Interior design AI software: how Formas compares in 2026

Formas is interior design AI software for designers, students and real estate teams who need to take a room from first idea to client presentation. You can start with a room photo, a sketch, a floor plan image or a model export, then produce renders, material moodboards, panoramas and concept video in one workspace. Furniture and finishes are costly to change once ordered, so the right software lets you show real options before anyone spends money. This guide compares Formas with the main options by the task in front of you, then runs a full project in Formas from moodboard to client delivery, with a reason for each tool.

Formas keeps plenty open for you to try: free templates in Drawing Studio and Style Transfer, and a fresh set of free credits each month. Open Formas Studio with one living room photo and a finish you are considering.

Interior design AI software compared

Start with what you have and what you need to hand over.

Formas belongs to a different group from most of this list. A photo app answers "what could this room look like in different styles?" Formas also helps you answer "which floor, which sofa and which palette should we present on Thursday?" Human design services such as Decorilla, which pairs design consultations with a shoppable product list, sit outside this table, since a designer does the work for you.

What AI tools for interior design actually do

AI applications turn photographs into realistic room visualizations. AI design tools also generate visual concepts and mood boards from text prompts or sketches, assist with space planning and furniture arrangements, and recommend complementary colors and materials. Some analyze room dimensions to suggest furniture layouts, catch dimensional mismatches before ordering, match furniture in an image to supplier catalogs, simulate natural sunlight patterns and acoustic performance, or estimate costs to help with budget control. Published comparisons of AI interior design tools put their accuracy on room proportions at around 80 to 85%, which is a good reason to measure before anyone orders. Most AI room design apps focus on a single photo: you upload a photo, pick from room types and a design style, and get new interior images back. That suits casual exploration, such as furnishing a first apartment or finding new ideas for home decor before spending money.

Professional interior design software has to do more. A designer works through programming, schematic design and design development, then specifies and procures FF&E. Across those stages you have to hold a concept across several rooms, change specific elements without disturbing the rest, and explain each decision to a client. Formas is strongest at the concept and presentation end of that. Keep your FF&E schedule, specifications and orders in the system you use for them, since Formas's asset records are estimates.

Key features of Formas for interior design, in project order

The easiest way to see these features is on one project. Picture a two-bedroom show apartment for a real estate agent. The living room is plain, the brief asks for warm modern style, and the agent wants one look across the living room, both bedrooms and the kitchen before the launch brochure goes out. Here is how to practice it, in the order the decisions come up.

1. Mood boards first, so the look is agreed before any room

Start with the board, because the agent can approve a palette in one conversation, and every later render inherits that decision. Formas documents this sequence in its moodboard to renders workflow, where an Art Deco board leads to a hotel bedroom, bathroom, corridor and lobby.

You have two ways in. Compose on the Freeform canvas when you already hold the materials: a stone sample, a timber sample and one inspiration image, plus swatches pulled from your own folders with Material Snapshot, as shown in the August workshop. Use Drawing Studio when you want a designed material board from an interior image, starting from a free template. The material moodboard guide has the details.

2. A custom drawing style as your style library

Since the apartment needs one look in several rooms, build a custom style now. Describe the style, then upload your references; flat-lay, top-down moodboards read most easily. Set Layer 1 for structure, Layer 2 for finish, and rules such as no text and no invented elements. Choose Draft the recipe, drop in an interior and choose Test style. Then refine by prompt or by editing the recipe, which can be saved as versions.

Publish it as Private, since this is a client's scheme. Under MY STYLES, keep the palette consistent, so stone stays the same stone in every room. Choose a test quality first and a higher one for what you present, then pick Pass 1 or Pass 2 if the interface offers them. Over time these styles become a personal style library, and Style Memory across projects is on Pro and Pro Plus. The Drawing Styles section of the July workshop shows recipes being tested.

3. The living room render, in Design Chat or Freeform

Move from the moodboard to the room with a spatial prompt: "warm modern living room, stone feature wall, timber joinery, keep window positions." Upload the room photo, and test in Draft quality.

Which surface should you use? Design Chat suits exploring in words, with persistent project chats, model switching and multi-image generation, and it combines with Notes for spatial instructions. Freeform suits working with references laid out, where Model Selection lets you try one or several models at once. Start in Chat if the brief is still loose, and in Freeform if the agent has already chosen the materials. Behind both, Formas orchestrates 60+ models and brings in improvements as those models get better, so you can leave the choice to automated orchestration or pick models yourself.

4. Smart Notes for more control over specific elements

Once the room is close, stop prompting the whole image. Add a Smart Note, point its arrow at the wall, attach the stone sample and write the instruction for that area. Add a second note for the joinery. Most clients find "do you prefer this floor?" easier to answer than "what do you think?", and you can compare each version of the same room in the left history panel. Check the window edges against the original photo each time, since the rest of the image can change too.

5. Deconstruct and Assets for the empty rooms

The bedrooms are bare or have leftover furniture, so Deconstruct gives you an unfurnished room view plus the extracted furniture and objects. Check it closely, because extraction can reconstruct hidden parts and alter details. The Formas empty room guide suggests stating what stays, such as room boundaries, windows and entrances, before the first layout.

Then add furniture from Assets, where a curated Interior Design Assets library covers furniture, fixtures and decor. Link a card to its element and write on the card how to apply it. Your own images can become a furniture library too: an extracted piece can go in a catalogue, or you can use Remove Background and save it to Assets, as the Interior Design Assets tutorial shows. Arrangement Variations then gives you other layouts, as the panoramas and AI feedback workshop covers.

