AI room redesign generated with DecorAI in Japandi style

Steps (6)

1
Download DecorAI on your phone or open the web app
Install DecorAI free from the Apple App Store on iPhone or iPad, from Google Play on Android, or open the web app at app.decoraihome.com in any modern browser. No credit card is required to start.
2
Take a wide-angle photo of the room you want to redesign
Stand at one corner of the room and capture as much of the space as possible. Good light, a wide angle, and an eye-level perspective give the AI the most information to work with. Avoid extreme close-ups or photos taken in low light.
3
Open DecorAI and upload the photo
Tap the upload button and pick the photo from your camera roll, or take a new one inside the app. DecorAI accepts JPG, PNG, and HEIC formats.
4
Pick a design style from the library
Choose from 30+ styles: Modern, Scandinavian, Japandi, Bohemian, Industrial, Minimalist, Farmhouse, Coastal, Maximalist, Wabi-Sabi, Mid-Century Modern, Art Deco, and more. Each style has a defined palette, materials, and furniture vocabulary that the AI applies.
5
Tap generate and wait a few seconds
DecorAI reads your room's geometry, lighting, and key features, then generates a photorealistic redesign in the chosen style. Generation typically takes under a minute.
6
Regenerate variations or save your favorite
If the first result isn't quite right, tap regenerate for a new take in the same style. When you're happy, save the redesign to your account, share it as an image, or use it as a reference to plan a real-world refresh.

The whole process takes about two minutes once you have a photo ready. You can regenerate as many variations as you want — each regeneration produces a slightly different take on the chosen style.

If you want to compare multiple styles for the same room, generate the same photo in two or three different styles back to back. DecorAI keeps your generation history in your account so you can review them side by side later.

Tips

Wide-angle photos work better than tight close-ups
Daylight gives sharper, more realistic results than artificial light
Photos with less clutter generate more accurate redesigns
If a generation doesn't capture the style, regenerate — each pass is different
Save 2-3 of your favorite variations to compare against your real room later

Frequently asked

How long does it take to redesign a room with AI?

About two minutes once you have a photo of the room. The actual generation takes under a minute; the rest is uploading and picking a style.

Do I need to be good at design to use AI room redesign?

No. DecorAI is designed for non-designers. You just need a photo of your room and a sense of which styles you like. The AI handles everything else.

Can AI redesign my room from a photo I already have?

Yes. You can use any photo from your camera roll. The AI reads the geometry and lighting from the photo itself — you don't need to measure or annotate anything.

What's the best photo to use for AI room redesign?

A wide-angle photo taken at eye level, in good daylight, showing as much of the room as possible. Avoid extreme close-ups, dark photos, or shots with heavy obstructions in the foreground.

Can I redesign a room I'm renting?

Yes. AI redesigns are visualizations — they don't change anything in your real space. Many renters use DecorAI to test style ideas without making permanent changes.

Does AI room redesign cost money?

DecorAI is free to download and includes free generations to start. An optional premium subscription unlocks unlimited generations.
