ON THE LISTING / 01
Read it on
the listing 
The website starts with an address. The extension stays with the listing—where its own facts and photos can add evidence a coordinate cannot carry.
SAME ENGINE · SAME LIMIT
It reads maps and listing evidence, not fate. It does not predict, inspect unseen interiors, or offer professional advice.
EVIDENCE FIELD / NOT A PROPERTY VERDICT
One listing. Two kinds of evidence.
A quiet record of what comes from public map geometry, what comes from the listing page, and what remains unknown. Confidence stays attached to the call.

What the site can put on record
The website is address-in, evidence-out. It reads a listing’s surroundings from public map data: road form, mapped water, nearby land uses, power lines, and other wider-setting cues. That is the right lens for a road’s approach, a curve, an open edge, or a pattern in the map around a property.
It is deliberately limited. Public maps can be incomplete; a feature that is not mapped is not proof that it is absent. They also do not reliably say where the actual front door is, what a threshold looks like, or how a listing presents its home. The website keeps those limits visible rather than filling them with certainty.

What changes on the listing page
The Chrome extension runs on Zillow, Redfin, and Realtor listing pages. It can carry the same map reading into the page, then weigh the listing’s own facts in context. A listed facing can be used as listing-provided data, rather than guessed only from the street. It is still a reported fact to check—not a compass measurement made by the extension.
It can also consider the entrance, 門面, when the listing supplies a useful exterior photo. This is a photo-only call: the map never knows the real door. If no relevant photo or listing detail is available, the extension does not invent an entrance reading. It does not see interiors that the listing does not show.
Its panel is bilingual, Chinese and English, and keeps the same calm order: the most important concern first, evidence named, confidence labelled, and unknowns left as unknowns. The result is a better visit checklist—not a promise about a home’s future.

Open the panel where the listing is
Install the companion for a confidence-labelled reading beside a supported listing. It is one more way to put observable context on the record before a visit.
