The Core Challenge of Interior Design Decision-Making
Most clients struggle to visualise how chosen furniture will look in their real room. 2D brochures and mood boards are insufficient. AI interior tools and AR visualisation solve this by delivering photorealistic results or real-time overlays in the actual space.
AI Interior Design Tools: From Photo to Concept
RoomGPT (roomgpt.io): upload a real room photo, select a style (Modern, Scandinavian, Japanese, Minimalist, Tropical) — AI generates a redesigned room image in 10–30 seconds using Stable Diffusion + ControlNet. Free for the first 3 images; ~15 USD/month for unlimited.
Decor8.ai: higher image quality than RoomGPT with additional customisation — choose colours, materials, and furniture style. ~10–25 USD/month.
Midjourney + ControlNet (professional): for professional interior designers — ControlNet defines the room layout from a photo, Midjourney generates photorealistic renders with fine-grained style control.
Interior AI (interiorai.com): purpose-built for home interiors, supporting 40+ styles with 3D render output.
AR Interior Apps: See Furniture Before You Buy
IKEA Place: the best product-specific AR app — place IKEA furniture on your real floor via the phone camera. Scale accurate to ±1–2cm on iPhone 12 Pro+ (LiDAR). Best for customers who know they want IKEA.
Houzz: AR + social platform with products from multiple brands, not just IKEA. View in My Room places furniture on your actual floor at accurate scale on LiDAR devices; real user reviews aid decision-making.
Planner 5D: 2D floorplan + 3D interior design app — not just AR. Design the entire room in the app, then render in 3D to preview the result before hiring an interior contractor.
Autodesk Forma (formerly Spacemaker): professional-level — analyses sunlight, shadow, and noise in interior layouts before committing to a design.
Apple Vision Pro for Spatial Interior Review
Apple Vision Pro (visionOS) delivers the best interior review experience.
3D room scan: use an iPhone 15 Pro/16 Pro LiDAR scan to create a 3D model → import into Reality Composer Pro → display in Vision Pro at 1:1 scale.
Furniture placement in spatial: place virtual furniture at 1:1 scale in the real room through Vision Pro’s passthrough camera — walk around and view from any angle.
Material review: change furniture texture and colour in real time — see whether a grey or brown sofa works with the room’s actual hardwood floor.
Workflow: AI Design → AR Review → Purchase
Photograph the living room and kitchen with iPhone.
Upload to RoomGPT and experiment with 3–5 styles — choose a favourite.
Take the chosen style into Planner 5D to lay out furniture positions.
Search for real furniture in Houzz or IKEA that matches the style.
Use IKEA Place/Houzz AR to place actual furniture in the room before ordering.
(Optional) Use Vision Pro for a full spatial preview before committing.
