What you can design
A room designer with real furniture, free
A whole look in one tap
Cona AI, labeled Furnish (Beta) in the editor, places a curated set of real furniture in about a second. Sets exist for living rooms, bedrooms, dorms, studios and home offices.
Tune it, or undo it
Dials for amount, price, variety and space to move reshape the set. Furnish around my pieces keeps what you already placed, and one Undo clears the whole set.
Real pieces, real prices
Every piece in the catalog is a real product with its listed price, from IKEA, CB2, Herman Miller and others, and links to the retailer. Swap any piece and the room updates at true scale.
Floors, walls and light
Under Tools, pick a floor in wood, tile, stone, concrete or carpet, give the walls a solid color or a texture, and set the lights, so the room looks like a room and not a box.
Pick a style, or let Cona pick
In the Furnish panel, choose up to two styles, or leave the choice to Cona. Not quite it? Different pieces lays out a fresh set in the same room.
See it, share it, shop it
Look at the room from any angle in 3D and share it by link, account or not. The checkout groups your room by store, so the Amazon pieces go into one cart.
How it works
Design a room in three steps
Get your room in
Draw it to size, trace it from a photo or a PDF screenshot of the floor plan, or open a furnished room to try the designer first.
Tap Furnish and pick a look
Cona AI lays out a set of real furniture around your doors and windows. Turn the dials for price, amount and variety until it feels like yours.
Swap, restyle, then shop
Replace any piece, change the floor and the walls, and walk the room in 3D. Every piece links to its store with its listed price.
Real furniture
Why the pieces are real
A room designer full of made-up furniture shows you a nice picture and then leaves you to find something like it. Every piece in Cona is a real product, at its real size, with its listed price and a link to the store that sells it. When the room looks right on screen, you already know what it costs and where to buy it.
Because the sizes are real, the fit is real too. A sofa that crowds the window in Cona will crowd it at home, and a set that leaves a clear path in 3D leaves one in your room. If you want the long version of the process, read how to design a room in 3D.

FAQ
Frequently asked questions
Is there a free room designer online?+
Yes. Cona is a free 3D room designer that runs in your browser on a laptop or a phone. Designing and furnishing as many rooms as you like is free, with no credits and no watermarks.
How do I design my room in 3D for free?+
Get your room in first: draw it at its real size, or upload a photo of the floor plan. Then tap Furnish to start from a curated set, or drag in real pieces yourself, and look at the room from any angle in 3D.
Can AI design my room?+
Cona AI furnishes a room in one tap with a curated set of real furniture, laid out around your walls, doors and windows, and dials let you change price, amount and variety. It does not take a text prompt and does not make photoreal renders of your room.
Can I design my room from a photo of the room?+
Not from a photo of the room itself. You can upload a photo of the floor plan and Cona traces it, or sweep the room with your phone's camera and Cona rebuilds it in 3D. Building a scan into a room asks you to sign in.
Can I design a room with real furniture I can buy?+
Yes. Every catalog piece is a real product with its listed price, linking to its retailer, and the checkout groups your room by store. Some of those links earn Cona a commission; the price you pay is the same.
Do I need to sign up to design a room?+
No. You can design, furnish and share a room by link without an account. A free account carries your rooms between devices.
Can I design a kitchen or a bathroom?+
Cona AI does not furnish kitchens or bathrooms. You can still plan them by hand: Tools, then Kitchen or Bathroom, has built-in cabinets, appliances, vanities, showers and tubs to place to scale. These are planning pieces, not products for sale.
