Share and work together
Share room makes a link that opens in anyone's browser. Edit together lets someone change the room with you live.
Why a web platform
Everyone can open it, nobody has to install it
A room you design in Cona is a link, so a partner, roommate, landlord or client sees it in their own browser without an account or an app. When you want to decide together, Edit together puts you both in the same room at the same time.
Because it runs on the web, it needs an internet connection; the furniture, 3D models and AI load as you use them.
