The Evolution of SOIN-EST: AI Assistant for Welfare Equipment Selection

In an era where technology is increasingly being integrated into our daily lives, the domain of caregiving has not been left behind. CDI Co., Ltd., under the leadership of CEO Kuniyasu Hamaoka and based in Chuo, Tokyo, has taken a significant leap with its AI assistant, SOIN-EST. Designed to help users select the most suitable welfare equipment, SOIN-EST has recently undergone an upgrade to enhance its meeting minutes generation feature, with the update launched on October 27, 2025.

Overview of SOIN-EST’s Services

Approved for its innovative approach, SOIN-EST leverages a comprehensive database of welfare equipment to provide tailored recommendations based on users’ physical conditions. This AI-powered assistant not only proposes effective welfare equipment services that support independence but also predicts users' physical states one year ahead. The integration of a chat function allows users to engage with the system, ensuring responses are customized according to individual needs.

Key Features of the Recent Upgrade

With the latest improvements, SOIN-EST can now automatically generate drafts of meeting minutes and highlight the key points discussed during service team meetings. This feature acts as a game-changer in streamlining the workflow for caregivers, particularly busy care managers.

- Automatic Generation of Key Meeting Points: Users can record discussions during meetings, which SOIN-EST will transcribe and compile into a formal document. Additionally, previously recorded audio files can be uploaded, allowing for automatic draft creation based on recorded dialogue. This process ensures that welfare equipment consultants can quickly create preliminary minutes, enhancing the overall meeting efficiency.

- Supported Audio Formats: SOIN-EST accommodates various audio formats (MP3, M4A, MP4, WAV). Meeting attendees can utilize the recording features available on iPads and iPhones, with a maximum recording time of 60 minutes. Alternatively, audio recorded using any smartphone or IC recorder can also be utilized, making flexibility a cornerstone of this functionality.

- Manual Editing Options: After generating the meeting minutes, users can make manual adjustments through an intuitive interface. Once finalized, the documents can be exported in PDF format, ensuring accessibility and professionalism in documentation.
