An interior designer's daily routine is a race against time. Client meeting in the morning, site visit at midday, and in the evening trying to finish that moodboard due tomorrow. On top of that, you still need to render 3 living room options, a kitchen, and the master suite. And the client wants to see "how it will look" before approving anything.
AI entered interior design to solve exactly that. Not to replace the designer's eye. To accelerate everything that gets stuck between the idea and the presentation.
What interior designers actually need from AI
Unlike architects focused on facades, structure, and site planning, interior designers live in the details. The exact leather tone of the sofa. The reflection of polished porcelain tile. The way a pendant light casts shadows on a plaster wall. If the render doesn't capture those details, it's useless.
That's why generic AI tools don't work for interiors. ChatGPT generates a pretty "modern living room," but the materials are invented, the lighting is generic, and the proportions don't match the project. You can't show that to a client and say "this is how it will look" when the AI swapped the porcelain for marble and added a window that doesn't exist.
Interior designers need AI that understands materiality, ambient lighting, and furniture scale. AI that takes the real project and renders it with the right textures, the right light, in the right proportions.
Interior rendering: from hours to seconds
Interior rendering is the hardest thing to get right with traditional software. Global illumination, reflections in glass and metal, light bounce in fabrics, transparency of curtains. In V-Ray, that means hours of configuration and rendering. In Lumion, results are fast but generic — that look of "almost real but not convincing."
With AI trained specifically for architecture and interior design, the situation changes. You upload a screenshot of your project modeled in SketchUp, Revit, or ArchiCAD and in 20 to 40 seconds you receive a render with convincing natural lighting, textures faithful to the project materials, and reflections that make sense in context.
Redraw was trained on millions of real interior images. The AI knows how polished porcelain tile reflects. It knows the difference between linen and velvet on a sofa. It knows how a recessed spot light creates a gradient different from natural window light. Those are the details that determine whether a render convinces or not.
And when the client looks and says "I want to see it with wood flooring instead of porcelain," that's 30 seconds to generate the variation. Not 2 hours reconfiguring materials.
Enhance Render: when you already have an image
Many designers already render with Lumion, Enscape, or even photos of the space under construction. The problem is that the result doesn't always reach the presentation level clients expect.
Redraw's Enhance Render was built for this. You upload any image (software render, photo of the space, even a Promob screenshot) and in 30 seconds the AI improves textures, corrects lighting, adds realism. That render that was "almost good" becomes professional. That raw construction photo becomes a presentation.
For interior designers, this feature alone justifies the tool. Because much of the work is taking what exists and elevating it. AI does that in seconds.

Idea generation: when the client doesn't know what they want
Every designer knows this situation: the client sits down, says "I want something modern but cozy," and expects you to translate that into an image on the spot.
With AI, you can. In Redraw, idea generation works like visual brainstorming. Describe the concept ("living room with neutral palette, double ceiling height, warm lighting, japandi style"), and the AI generates options in seconds. These aren't final renders — they're starting points. Visual references you show the client, adjust the direction, then render with precision once the project is modeled.
It's automated moodboarding. Instead of spending 3 hours on Pinterest searching for images that "sort of" represent the idea, you generate exactly what you're envisioning. And if the client says "I like it but want more color," generate again in 30 seconds.
Visual moodboard with AI
Speaking of moodboards: the way designers present concepts to clients has changed. The classic moodboard (a collage of Pinterest photos with material samples) works, but has one problem. The photos are of other people's projects. They don't show how your client's project will look.
With AI, the moodboard becomes personalized. You generate images of the client's actual space with different styles, palettes, and atmospheres. The client sees their space rendered 5 different ways. Not a generic Pinterest living room. Their living room.
That changes the conversation. The client stops comparing with other people's photos and starts deciding about their own project. Approval comes faster because expectations are calibrated from the start.
Textures and lighting: where AI makes the difference
Interior design is about sensation. The feeling of a space comes from the combination of materials, light, and proportion. And that's exactly where generic AI fails and AI trained for interiors succeeds.
Redraw has its own models fed with millions of real interior images. Not renders, not generic AI images. Real photos and renders from executed projects. The AI learned how real materials behave:
How freijo wood reflects light differently from oak. How curtain fabric filters natural light creating a warm tone. How a mirror expands the space but changes the perception of depth. How Calacatta marble has veins that run in a specific direction.
Generic AI doesn't know this. It generates a generic "wood floor." Redraw generates materiality that a designer recognizes.
The complete designer workflow with AI
In practice, an interior designer can do everything inside Redraw:
1. Generate ideas with the client. In the first meeting, you describe the concept and generate visual options in real time. The client participates, gives feedback, and guides the direction. You leave the meeting with the concept approved.
2. Render the modeled project. When the 3D model is ready, take a screenshot and render in 30 seconds. With the materiality and lighting the project calls for.
3. Generate finish variations. Does the client want to see it with dark flooring? With granite countertop instead of quartz? With cooler lighting? 30 seconds per variation.
4. Enhance existing renders. Rendered in Lumion or Enscape and the result looks generic? Upload to Enhance Render and in 30 seconds gain realism.
5. Generate a video of the space. Want to show the space with movement? Redraw has its own video tool for interiors, plus Veo 3 and Kling AI. Turns a static render into a walkthrough.
6. Generate 3D objects. Need a specific light fixture, a vase, a piece of furniture not in your library? Generate it directly in Redraw and import into SketchUp.
One platform. The entire visual workflow of an interior designer solved.
Cost vs. savings
A designer who renders with traditional software spends on average:
Render license (Lumion/Enscape): R$ 3,500 to R$ 7,000/year
Adequate hardware: R$ 8,000 to R$ 20,000 (amortized ~R$ 5,000/year)
Hours in rendering and configuration: ~60 hours/month
Hours in moodboards and references: ~15 hours/month
Total: R$ 8,500+/year + 75 hours/month
With Redraw:
Basic plan: ~R$ 1,000/year
Hardware: the laptop you already have
Hours in rendering + ideas + variations: ~2 hours/month
Total: R$ 1,000/year + 2 hours/month
That's 73 hours a month returned to you. Almost 10 working days. Imagine what you do with 10 extra days a month: more projects, more clients, or simply less stress.
Frequently asked questions
What is the best AI for interior design?
Redraw is the benchmark for interiors in 2026. With models trained specifically for interior spaces, it understands materiality, ambient lighting, and furniture scale like no generic AI can.
Can AI render interiors with fidelity?
Yes, when trained for it. Redraw preserves textures, proportions, and lighting from the original project. Generic AI like ChatGPT invents materials and changes the geometry.
Can I use AI to create a moodboard?
Yes. In Redraw, idea generation creates personalized moodboards of the client's actual space, not collages of third-party photos. The client sees their own space in different styles.
Does AI for interiors work without a 3D model?
Yes. Idea generation works from a text description or reference image. Maximum-fidelity rendering uses a 3D model screenshot, but it's not required to get started.
Does Redraw capture the material details that matter in interiors?
Yes. The models were trained on millions of real interior images. The AI differentiates types of wood, fabric, stone, metal. It understands how each material reflects light differently.
