## Official Release of LINE Extension Service "Erupo" | Mansion Research Co., Ltd.

Mansion Research Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; CEO: Tsutomu Yamada) is pleased to announce the official release of "Erupo," a LINE extension service specifically designed for real estate companies.

Official Website: https://erupo.jp/

"Erupo" is a service that leverages LINE, a tool commonly used in real estate sales, to streamline customer interaction, lead follow-up, and response management.

By using AI to automatically organize and summarize LINE conversations, the service reduces the workload of sales representatives while supporting improved communication quality with customers.

### Development Background

In recent years, the use of LINE for customer interaction has become common in the real estate industry. However, several challenges have emerged in the field:

- Difficulty in keeping track of specific customer requests as the number of clients increases.
- Overlooking important information due to long message threads.
- Lack of company-wide visibility when staff use personal accounts.
- Difficulty in noticing early signs of complaints.

"Erupo" was developed with the concept that "customer information and interaction status are naturally organized just by communicating on LINE."

### Main Features of "Erupo"

**1. AI-Powered Automatic Summarization of LINE Chats**
AI automatically summarizes the content of LINE talks with customers. This helps organize what the customer wants and their current status, preventing missed follow-ups or misunderstandings. Summaries are tailored to the transaction type (e.g., buying, selling, or renting), making lead management and project tracking smoother.

**2. Professional Interaction via Official LINE Accounts**
Consumers often feel uneasy about adding a sales rep's personal LINE account. With "Erupo," interactions happen through an Official LINE account, maintaining corporate trust while allowing for flexible communication from individual staff. This also allows the company to monitor interaction history, eliminating the issue of siloed information.

**3. Early Detection of Complaint Risks**
The system detects communication patterns that could lead to complaints. Managers can grasp the situation before problems escalate, allowing for early follow-up and quality improvement.

**4. Simple Design for Field Use**
The UI/UX is designed specifically for real estate operations, making it easy to adopt even for those unfamiliar with IT tools. Since it is based on daily-use LINE, it integrates easily into workflows.

### Future Outlook

Mansion Research will continue to strengthen its support for sales and DX by utilizing its expertise and big data in the real estate industry. Future plans include integrating "Erupo" with existing services to further support operational efficiency and customer experience.
