Interior design online
Do the interior designof your own room, online.
Cona lets you do the interior design of your own room online, for free. Start from your real room: upload a photo, screenshot, render or sketch of the floor plan for the AI to trace, or draw the walls to size. Then design it in 3D: choose the floor and wall colours, place real furniture at its real size, or tap Furnish and let Cona AI lay out the whole room. Every piece has a real price and a link to its store, so the design you make is one you can actually buy and live in.

How it works
Interior design for your room, in three steps
Start from your real room
Upload an image of the floor plan for the AI to trace in about 20 seconds, or type the length of each wall.
Design it in 3D
Set the floor and wall colours, then place real furniture or tap Furnish for a complete layout by Cona AI, true to scale.
Refine and buy
Swap pieces, check gaps and look around from every angle. Buy what you love from the store that sells it.
Your room, not a mood board
From ideas to a room you can build
Ideas and inspiration show you other people's rooms. Interior design is making those ideas work in yours: the right sizes, a layout you can walk through, and pieces you can actually get. Cona does exactly that step, with your room at its real dimensions and real products in it.
