WhatOnSite shows where every piece of equipment is, when it needs a service and what went wrong last time — so your team spends minutes, not hours, and small problems never become expensive ones.
The problem we solve
Whoever manages large homes or commercial buildings meets the same problems again and again. The information exists — on paper plans, in spreadsheets, in someone's memory. It's just never there when you need it.
Buildings are full of hidden systems: leak sensors, fire detectors, network routers, stopcocks, manifolds and wiring. When something breaks, time goes on searching, studying drawings and calling previous contractors.
WhatOnSite keeps a digital map of the building. Find any equipment and see where it is, its photos, drawings and manuals — in a few clicks.
Dozens of systems, lots of equipment and many contractors. A service is easy to miss, a repeat visit costs money, and contractors change and don't always know the site.
The technician scans the QR code, gets everything they need and records the service on the spot. The history is saved to the cloud automatically — no separate logbooks, no reports to put together by hand.
Most expensive breakdowns start as something small — a temperature creeping up, a reading that drifts — that nobody noticed in time.
The building's digital passport is joined to your smart home system and sensors. They watch the equipment and flag anything outside its safe range before a small problem becomes a costly failure.
Sensor readings, service history and past faults pile up, but someone still has to read them and spot the pattern.
An AI that analyses sensor data, service history and faults — spotting equipment that is overheating or voltage that keeps dropping — and writes a report with recommendations. Today you can already ask the AI Manager about your building.
See it working
Everything below is recorded in WhatOnSite as it is today.
Type “smoke detector”. WhatOnSite opens the 360° photo of the room, turned to face it, with the marker glowing and the floor plan beside it.
Pin the fault on the 360° photo. Whoever fixes it sees the spot, the description, the photos and every update — no more “which one did you mean?”.
Every service has a date, a contractor and a status. Soon, scheduled and overdue are impossible to miss — and one click shows the equipment on site.
Temperatures, humidity and power from your sensors appear on the 360° photo. Set a safe range and get an alert before the freezer, server room or wine cooler goes wrong.
See behind the walls
Take a 360° photo during construction and another when it's finished. WhatOnSite keeps them on the same spot, so you can look at both side by side, any time.
Know exactly where the pipes and cables run — before anyone drills into a wall.
Saves time on every repair · prevents costly mistakes during renovations
On site, on the phone
A sticker on the boiler, the heat pump or the electrical panel opens its page: what it is, where it is, when it was serviced and who to call.
AI Manager
Type or speak a question. The answers come from your own building — its equipment, services, problems and documents — and can be read aloud.
How it works
The Guide walks you through every step. Start with one room — it pays back the first time you need to find something.
A PDF, a drawing or even a photo of the fire escape plan. Draw the rooms on it.
Walk the route with an Insta360 or your phone. Each photo lands on its spot on the plan.
Tap the boiler, the valve, the detector. Add manuals, service dates and the contractor.
Search, scan QR codes, get service reminders and live alerts. Ask the AI anything.
Our goal
Every building should have its own digital memory.
So any manager or technician can quickly understand what is in the building, where it is, how to look after it and what has happened to it before.
This isn't just somewhere to keep documents. It's one platform for the building's information, its maintenance, its contractors and — next — intelligent monitoring.
