NhaDat Radar is a "radar" that scans real estate news: it aggregates listings for sale and rent from various sources (Chợ Tốt, Mogi, Batdongsan, Guland, Facebook, Zalo) in one place, uses AI to standardize the data, and rates each listing. The problem solved: those searching for homes need to browse 5-7 pages, there are duplicate listings across different sites, inflated prices, and sold listings that are still posted. The Radar consolidates the entire market in one place, eliminates duplicate sources, automatically marks removed listings, and warns about listings that are priced inconsistently compared to the neighborhood. Main features: searching with a satellite map and filtering down to the district level; price trends by district; AI pricing based on actual listings in the area; exclusive listings from Facebook and Zalo not available on any other real estate site, the phone numbers of the posters are kept private to avoid spam from brokers; posting listings by messaging Zalo - sending a description along with photos results in the AI bot automatically extracting and posting within a minute, and editing listings is also done via chat; notifications of new listings matching demand via Zalo message or email. Who should use it: buyers or renters wanting to see the entire market in one place; property owners wanting to post listings quickly without worrying about exposing their phone numbers. How to get started: open nhadatradar.com in a browser to start using it immediately, with no installation required; if you want to post a listing, message Zalo for Radar. What sets it apart: major sites are for POSTING listings, Radar is for SEARCHING - consolidating the entire market including Facebook and Zalo listings that those other sites do not have, plus an AI layer for filtering, scoring, and pricing that works on the buyer's behalf.
