How to Use DecorViz

Open the DecorViz app. You will see two panels: the left panel is where you upload your images and enter a prompt. The right panel is where your generated previews appear.

Step 1: Upload Your Room Photo

In the left panel, find the "Your Space" section. Click or drag a photo of the room where you want to place the furniture.

1

Take or choose a room photo

Use your phone or any camera to photograph the room. Aim for a photo that shows the area where you want the product placed, with some surrounding context like nearby walls, floor, and existing furniture.

Quick tip

You can drag and drop images directly onto the upload area, or click to browse your files. Photos from your phone camera work great.

Step 2: Upload Your Product Photo

Below the room photo, find the "Your Product" section. Upload a photo of the furniture you want to see in your room. This can be a photo you saved from a retailer's website, a screenshot from an online store, or a photo you took yourself.

2

Choose a clear product image

The best product photos show the entire item with good lighting. Photos from online stores usually work well. Avoid heavily cropped images or images that only show part of the product.

Step 3: Add a Prompt (Optional)

The "Prompt" field is optional but can help the AI place the product more accurately. Use it to describe where you want the product placed or to give extra context about the product.

3

Describe the placement

Write a short, natural description. For example: "Place the sofa against the back wall" or "Put the rug under the coffee table." Keep it simple and specific.

Example prompts

Sofa placement
"Place the gray sectional sofa against the left wall, facing the TV"
Rug placement
"Place the rug in the center of the living room, under the coffee table"
Lamp placement
"Place the floor lamp in the corner next to the armchair"
Dining table
"This is a round oak dining table for 4 people, place it in the center of the dining area"
When to use a prompt

A prompt is especially useful when the room has multiple possible placement spots, when the product could go on the floor or a wall, or when you want to describe the product in more detail (for example, "a velvet accent chair with gold legs").

Step 4: Generate Your Preview

4

Click "Generate Visualization"

Once your room photo and product photo are uploaded, click the "Generate Visualization" button. The AI will create your preview in about 30 seconds. The result will appear in the Results panel on the right side of the screen.

Each generation uses one credit. If you are not happy with the result, you can adjust your photos or prompt and try again.

Iterate freely

It is completely normal to try multiple versions. Keep the same room photo and swap out different products to compare, or adjust your prompt for better placement. Iteration is part of the process.

Tips for Best Results

The quality of your preview depends heavily on the photos you upload. Here are practical tips to get the most realistic results.

Room Photo Tips

Your room photo gives the AI context about your space: the walls, floor, lighting, and existing furniture. A good room photo leads to a more natural-looking result.

Do

  • Use natural lighting when possible
  • Show the floor and walls where the product will go
  • Include nearby existing furniture for context
  • Take the photo from a natural standing angle
  • Use a landscape orientation for wider rooms

Avoid

  • Very dark rooms with no visible detail
  • Extreme wide-angle or fisheye lens photos
  • Close-up shots that cut off the floor or walls
  • Blurry or motion-blurred images
  • Heavily filtered or edited photos
Best room photos

Stand at the opposite side of the room from where you want the product placed. Capture the full wall and floor area. Think of it like a real estate listing photo of that corner or wall.

Product Photo Tips

The product photo tells the AI what the furniture looks like. The more context the photo provides, the better the AI can integrate it into your room.

Do

  • Use a photo where the entire product is visible
  • Choose images with some perspective (slight angle)
  • Use well-lit product photos
  • Product photos from retailer websites usually work well
  • Include some background or floor for context

Avoid

  • Heavily cropped photos that cut off legs or edges
  • Pure white background cutouts with no context
  • Flat, straight-on photos paired with angled room shots
  • Collages or multiple products in one image
  • Very small or low-resolution images
Why perspective matters

A product photo taken at a slight angle gives the AI more depth information. This helps it blend the product into your room more naturally. Flat, head-on product shots combined with angled room shots can sometimes produce less convincing results.

Prompt Tips

The prompt is your way to guide the AI. It is optional, but a good prompt can noticeably improve placement accuracy.

