About MUHAYU

MUHAYU is a specialized AI firm focused on automating evaluation-related work processes through natural language understanding (NLU) technology. Founded in July 2011 by CEO Shin Dong-ho, the company name draws inspiration from the Taoist concept of 'Muhayujihyang', signifying a natural, untroubled place. This philosophy underpins its mission to simplify work. Shin, who holds degrees in computer engineering and cognitive science from Seoul National University, leveraged his extensive background in search technology to address the challenges of information overload and plagiarism. This led to the creation of MUHAYU's flagship product, 'Copy Killer'.

The company operates on a Software-as-a-Service (SaaS) business model, providing its solutions primarily to other businesses and institutions. Its core offering, Copy Killer, is a plagiarism detection service that compares documents against a vast database of over 10 billion items to calculate a plagiarism score within a minute. This service is used by 96% of four-year universities in South Korea and over 3,400 organizations, including corporations and public institutions. Building on the rise of generative AI, MUHAYU launched 'GPT Killer' in June 2023, a service designed to detect text generated by AI models like GPT-4o with over 95% accuracy. This tool has been integrated into its other products to ensure content authenticity.

In 2018, MUHAYU expanded into the human resources market, leveraging its document analysis expertise. It now offers 'Prism', an AI-powered tool for screening application documents, and 'Monster', a conversational AI interview and competency assessment service. These HR solutions evaluate resumes and conduct initial interviews, providing tailored, in-depth questions to assess candidate suitability. After operating profitably without external funding for over a decade, MUHAYU secured its first investment in November 2023—a 15 billion KRW pre-IPO round from investors including DSC Investment, Devsisters Ventures, and STIC Ventures. The company is now planning for a KOSDAQ listing by 2026 to fuel further growth and international expansion, particularly into Asian markets like Japan and China.
