Everything runs in your browser. Nothing you build is sent anywhere.
Not a dashboard of what happened. A place to ask what would happen, to see the whole world while you ask it, and to read the chain of reasoning that produced the answer.
A tariff, an export control, a carbon price or a migration rule does not stop at the border it was written for. The engine carries it through trade, prices, currencies, employment and alignment, and shows you who absorbed it.
Concentration is easy to see and hard to price. Put the shock in, run it against the baseline on the same seed, and read the difference as the shock rather than the noise.
Put the chokepoints, the fab clusters and the trade flow on the map at once and the shape of the problem is visible before you run anything. Then close one and see how far the effect travels.
Energy dependence, oil production, renewable share and the energy flow are all layers. A supply lever moves the price, the price moves inflation, and inflation moves rates, currencies and debt service, which is where most of the damage actually lands.
Shift the policy rule and hold it. Debt service, currencies, investment and unemployment carry the weight in different proportions by country, and the risk premium does the rest.
Water stress, food self sufficiency, stability and emigration pressure sit beside the live feed of emergencies currently marked ongoing. The map shows both at once, and says which is observed and which is modelled.
Warming, water stress and a carbon price are levers. Emissions, renewable share, agriculture, inflation and competitiveness all move, and not in the same direction for everyone.
Births per woman, median age, urbanisation and net migration are layers you can watch across the horizon. A fertility policy shows nothing for a decade and then shows everything, which is the argument for a long run.
Every headline number is built as a sum of named terms, so the interface and the arithmetic agree exactly. You can open growth, find the term, and argue with the coefficient.
Every country row carries a provenance mark, and every sourced figure carries the year it came from. Nothing on the screen is presented as measured when it was patterned.
The globe turns, the flows move, the timeline plays, and the layers go on and off in front of the room. Then somebody asks what if, you type it, and two seconds later there is an answer with a range on it.
No account, no credits, no queue. Open it, write a sentence, and see what a coupled model of the planet does with it. That is a perfectly good reason.
None of these jobs wants a single number. They want the shape of a problem, the direction and rough size of an effect, the consequences nobody named, and the assumptions the view depends on. That is what a few hundred futures give you and a forecast does not.
If a run comes back with a wide spread, that is the answer. Narrowing it would be a decision about presentation rather than about the world.
Write one sentence about something you already have a view on, and see whether the model agrees with you.
