Recently, a startup company named IGSA, incubated by the Matsuo Laboratory at the University of Tokyo, announced the launch of a brain health management service for elderly people aged 50 to 70, called "Chat Chat."
The service aims to help users identify changes in cognitive functions such as mild cognitive impairment through simple voice conversations with an artificial intelligence. Users only need to add the official account "Chat Chat" on the social software LINE to start using it easily, without needing to download any additional applications.

This service is very easy to use. Under the guidance of the system, users will have a two-minute conversation with the AI. The topics of the conversation include "childhood memories" or "recent events," and users can freely express themselves according to their own wishes. The AI will assess the user's cognitive state by analyzing the user's voice characteristics (such as speech rate, pauses, and tone) and language characteristics (such as vocabulary and grammar), and finally provide the assessment results through LINE, classifying them into four levels A to D.
If users need a more detailed check, the system also provides a 15-minute in-depth assessment. At this stage, the AI will give advice on improving lifestyle based on the initial analysis results. After the assessment, users will receive recommendations, including brain-boosting exercises and local health activities, which allow users to directly sign up online.
IGSA emphasizes that unlike traditional testing methods that rely on arithmetic or memory questions, "Chat Chat" conducts health assessments through natural conversations, significantly reducing the psychological burden on the elderly. The early public version will last about a month, allowing users to experience it for free during this period. The official version will cost 1500 yen per year (approximately 73 Chinese yuan), and users can take up to three tests.
In addition, IGSA plans to include this service in local government-led care prevention programs. The CEO, Shoichiro Matsushima, said: "We hope that brain health testing can be as simple and easy as weighing yourself."
