Automate listing alerts that filter on what you actually care about
Every morning: nineteen new listings read in full, four duplicates collapsed across portals, twelve rejected with one-line reasons, and three shortlisted with the commute figure attached. Five minutes over coffee.
Portal alerts fire on price, bedrooms and an area polygon. Every real search lives in the criteria you can only see by reading the listing: the floor plan that wastes forty square feet on hallway, the "charming" that means dark, the service charge buried in paragraph nine.
So buyers and renters run a daily ritual across two or three portals plus a couple of agency sites, twenty to thirty minutes of opening the same listings the alerts already sent. A companion opens each new listing in your own browser, reads all of it (description, floor plan, charges, map) and scores it against criteria you wrote in plain language.
What can it filter on that the portals cannot?
Anything a careful reader could work out from the listing.
Commute time to a fixed address, checked on a map. Aspect, when photos or floor plans reveal it. Total cost including service charges and ground rent, not just the headline. Red-flag language: "in need of modernization", "chain", "no pets considered". Every verdict carries a reason and a link back to the listing.
The cross-portal layer matters too. The same flat listed by two agencies at two prices shows up as one entry with both links, which is exactly the discovery per-portal alerts never surface.
The two-bed hunt
Criteria: two-bed flat, top two floors preferred, no ground floor, outdoor space, under a fixed monthly total including charges, within twenty-five minutes of a named office by public transport, no "needs modernization". Sources: three portals and two local agencies’ own sites, swept each morning at eight.
A typical morning: nineteen new or changed listings across sources, four duplicates collapsed, twelve rejected with one-line reasons, three passed to the shortlist sheet with links, photos noted and the commute figure. Five minutes of review, and your reply to the agent goes out before the listing’s tenth inquiry arrives.
What is the sweep deciding for you?
Which four properties are worth a Saturday.
It reads each portal the way a signed-in house-hunter would, at that pace and inside each site’s terms, and where a portal prefers its own alerts the companion reads those emails and folds them into the same shortlist.
The viewing, the negotiation and the feeling in the hallway were always yours, and now you arrive at four addresses instead of forty. At client scale, see AI for real estate agents or AI for property managers; the underlying mechanism is watching sites for changes on a schedule.
