools to address the evolving challenge of AI-generated imagery and video, following the introduction of models like OpenAI's Sora 2.
The Business Insider analysis was rigorous, involving 480 scans of 60 documents. These documents were designed to test the detectors under four different scenarios of AI involvement, ranging from entirely human-written to 100% AI-generated. The evaluation concluded that Copyleaks is the “most accurate... to detect wholly AI or human-generated content.”
A distinguishing feature that contributed to this high ranking is Copyleaks' superior transparency. Unlike competitors, the platform provides users with sentence-level detail, identifying the exact segments of text where AI assistance was utilized. This capability makes it the preferred tool for sectors where content integrity is non-negotiable, including businesses, education, publishing, and government agencies.
The leadership at Copyleaks stressed that in an era of rapid AI adoption, accuracy is paramount. Cofounder and CEO Alon Yamin articulated the company’s mission in the context of the evolving digital workflow.
He stated: “Accuracy has never been more critical. As AI becomes more deeply embedded in our workflows, from classrooms to corporate communications, people need tools they can trust to discern what’s original and what’s artificially generated. Our mission is to deliver that clarity and reliability, empowering organizations to uphold transparency and accountability across all digital content.”
At its technological foundation, the Copyleaks AI Detector leverages advanced machine learning and linguistic analysis to maintain an independently verified over 99% detection rate. It effectively identifies both unedited and modified AI text across more than 30 languages.

Looking ahead, the company is already preparing for the next wave of synthetic content, mentioning the emergence of high-fidelity video generation models like OpenAI's Sora 2. Copyleaks announced that it “will also be unveiling new tools to meet the moment as AI-generated imagery and video tools evolve rapidly,” underscoring its commitment to remaining at the forefront of content integrity across all media formats.
