About
floorplan.chat is a spatial design agent. You describe a space in ordinary language, and it draws a floor plan you can keep working on.
How a design happens
- You describe the space, and you can attach a reference image.
- The agent proposes a plan. Nothing is drawn until you confirm it.
- The plan becomes a drawing you can look at in 2D and 3D.
- You change it by sending another message, or by editing the drawing yourself.
Editing by hand
On the drawing you can move walls, place doors, windows, and furniture, and adjust the layout directly. Those changes stay on the plan. They are not model messages, and on a paid plan they are not counted against your allowance.
Models
Each chat turn runs one model. The more expensive models are the frontier tier; the others are standard. Which is which follows the published prices, and the current split is on the pricing page.
New accounts use official credits. In Settings you can switch to your own OpenRouter key. Turns on your own key are billed by OpenRouter to you.