Asset records can hold estimated dimensions and possible supplier details, so treat them as a starting point when buying furniture, and measure each room before anyone orders. Formas has no separate staging tool; this is virtual staging done with its general studios, and it is useful for a show apartment that is not yet furnished. If you want a piece as a 3D model, right-click Convert to 3D saves it to the Asset Library, and Image to 3D exports a GLB. If the images reach a listing, check the rules in your market.

6. A floor plan buyers can read

The brochure needs a plan. Upload the 2D floor plan to Freeform, render it, then swap the tiles and flooring so it matches the approved rooms. The Formas floor plan guide adds a check worth making: correct moved doors or missing walls in the Iterative Editor before any room view. Setting a scale with two points and a known length lets you read area and perimeter from board geometry, which helps with a quick check, and the brochure's official areas should still come from your measured drawings. Generate Drawings can also make image versions of an elevation or axonometric, and these are generated images. If someone needs linework, Vectorize exports 2D PDF or DXF; check double lines and rescale afterwards.

If you have a model, the 3D model to image studio imports OBJ, 3DS, GLB, GLTF, STL, 3DM, FBX, PLY, IFC and SKP files, and Formas is directly integrated with SketchUp. Place assets, set cameras and use the sun chart for location, time and angle. That helps spatial planning conversations about daylight, as long as you present the results as visuals rather than a lighting study.

7. Run the other rooms through the same style

Now the second bedroom and kitchen go through the same style, and you can queue more perspectives while it runs. They will read as one apartment because the palette stays consistent, not because anyone matched them by eye. For a golden hour version of a room you have already approved, Enhanced Realism looks at the image in Design Chat, suggests changes such as Light Quality and Surface Realism, and lets you set each intensity, which gets you more realistic images without starting again.

8. Client delivery, in the format each person needs

Choose the output for the person receiving it:

• Brochure draft: Save Combined gives you a PNG. Upscale it for final artwork; 2K and 4K are on Pro and Pro Plus, and full-resolution, watermark-free exports start at Go.
• The agent's phone: Panorama 360 lets a buyer look around a room from one spot, with gyroscope on mobile, shared by link or QR code. It is a look-around view, so do not call it a walkthrough.
• Social posts: Instant Narratives turns stills into motion clips and camera moves, with a 4:5 ratio added in June 2026.
• A launch film: Video Shots builds concept video from stills, with storyboards, an AI director and templates such as brand campaign. The agents, Shots and Viewpoints workshop shows it.
• The developer's meeting: Presentation Agents, in Preview as of September 2026, turn selected images into editable PowerPoint slides.
• Comments in one place: Shareable boards on Pro and Pro Plus carry comments, and board collaboration was labelled Beta when last documented. Board Brief keeps project context on the board, and Peter can give a design opinion and compare two images before you send anything.

The agent now has several ways to help a buyer visualize ideas for the space.

Free options in Formas and elsewhere

Plenty of interior design AI software has a free tier or free version, usually with a limit on free designs or generations. When you compare free tiers, look at what output quality the free designs give you, not only how many you get. Formas gives you free templates in Drawing Studio and Style Transfer, along with free credits every month, which is a practical way to see its output quality on an existing space of your own.

Generations use credits, and the cost depends on the operation. Testing in Draft quality and sticking to one room helps those free credits go further. A paid plan adds what you need for delivery: Formas plans add full-resolution, watermark-free exports from Go upward, and 2K and 4K quality, shareable boards with comments and Style Memory across projects on Pro and Pro Plus. Starter comes with 750 credits a month. The photo apps in the table publish their own terms, so check their sites for current prices and limits.

How to choose interior design tools for your work

You want to refresh a room at home. Try Formas with a single photo and Smart Notes for one surface at a time, and describe the look you want, such as mid century modern. Remodel AI and other phone-based apps also offer quick style changes.

You want to buy what you see. Start in Formas to settle the look and see the furniture in your room before any purchase decision, then source products. REimagine Home links designs to purchasable furniture, and tools with catalogue matching are built for that step.

You are an interior designer working for clients. Use Formas for concept and presentation. Custom drawing styles, Assets, Smart Notes and panoramas cover those stages of a real design process, and AI improves client communication when people can see the options. Design professionals should still own the final call on layout, safety and budget.

You sell or let property. Formas tools can be applied to staging and presentation, and its founder names real-estate marketers and serviced-apartment operators among its users. Disclose altered images in your listings.

You are a student. Formas Campus offers education plans with Pro or Pro Plus features for enrolled students and active educators, checked against eligible schools.

Interior design AI software questions

Can AI software replace an interior designer?

No. Formas speeds up concepts and presentation, while layout, safety, budget and client judgment stay with the designer.

Can it produce FF&E schedules or construction drawings?

Formas asset records can hold estimated dimensions, materials and possible supplier information, and these are not verified specifications. Generated drawings explain a design, and they are not construction documents. Keep those deliverables in your own tools.

What will interior AI tools not do for me?

Formas images are generated, so they can invent details or alter things you did not point at. They are not surveys, and appearance alone does not establish measured dimensions or code compliance. Keep a measured drawing nearby for room layouts and anything you order. Output quality also depends on your source, so a clear photo in good light gives you more impressive results than a dim, wide-angle shot.

Try it on one real project

Pick a room from a live project, or the living room you want to change. Bring a photo, two material samples and one sentence on what must stay. In Formas Studio, use your free monthly credits to build a board from a free Drawing Studio template, then add a Smart Note for each material and generate two options. You will have something concrete to show your client, partner or buyer.
