Emerging Role of Generative AI from a Genealogical Perspective in Exploring Information about Surnames

In recent years, generative AI (GenAI) tools such as ChatGPT, Copilot, and Gemini have gained widespread popularity. These technologies are still under active development, with their functionalities and performance evolving rapidly. GenAIs are not only used to generate textual responses based on user prompts, but also to produce images, videos, software code, and other forms of content. Their applications are expanding across various domains and increasingly influencing multiple aspects of social life. A notable advancement in the past six months is the integration of real-time search capabilities into GenAI platforms. This study conducted a comparative analysis in the field of genealogy, focusing on how GenAI tools such as ChatGPT, Copilot, and Gemini respond to queries regarding Sato, the most common surname in Japan. The investigation examined differences in output quality and content across platforms. Additionally, the study explored the limitations of current GenAI tools in terms of their search scope and proposed guidelines for their appropriate use in genealogical research. Recommendations were provided for future applications of GenAI in this domain, emphasizing the importance of tool selection and multilingual inquiry strategies.
