Where I live, where I go on living, where I want to live.
PLUS US is about the first decision two people make together: where to live. Two budgets, two commutes, two ideas of a good evening go on one table — and there is no single right answer, only a trade-off both people can live with. The public record behind every neighbourhood sits on the same screen as the answer.
WHAT YOU CAN DO
• Read the evidence without an account. Rent and purchase transactions from the Ministry of Land, Infrastructure and Transport; business, census and district indicators from Statistics Korea SGIS; Seoul cultural events; district news; and search interest by age band — every card carries the source it came from and sends you to the original.
• Open the map and move the weights. All 426 administrative neighbourhoods of Seoul on their real SGIS boundaries. Ten taste axes and three reality axes sit on sliders, and the shortlist repaints on the map as you move them — so you can see what the answer is hanging on, not only what it is.
• See what each condition takes away. A commute limit, a budget band or missing data each remove neighbourhoods, and the screen says which reason removed how many, so you know what to loosen.
• Open a candidate. Why it came up and what it costs, commute minutes to each of your anchor points, median deposit and monthly rent from real transactions, housing mix and floor area per person — and the apartment complexes those transactions came from, pinned on the map.
• Compare the 25 districts of Seoul on one basis. Median deposit, median monthly rent, median floor area, how many transactions closed, and the change from the previous contract month.
• Answer separately, in about five minutes. Six conditions — commute anchor, work style, commute tolerance, tenure, budget band, child plan — then eight scenes where you pick whichever one pulls at you.
• Invite your partner and put the two answers side by side. You each answer without seeing the other's, and the canvas shows what you already agree on and where you pull apart.
• Browse Discover — interviews, videos, a housing A to Z, and a shelf of official windows for public housing and tax programmes, which links you out rather than quoting terms at you.
• Follow the neighbourhoods you are watching, and keep them on your profile.
HOW THE RECOMMENDATION WORKS
A deterministic weighted sum over public data. No model inference. There is no overall score and no grade — what you get is a shortlist, the weight you gave each axis, and the trade-off spelled out in words.
Commute times are pre-built from the Seoul public-transit transfer-route service, so an axis with no data for you is left out and the screen says which one and why, instead of quietly counting it as zero.
WHAT WE ASK FOR, AND WHAT WE NEVER ASK FOR
Ranges only — an age band, the neighbourhood you live in, a tenure, a budget band. Never a street address, never a workplace address, never assets or debts, and no bank account is ever connected. We never ask your device where you are: you pick your neighbourhood yourself, from a list. You can delete your account and everything stored with it from inside the app.
Originals stay where they were published. We keep the title, the summary and the link, and send you to the source.
PLUS US also runs on the web at laboratory.stable.codes — the same screens, the same data.
