South Korean proptech leader ZIGBANG unveiled three AI-powered residential services at a real estate trend show, including a conversational AI broker and a jeonse fraud detection tool. The showcase, reported on July 1, 2026, demonstrates how AI is cutting the time and complexity of property transactions and construction feasibility analyses.
AI broker suggests homes through conversation
The new AI Broker service uses an AI agent that asks users about their budget, desired neighborhoods, and other conditions, then directly recommends matching properties. Users avoid the need to search listings or visit agencies. If no suitable property is found, the system suggests alternatives in nearby areas.
Real estate agents interested in adopting similar conversational tools may find the AI Learning Path for Real Estate Brokers helpful for understanding AI-driven lead generation and marketing.
Fraud diagnosis and contract safeguards
Another service, AI Guardian Diagnosis, evaluates the risk of jeonse fraud or rights disputes by analyzing an address before a contract is signed. The tool integrates public safety data to show crime history and the distribution of crime prevention facilities around the property, and it proposes customized special contract clauses to mitigate identified risks.
Subscription and construction analysis tools
ZIGBANG also introduced the Subscription Diagnosis Report, which calculates an individual's subscription points and provides eligibility and winning probability reports for 12 types of housing supply categories. By interpreting complex subscription rules, the AI helps users independently build their application strategies.
Separately, the AI-based platform Seoul Land Doctor demonstrated solutions for multi-family villa projects, focusing on Seoul's Gangnam and Seocho districts. The platform's proprietary AI cuts building scale reviews and feasibility analyses from weeks to 30 seconds. Visitors at the booth could input any Seoul address and receive simulated architectural designs and feasibility results within half a minute.
Seoul Land Doctor also offers an asset succession consulting program for individual owners, proposing real estate development business models and connecting users with tax accountants and lawyers. For corporate clients, it provides an integrated service where AI and experts jointly support everything from candidate site analysis to sales strategy design.
Why this matters for real estate and construction professionals
For professionals in real estate and construction, these demos signal a shift in how AI handles high-stakes property decisions. The reduction of feasibility studies from weeks to seconds, as shown by Seoul Land Doctor, can directly speed up project timelines. Meanwhile, AI-driven contract risk analysis addresses a persistent pain point in jeonse-heavy markets. These tools are part of a wider move toward AI for Real Estate & Construction that automates analysis and recommendation tasks once reliant on manual expertise.
