OnStay starts with evidence about one property, then asks its host for the practical guest-use knowledge that is still missing. The result is a concierge grounded in that home's sources and the host's own answers.
The host supplies the public listing and can add the property's direct site, welcome book, guest guide, manuals, PDFs, and other documents guests already use. OnStay preserves each source before studying them together.
A source can prove that an amenity exists without explaining where it is or how this property uses it. OnStay looks across the complete source bundle for useful relationships, omissions, and contradictions. A mention does not become a complete guest answer by itself.
The host conversation starts from evidence about that home. If the listing names a hair dryer but no source gives its location, the useful question is where guests can find it. A property without that amenity does not get the same question.
OnStay combines accepted source facts with the host's answers into the property's knowledge. The concierge becomes available when setup is complete. Later questions that remain uncertain, safety-sensitive, or dependent on human judgment return to the host with context.
Source omission: “Hair dryer” appears in the listing, with no storage location.
Host detail: “It is below the main bathroom sink.”
Guest answer: “The hair dryer is below the main bathroom sink.”

Guests open the property concierge from a QR code or shared link in a browser and can ask about parking, checkout, WiFi, or property amenities.
