GenRoom vs Coohom: AI Photo vs 3D Modeling — Which Workflow Fits You?
Coohom asks you to build a 3D model of the room before you see any design. GenRoom asks you to upload a photo and click a style. Same goal — totally different workflows for totally different users. Here's a clean, honest breakdown.
Two products, two completely different workflows
Coohom is a cloud-based 3D interior design suite aimed at professional designers, retailers and furniture brands. You sketch a floor plan, place walls, doors and windows, then drag furniture from a catalog of 10M+ branded SKUs onto a 3D scene and hit Render. It's powerful — and it's a real piece of CAD software with a learning curve measured in hours, not minutes.
GenRoom goes the other direction. You upload a photo of an existing room — your living room, a client's kitchen, an empty Airbnb — pick a style, and our AI returns a photorealistic redesign in about 30 seconds. No 3D scene to build, no furniture to drag, no floor plan to draw. The model understands the room from the photo and rewrites the textures, materials, lighting and decor in place.
That single architectural difference shapes everything else. Coohom is best when you're creating a room that doesn't exist yet — new construction, empty units, retail catalog scenes, exact-dimension layouts for a furniture order. GenRoom is best when the room already exists and you want to see it differently — renovating an apartment, restyling a listing, showing a homeowner three options before they pick paint, generating quick concept frames on your phone in a meeting.
This page lays out the differences feature by feature so you can pick the right tool — or use both, since they don't really compete. Coohom for design, GenRoom for AI redesign.
GenRoom vs Coohom — feature comparison
Ten dimensions that actually matter when you're choosing a workflow. Honest answers, not marketing.
| GenRoom | Coohom | |

Workflow comparison
What you'll actually do, step by step, from opening the tool to having a usable image.
Upload a photo of the existing room
Any JPEG or PNG works — phone photo, listing photo, sketch, even a clean photo of an empty room. No measurements needed; the AI infers geometry from the image.
Pick a style and click Generate
Scandinavian, Japandi, mid-century, industrial loft, coastal, biophilic — over 200 curated styles, plus free-form prompt edits if you want something specific.
Get a photorealistic redesign in ~30 seconds
The AI rewrites materials, decor, lighting and furniture in place while keeping the room's structure (windows, walls, layout). Download, share, regenerate, or iterate.
Draw the floor plan in 2D
Use Coohom's plan editor to lay down walls, doors and windows with real dimensions. This typically takes 20–40 minutes for a single apartment.
Place furniture from the catalog
Drag SKUs from the 10M+ furniture library into the 3D scene. Adjust positioning, orientation and clearances by hand for each piece.
Apply materials and lighting
Pick floor textures, wall paints, ceiling materials. Set up light sources, exposure, sun direction. UV-tile any custom textures.
Queue a cloud render
Hit Render and wait 1–10 minutes for a high-quality PBR render of your scene. Re-iterate by going back to the 3D editor and tweaking.
When to choose GenRoom — and when to choose Coohom
When to choose GenRoom
- You're renovating an existing roomThe room already exists. You want to see it with different paint, new flooring, restyled furniture or a totally different style — without rebuilding it in 3D. Free to try, 6 credits with no signup needed.
- You're not a CAD userYou have no design or 3D modeling skills, no time to learn Coohom's editor, and you don't want a subscription locking you in. Pay-as-you-go credits, transparent per-image cost.
- You need quick previews — often from mobileStanding in a client's apartment, on a real estate visit, or sketching ideas on a Saturday morning. Upload from your phone, get a photoreal preview in 30 seconds.
- You want the latest generative AIGenRoom runs on continuously updated frontier image AI models, swapped in as soon as state-of-the-art improves. Coohom uses traditional 3D rendering — no generative AI in the loop, so styling options are catalog-bound.
When to choose Coohom
- You're designing for new constructionThe room doesn't exist yet — it's a floor plan, a unit being built, or a retail showroom layout. You need exact dimensions and a real 3D scene, not a photo redesign.
- You're sending the client to a furniture catalogCoohom is owned by the same group as Kujiale and is tightly integrated with furniture e-commerce — clients can click a sofa in the scene and go buy the exact SKU.
- You're a professional designer who already knows CADYou're comfortable with a multi-hour workflow, you want pixel-precise control over geometry, lighting and materials, and you bill for the time you spend designing.
- You need exact dimensions and a 2D floor planConstruction-grade output: dimensioned plans, elevations, accurate clearances, real material specs. GenRoom can't do this — it works from a photo, not from CAD.
Pricing: pay-as-you-go credits vs annual subscription
Both have a free tier — but they price very differently after that.
Buy a credit pack once and use it whenever. Every generation has a published, transparent credit cost. No annual lock-in, no surprises, no auto-renew.
- 6 free credits to start — no email, no card
- Transparent per-image cost shown before you generate
- Credits valid for 180 days from purchase
Free tier is limited (lower render resolution, watermarked exports, restricted catalog). Real usage requires a Pro plan billed annually, plus enterprise tiers for furniture brands and retailers.
- Signup required to access the editor at all
- Pro tier pushed via annual billing
- High-res / 4K renders gated behind paid plans

GenRoom vs Coohom — frequently asked questions
Quick honest answers to the six questions we get asked most often by people deciding between the two tools.
Still not sure which one fits?
Tell us about your project and we'll honestly say whether GenRoom or Coohom is the better fit — even if the answer is Coohom.
Ask us- Partially. GenRoom is an alternative if your goal is to redesign an existing room from a photo and you don't need a 3D editor, exact dimensions or a branded furniture catalog. If you need to design a new build from a floor plan with construction-grade outputs, Coohom is the better fit and GenRoom won't replace it. Many designers use both: Coohom for new builds and GenRoom for fast AI redesign previews of existing rooms.
- If you're a professional designer working with new construction or furniture brands, Coohom is genuinely worth it — the 10M+ SKU catalog and 2D/3D editor are best in class. If you're a homeowner renovating one apartment, a real estate agent restyling listings, or a designer doing quick concept previews, Coohom is overkill and the multi-hour workflow plus annual subscription become a burden. GenRoom is free to try with 6 credits and no signup, so you can find out which workflow fits you in under a minute.
- No. Coohom's defining feature is the 10M+ branded furniture catalog with click-to-buy integration — GenRoom generates furniture procedurally from a style and a photo, but it doesn't link to real SKUs you can purchase. If furniture e-commerce is the goal, Coohom wins. If photorealistic style previews are the goal, GenRoom wins on speed, photorealism and price.
- GenRoom is dramatically faster — about 30 seconds from photo upload to finished render, with no scene to build. Coohom's first render typically takes 1–3 hours total (drawing the floor plan, placing furniture, applying materials, then queuing a cloud render that itself runs 1–10 minutes). For iteration speed, GenRoom is in a different league.
- No. GenRoom gives you 6 free credits with no email and no credit card — you can generate your first redesign before creating an account. Coohom requires a signup before you can access the editor at all, even on the free tier. Transparent per-generation pricing on GenRoom means you always see the cost upfront, with no subscription required.
- Real generative AI. GenRoom is built on the latest generation of image AI models — the model sees your photo, understands the room's geometry and lighting, and generates a new photoreal version in the style you chose. We continuously swap in newer frontier models as they improve, so quality keeps going up without you doing anything. Coohom is traditional 3D rendering: PBR ray tracing applied to a hand-built scene with catalog furniture. Beautiful results, but bound by the catalog and the time you spend building the scene.
