Decorous (officially "AI Interior Design by Decorous") is a mobile app built by a solo developer that uses generative AI to transform room photos into fully styled interior designs. Available on both the Apple App Store (ID: 1664988827) and Google Play, Decorous lets homeowners, renters, and design enthusiasts visualize room makeovers without hiring a professional interior designer.
The app works by analyzing a photo of any room — living room, bedroom, kitchen, bathroom, or entryway — and generating AI-powered design suggestions tailored to the specific space. Users choose from a variety of popular interior design styles including Mid-Century Modern, Industrial, Scandinavian, Bohemian, Minimalist, and more, then select from curated color palettes to match their desired aesthetic.
Decorous holds a 4.5 out of 5 rating on the App Store with over 106 ratings. Users praise its ease of use, with one reviewer noting: "I could spend hours drawing renovation inspiration from this app." The app has recently made all Pro features available for free.
A standout feature is the built-in AI Chat Designer, which lets users have a conversation with an AI assistant about their space to receive further customized suggestions. This interactive approach goes beyond static style transfers, allowing for iterative refinement of design ideas based on personal preferences, budget constraints, and room dimensions.

Does Decorous Have a Free Version?
Yes — Decorous is now entirely free. The app is free to download on both the Apple App Store and Google Play Store, and all previously premium Pro features have been unlocked at no cost. This includes unlimited AI room redesigns, access to all design styles, all color palettes, and the AI Chat Designer feature.
Previously, the free version of Decorous limited certain features behind a Decorous Pro paywall, with subscription options at $3.99, $9.99/month, $34.99/year, or a $29.99 lifetime purchase. That paywall has since been removed, making Decorous one of the few fully free AI interior design apps with no usage restrictions or watermarks.

How to Use Decorous: A Step-by-Step Beginner Guide
Getting started with Decorous takes just a few minutes. The app is designed for users with zero interior design experience — no technical skills or design knowledge required.
Step 1: Download the App
Install Decorous from the Apple App Store (iOS) or Google Play Store (Android). The app is free with no in-app purchases required.
Step 2: Snap a Photo of Your Room
Open the app and take a photo of the room you want to redesign, or upload an existing photo from your camera roll. Decorous works with any room type — living rooms, bedrooms, kitchens, bathrooms, dining rooms, entryways, and home offices all produce quality results.
Step 3: Choose a Design Style
Select from popular interior design styles including Mid-Century Modern, Industrial, Scandinavian, Bohemian, Minimalist, Japandi, Contemporary, Rustic, Art Deco, and more. Each style applies a distinct aesthetic to your room photo using generative AI.
Step 4: Select a Color Palette
Pick from a range of curated color palettes that match the mood you want to create — warm earth tones, cool neutrals, bold accent colors, or monochromatic schemes. The AI adapts the design output to reflect your chosen palette.
Step 5: Chat with the AI Designer
Use the AI Chat feature to discuss your space further. Ask questions like "What furniture would fit this corner?" or "How can I make this room feel larger?" The AI designer provides personalized suggestions based on your specific room dimensions and style preferences.