Prompt Type Example When to Use
Placement "Place it against the right wall" Room has multiple possible spots
Description "A navy blue velvet sofa with wooden legs" Product colors are hard to tell from the photo
Combination "Place this round oak dining table in the center of the room" You want both description and placement
Context "A 6x9 feet handwoven wool area rug" Product details are not obvious from the image
Keep it simple

Short, clear prompts work best. You do not need to write a paragraph. One or two sentences describing the product and where it should go is all the AI needs.

Managing Your Results

All your generated previews appear in the Results panel on the right side of the app. Here is what you can do with them.

View full screen

Click on any generated image to open it in full-screen view. This lets you examine the details up close.

Download your preview

Click the download button on any result to save it to your device. Share it with family or friends to get their opinion before buying.

Delete a result

Click the delete button to remove any preview you no longer need. This helps keep your results panel clean.

Compare products side by side

Generate previews of different products in the same room and scroll through your results to compare them. This is a great way to narrow down your choices before making a purchase.

Understanding Credits

Each generated preview uses one credit. Your remaining credits are shown in the top right corner of the app. Here is how the credit system works.

Credit Type How You Get Them Details
Subscription Credits Monthly subscription (Pro, Ultra) Refresh each billing cycle. Used first.
One-Time Credits Buy a credit pack Do not expire. Used after subscription credits.
Bonus Credits Referrals, promotions Free credits. Used last.

When you generate a preview, the system uses credits in this order: Subscription first, then One-Time, then Bonus.

Running low on credits?

When you run out of credits, you will see options to upgrade your plan, buy a one-time credit pack, or invite a friend to earn bonus credits. Visit the Pricing page to see all available plans.

Troubleshooting

If your preview does not look quite right, here are common issues and how to fix them.

?

Product looks "pasted on" instead of natural

This usually happens when the product photo is a flat cutout on a pure white background. Try using a product photo that includes some floor, shadow, or background context. Adding a prompt that describes the product also helps.

?

Product placed in the wrong spot

If the room has multiple open areas, the AI might pick a different spot than you intended. Add a prompt that specifies placement, for example: "Place the rug under the coffee table" or "Put the lamp in the right corner."

?

Preview looks too dark or too bright

The AI tries to match the lighting in your room photo. If your room photo is very dark or has strong backlighting, the preview may reflect that. Try retaking the room photo with more balanced lighting, ideally during daylight.

?

Product proportions look off

This can happen when the product photo has a very different perspective angle than the room photo. Try a product image taken from a similar angle. If the product image is straight-on but the room is photographed from an angle, the blend will be less natural.

?

Generation failed or stuck loading

Occasionally a generation may fail due to server load. If this happens, your credit is automatically refunded. Simply try again. If the issue persists, make sure your images are under 5MB each and in JPG, PNG, or WebP format.

Frequently Asked Questions

What types of furniture can I visualize?

DecorViz works with sofas, rugs, beds, dining tables, coffee tables, TV stands, accent chairs, lamps, shelves, and more. Any furniture or decor product that you have a photo of can be visualized in your room.

How long does it take to generate a preview?

Each preview takes about 30 seconds to generate. You will see a loading indicator while the AI creates your visualization.

Can I try different products in the same room?

Yes. Keep your room photo uploaded and swap out the product photo as many times as you want. Each generation uses one credit.

What if my generation looks wrong?

Try adjusting your prompt, using a clearer product photo, or retaking your room photo with better lighting. Most issues come from input image quality. If a generation clearly fails (obvious wrong placement, floating objects, severe distortion), the system will automatically refund your credit.

Are my room photos private?

Yes. Your room photos and generated previews are private to your account. They are not shared with anyone, including furniture retailers who use DecorViz Storefront on their websites.

Can I use DecorViz on my phone?

Yes. DecorViz works in your mobile browser. You can take a photo of your room and upload it directly. No app download needed.

Does DecorViz guarantee the product will look exactly like the preview?

DecorViz generates realistic visual previews to help you make more informed decisions. Previews are designed to be believable and helpful, but lighting conditions, screen colors, and other factors mean the real-world result may vary slightly.

What image formats are supported?

JPG, PNG, and WebP files up to 5MB each. Photos taken directly from your phone camera work perfectly.
