renue Releases 'satei-ai,' an AI Service for Bulk Appraisal of Multiple Items from a Single Photo

renue Inc. (HQ: Minato-ku, Tokyo; CEO: Yusuke Yamamoto) has released 'satei-ai,' an AI service that performs bulk appraisals of multiple items from a single photo.

By automatically detecting multiple objects in a photo, the service provides comprehensive support, including product identification, basic counterfeit inspection, estimated resale prices based on public information, and the generation of pre-sale checklists.

Key Features

- AI-powered automated object detection: Eliminates the need to photograph items individually. The system identifies furniture, home appliances, bags, and books from a single room photo, reducing the time and effort spent on appraisals. - Estimated prices with market rationale: Displays price ranges for each item based on market circulation data (such as Mercari), including source URLs to save time on individual price research. - Counterfeit inspection and automated to-do lists: Automatically generates checklists for items such as branded goods (verifying logos, serial numbers, accessories) and smartphones (checking IMEI, device reset, functionality tests), streamlining the preparation process for resale.

About 'satei-ai'

'satei-ai' is an AI service that identifies items in room photos and provides estimated values based on market circulation prices from multiple channels like Mercari and Yahoo! Auctions.

For luxury goods, the AI organizes key inspection points—such as logos, engravings, serial numbers, and accessories—to provide appraisal results.

If diagnostic information is insufficient, the AI engages in a dialogue to increase accuracy by requesting additional photos or acquisition details. Required verification steps, such as 'photograph inside tag' or 'confirm serial number,' are generated as prioritized follow-up tasks.

Pre-sale checklists for smartphones, including IMEI verification (anti-theft/misuse check), device reset, and functionality tests, are also created based on the item, with results saved for future reference.

Market Background

As of 2024, the domestic Japanese reuse market reached 3.2628 trillion yen, a 4.5% year-on-year increase, continuing a 15-year growth streak since 2009. Within this, luxury goods grew by 15.7% to 423 billion yen, and mobile phones/smartphones grew by 22.4% to 105.9 billion yen.

The total market is projected to reach the 4 trillion yen scale by 2030, with the scope of transactions, including P2P, expanding annually.

Meanwhile, an estimated 90 trillion yen in 'hidden assets' (idle household items) remains dormant in homes, a supply potential roughly 30 times larger than the visible market. With declining birth rates and aging populations, needs for one-stop disposal—such as for end-of-life planning and moving—are increasing, raising the social demand for tools to immediately grasp the value of items at home.
