Moduui Gyeongmae (Everyone’s Auction) is a Korean auction information service operated by Jayjay Co., Ltd. It brings nationwide court auction and public-sale listings together, helping users explore properties and other assets, review sale dates and appraisal prices, and access rights-analysis information. Search categories include apartments, officetels, villas, commercial properties, land, detached homes, vehicles, and other assets, with map-based browsing and filters for regions and auction status.

The service also presents recent sale results, winning-bid rates, regional statistics, and market trends, alongside curated listings organized by themes such as redevelopment areas, newly registered items, and properties identified as having clean rights or potential discounts. Users can consult property reports, market-analysis articles, auction news, an introductory auction guide, and a glossary of auction terms. Expert consultations and customer support are available for questions about rights and property handover. The mobile app offers an AI assistant and alerts for newly listed properties. Auction information is compiled from public sources and is intended as a reference; users are advised to verify official court documents before bidding.
