Free interior design
Interior design,free from the first click.
Cona is free interior design for the room you live in. Draw your room to size or upload a photo, render or sketch of the floor plan, and the AI traces it in about 20 seconds. Then furnish it in 3D with real furniture, or tap Furnish and let Cona AI do it for you. There are no credits to buy, no watermarks and no locked features behind a trial: the whole design is free, and you can start without signing up.

How it works
Free interior design in three steps
Put your room in
Type the wall lengths, or upload an image of the floor plan and let the AI trace the walls, doors and windows for free.
Furnish it
Add real furniture from the catalog at its real size, or tap Furnish for a full set from Cona AI. Both are free.
Look, share, buy
Walk around the room in 3D, send a link to anyone, and buy only the pieces you want, straight from their stores.
What free means here
Free means the whole design, not a trial
Many interior design apps call themselves free, then charge to resize furniture, upload a plan, export or run the AI. In Cona, drawing, the AI trace, Furnish, the 3D view and sharing a link are free, with no credits that run out.
A free account is only asked for when you want to keep a design across devices, build a phone scan into a room, invite someone to edit with you, or make a photoreal image with Imagine.
