Interior Design Software
Interior Design Software That Starts From a Room That Fits
Mood boards are easy; the hard part is knowing the sofa fits, the rug reaches and the paint works with the floor. RoomSketch3D starts with a plan drawn to scale, then lets you style it — real paint colors, real wood, stone and fabric textures — and see it in 3D or as a photoreal render before you buy a single thing.

Paint every wall with a real color
Choose from 10,000+ real colors from Behr, Benjamin Moore and Sherwin-Williams — by name or number — and paint one wall, a whole room or every wall on a floor, inside and outside faces separately. The 3D view shows the color in the room with its floor and furniture, not on a chip.
Wall paints
Floors and fabrics with real texture
Pick flooring room by room — hardwood with the plank width and length you want, tile, stone or carpet — and upholstery in velvet, linen, bouclé or leather. 40+ photo textures show the actual grain and weave in 3D, and a tile layout planner shows where cut tiles fall and how many boxes to buy.
Real textures
16 styles, or describe your own
When the room is laid out, open AI Render Studio, frame the view, and pick a style — Scandinavian, modern farmhouse, Japandi, mid-century and more — or type exactly what you want. In about 15 seconds you get a photorealistic picture of your room, built on your real layout.
Renders are optional: 5 are free, then one-time credit packs that never expire.
AI Render Studio
The same room, five ways
These are five renders of one kitchen designed in the app — the same cabinets, island and layout, styled differently. It's the quickest way to decide on a direction before you choose a single finish.

- Exports plans and pictures to share with a designer or contractor

- Include AI renders without limit: 5 are free, then optional credit packs

The 3:25 demo builds a two-story home from a blank page. It starts at 2:46, “AI photorealistic renders” — scrub back to watch the whole build.
Interior Design Software questions
Straight answers, including the limits
Is RoomSketch3D interior design software or a floor planner?
Both. It starts as a floor planner — rooms drawn to scale, furniture at true size — and adds the interior design layer on top: paint, flooring, fabrics, 3D, and optional photoreal renders. The plan is why the styling holds up when you buy.
Can I use real paint colors?
Yes — 10,000+ colors from Behr, Benjamin Moore and Sherwin-Williams, applied to one wall, a room or a whole floor and shown in 3D.
How do AI renders work and what do they cost?
Frame a 3D view, choose one of 16 styles or describe your own, and get a photorealistic picture in about 15 seconds. 5 renders are free; after that you buy one-time credit packs that never expire. The rest of the app is a single $19.99 purchase.
Is it for professional interior designers?
It works well for mocking up rooms quickly and showing a client a scaled plan, 3D views and renders. It is built for speed and clarity rather than full construction documentation.
