Relumi - AI photo interior redesign that keeps your structure intact

What is Relumi

You've been there. You upload a photo of your living room to one of those AI redesign tools, type "modern farmhouse," and hit generate. What comes back looks stunning — until you look closer. The window that used to be on the left wall is now floating over the sofa. The kitchen island has somehow grown two feet. The room outline itself is subtly reshaped, and suddenly that beautiful preview has nothing to do with the room you actually live in.

That's the core frustration with most AI interior design tools: they produce gorgeous renders that are architecturally impossible. And when you're making real renovation decisions — picking cabinet finishes, choosing paint colors, deciding whether that new floor will actually work — a preview that can't be trusted is worse than no preview at all.

Relumi takes a fundamentally different approach. It's a photo-based interior redesign tool that keeps walls, windows, and the room outline exactly where they are, while redesigning the elements you actually want to change: cabinets, paint, floors, and furniture. You upload a photo, describe the look you're after, and get a realistic preview in minutes — one that you can actually plan around.

The workflow is refreshingly simple:

1. Upload a photo of the room you want to redesign.

2. Describe the look you want — new cabinets, a paint color, different flooring, updated furniture.

3. Preview a realistic redesign, with walls and windows preserved in their original positions.

And here's the key insight: structure preservation isn't a limitation — it's a feature. It's the default behavior, so you don't have to babysit the tool to keep your layout intact. If you do want a layout change, you can still request it explicitly through your prompt. But by default, the rooms you redesign stay true to their real proportions.

The best part? You don't need a credit card to try it. Relumi gives you two free tries — you can generate your first result without even creating an account. Sign in to download the result and get one more free generation. Before you spend a cent on an AI design tool, you can see exactly what it does with your own room.

Why Structure Preservation Matters More Than You Think

At first glance, "it keeps your walls where they are" might not sound like a headline feature. But for anyone planning an actual renovation, structure preservation is the difference between a pretty picture and a trustworthy planning tool.

Think about what you need from a redesign preview. You need to know whether that new kitchen island will leave enough walking space. You need to see how new cabinets will work with the existing window placement and natural light. You need to judge whether a floor color works with the room's proportions. None of that is possible if the tool quietly shifts your window three feet to the right or widens the room by a foot.

When walls, windows, and the room outline stay anchored to their real positions, every redesign you generate is comparable. You can flip between different cabinet styles and know that the differences you're seeing are real styling differences — not artifacts of a tool that reshuffled the geometry between generations. That's what makes Relumi's previews genuinely useful for measurements, furniture fit, and sightlines.

The default behavior is simple: structure is preserved automatically. You don't need to write a careful prompt begging the tool to keep your layout intact. It just does. And it's worth taking a moment to appreciate how different this is from the output of many AI rendering tools, which produce renders that are beautiful precisely because the AI took creative license with your actual room — deceiving your eye in the process.

Now, some creators worry that structure preservation limits what they can do. It doesn't. If you want to knock down a wall, open up the floor plan, or reposition the kitchen island, you can say so in your prompt — and Relumi will accommodate a layout change. The difference is that the change is your decision, not the tool's quiet creative choice.

Who Is Using Relumi

Relumi isn't a one-size-fits-one tool. Different people hit the same wall — "I need to see what this room could look like, without it becoming an entirely different room" — and Relumi answers it in slightly different ways.

Scenario 1 — The homeowner planning a kitchen remodel. You've been staring at the same cabinets for a decade. You know you want a change, but you don't know which change. With Relumi, you upload a photo of your actual kitchen, describe different cabinet looks, and preview each option against your real walls and windows. No more guessing how dark green lowers will read against that south-facing window.

Scenario 2 — The DIY renovator repainting rooms. Paint is the highest-impact, lowest-cost renovation you can do — but only if you get the color right. Window positions matter enormously for how a paint color reads at different times of day. With Relumi, wall paint previews stay accurate because the window geometry doesn't shift. You've tried paint swatches; now you can try a whole wall.

Scenario 3 — The real estate agent or landlord staging a property. When you're marketing a space, buyers need to imagine themselves in it. Staging multiple furniture arrangements of the same actual room becomes effortless. Buyers see the genuine room outline with different furniture and decor — not an idealized rendering that doesn't match the walkthrough.

Scenario 4 — The interior designer presenting options to clients. Client communication is where projects live or die. Fast, credible before/after visuals help clients understand what you're proposing before any construction begins. Relumi lets you generate multiple looks of the same room quickly, keeping the conversation focused on design choices rather than interpretation gaps.

Scenario 5 — The renovation contractor estimating scope. Before work begins, aligning client expectations is half the battle. Quick visual previews of the end result help clients see what they're approving, reducing scope-creep surprises and mid-project changes.

One note on licensing: if you're redesigning rooms for a client or using the output for business purposes, keep in mind that free tries are for personal use only. Pack purchases and memberships include commercial use, so your professional projects stay fully licensed.

Pricing Plans That Fit Your Project

Relumi uses a straightforward, credit-based pricing model. Here's the simple economics: one generate = one credit = one returned image. Downloads are always free, and if a generation fails, you don't lose a credit. No surprise charges.

Let's start with the two membership options — designed for people redesigning multiple rooms over time.

Yearly — $49/year: 50 generates, 5 looks at once, 20% off credit packs, valid for a year.

Lifetime — $129 once: 180 generates, 10 looks at once, 30% off credit packs, valid forever. This is the plan labeled "Best value" on the site — and it's easy to see why. One payment, no renewal, and the highest per-generate value on the platform.

For anyone who wants to buy generates a la carte, credit packs are the way to go. They export at up to 2K resolution, stay valid for 3 months, and let you run 3 looks at once:

The Starter pack is described on the site as "a few more looks after the free tries." The "Most people start here" pack is "the usual pack for one real remodel." And the Remodel pack is "for a bigger project across more rooms."

On the resolution front: free generations run at 1K resolution by default, which is plenty for evaluating a look. 2K and 4K unlocks come with credit packs and Lifetime membership — essential if you want crisp, detail-rich output for presentations or client work.

Cost-per-generate is where the economics get compelling. Packs range from $0.45 down to $0.32 per generation, and members get an additional 20–30% off on top of that. When you're generating 20–50 previews across a remodel, that compounds into meaningful savings — versus paying per-render on other tools with unpredictable pricing.

Getting Started with Relumi

Getting your first redesign from Relumi takes minutes, not hours. Here's the fastest path from curiosity to a rendered preview of your own room.

Step 0 — See what's possible first. Before you upload your own photo, visit relumi.app and load an example room card. The site provides example room cards that load directly into the generator, so you can watch a full redesign happen before you invest your own photo. These are examples only — not your room — but they show you instantly what the tool can do.

Step 1 — Upload a photo of the room you want to redesign. A clear, well-lit photo of the room gives the best results. The more of the room you capture — walls, floor, windows — the more Relumi has to work with while preserving structure.

Step 2 — Describe the look you want. This is where you name the changes: new cabinets, a paint color, different flooring, updated furniture. The more specific you are, the better the output.

Step 3 — Generate once without an account. Yes, you read that right. Relumi lets you generate your first result without even signing up. See the result, evaluate whether the tool works the way you need it to.

Step 4 — Sign in to download and get a second free generate. Once you sign in, you can download your result and receive one more free 1K generation. Both free tries are kept for 1 week, run one at a time, export at 1K resolution, and are for personal use only.

A useful learning point for your first generations: structure is preserved by default. If you want a different layout — moving the kitchen island, opening up the floor plan — say so explicitly in your prompt. Otherwise, the tool assumes you want the room you have, redesigned.
