The Problem with Standard AI Design

Modus AI is different. Built by a Senior Engineering leader with a focus on spatial integrity, our app uses a proprietary Reasoning Pipeline to ensure every redesign is physically possible and personally relevant.

Why Modus AI?

  • Intelligent Spatial Constraints respect existing room geometry.
  • Functional Organization Mode maximizes storage and layout optimization.
  • Precision Furniture Mapping via an advanced image-to-image pipeline.

AI Interior Design App

Modus AI lets you redesign any interior space using your real room layout and real furniture. Generate multiple design styles, change décor, adjust lighting, and explore new layouts without replacing the items you want to keep. Every redesign is physically accurate and based on your actual room geometry.

AI Exterior Design App

Transform outdoor spaces including patios, decks, gardens, and full exterior facades. Modus AI applies architectural‑grade reasoning to ensure windows, doors, siding, and landscaping changes remain realistic and structurally possible.

Core Engineering Features

01. Keep Your Furniture With the Furniture Lock System

Identify and "lock" specific furniture pieces. Whether it’s a family heirloom or a brand-new sectional, our AI builds the new aesthetic around your existing assets.

02. Structural Redesign With Architectural Accuracy

Choose your level of transformation from Surface Level (paint/textures) to Structural Mode (wall removals/windows) with architectural accuracy.

03. AI Room Organizer & Space Optimizer

AI-driven suggestions to maximize storage and optimize furniture placement for small-space living, focusing on flow and utility.

04. Paint Color Visualizer (See Paint on Your Actual Walls)

High-fidelity texture mapping shows exactly how light interacts with specific colors on your actual walls, maintaining shadows and depth.

Frequently Asked Questions

Is there a free AI interior design app?

Modus AI is free to download and works on a credit system. Unlike competitors that charge $20-$40/month, Modus AI uses a pay-as-you-go model, so you never pay for a subscription you aren't using.

Can AI design my room but keep my furniture?

Yes. Modus AI features a specific "Refresh & Elevate" mode that identifies your existing sofas, tables, and cabinets and redesigns the room around them, updating only the decor, paint, and lighting.

How can I visualize paint colors in my room?

Use the "Paint Only" mode in Modus AI. It uses texture mapping to apply new colors to your walls while preserving shadows and lighting conditions for a realistic preview.

Does this work for exterior home design?

Absolutely. Modus AI includes specialized models for Exterior Facades, Garden Landscapes, and Patios. It respects architectural boundaries to ensure generated ideas are structurally possible.
