Draw the Floor Plan
Paint floors, walls, doors and furniture onto a grid, storey by storey. Stairs link levels wherever their footprints overlap, and exits are first-class — the simulation reads egress straight off what you drew.

How it works
2
Place Markers & Simulate
Set where the fire starts, where the occupants are, and where they must gather outside. Fire spreads by material, smoke drifts and climbs the stairwells, and everyone walks for the nearest way out.
3
Analyze the Outcome
Scrub the playback to see where people bunched up and when each storey filled with smoke, then have the AI write a safety assessment with findings and concrete changes to the plan.
Multi-storey by design
Up to twelve levels sharing one coordinate space, so a stair run on one storey lands exactly where it should on the next.
Smoke that behaves
Concentration spreads as a front rather than a blur, vents through open exits, and rises between storeys — it slows people down and it is what makes them notice the fire.
Extinguishers are a trade-off
An occupant may divert to fight an incipient fire instead of leaving. Sometimes that saves the building. Sometimes it costs them the exit — and the report says which.
Nothing is auto-applied
The AI report is advisory. It names cells and explains itself; every change to the plan stays yours to make.
