Wellvill's Dialogue AI 'LIFE TALK ENGINE' Adopted by Second Life Partners' New Service 'Mimamori 365'

Wellvill Inc. (Headquarters: Bunkyo-ku, Tokyo; CEO: Tomoko Matsuda), a company dedicated to enriching lives through dialogue and providing the Japanese dialogue AI 'LIFE TALK ENGINE,' announces that its technology has been adopted by Second Life Partners Co., Ltd. (Headquarters: Suginami-ku, Tokyo; President & CEO: Masaaki Masuda) for their newly launched service 'Mimamori 365.'

This initiative enables natural, personalized conversations between users and AI avatars through the 'Mimamori 365' companion partner system.

Background of Adoption

In Japan, advancing aging has led to a growing number of elderly individuals living alone and facing social isolation due to physical distance from family—emerging as critical social issues. Meanwhile, traditional monitoring services have primarily focused on emergency alerts and sensor-based safety checks, with few offering a presence that accompanies users in daily life or someone they can casually consult.

To address these challenges, Second Life Partners has integrated Wellvill’s 'LIFE TALK ENGINE' into the 'companion partner' component of 'Mimamori 365.'

Wellvill has advanced research and development of dialogue AI for the elderly through pilot projects with senior care facilities, local governments, and medical institutions. The company’s expertise in understanding cognitive changes and building sustained conversational relationships has been highly recognized, leading to this adoption.

Role of 'LIFE TALK ENGINE'

'LIFE TALK ENGINE' serves as the core dialogue technology enabling natural interactions between users and AI avatars within 'Mimamori 365’s' 'companion partner' feature, supporting daily conversations and lifestyle assistance.

Users can engage in everyday conversations with the AI avatar via smartphone. The AI learns from conversation history and user preferences to deliver personalized, natural communication tailored to each individual.

Additionally, the system supports independent living by:

- Assessing psychological state through daily conversations
- Reminding users of medication schedules and medical appointments
- Conducting cognitive ability assessments every three months
- Reducing feelings of loneliness through continuous dialogue

Future Outlook

Wellvill will continue leveraging 'LIFE TALK ENGINE' to expand collaborations across elderly monitoring, caregiving, healthcare, and local government sectors. The company aims to realize a society where dialogue AI transcends being a mere conversational partner and becomes an essential supporter of individual health and daily life, expanding its service offerings accordingly.

About the Japanese Dialogue AI 'LIFE TALK ENGINE'

'LIFE TALK ENGINE' is an AI dialogue engine capable of interpreting ambiguous, non-grammatical Japanese expressions by analyzing context, enabling natural responses. It understands the meaning and emotional tone of human speech and leverages stored conversational history to generate contextually appropriate replies.

Unlike conventional chatbots, it can proactively initiate questions to guide conversations, eliminating the need for users to learn complex operations. This allows elderly individuals and non-native speakers to intuitively use the service through natural dialogue.
