Build an AI-Powered Room Interior Design App with Next.js and AI

Welcome to the ultimate guide on creating an AI-driven room and home interior design application. This comprehensive walkthrough covers building a full-stack solution using React, Next.js, and AI. An accompanying video demonstrates the entire process step-by-step.

This application transforms any room into beautifully designed interiors using AI. Users upload room images, select design styles, and receive AI-generated concepts. The platform includes user authentication, credit management, and PayPal integration for a seamless experience.

Getting Started: Landing and Login Screens

The journey begins with an engaging landing screen showcasing how AI elevates interior design. From here, users navigate to the authentication section. This dual approach supports both social logins (like Google and Facebook) and traditional email/password authentication.

New users create accounts through a streamlined sign-up process. Existing users simply enter their credentials to access their personalized dashboard. This secure foundation ensures user data remains protected while enabling personalized experiences.

The Dashboard: Your Interior Design Hub

After logging in, users land on their dashboard – the central hub for all interior design projects. First-time visitors see an empty state, clearly indicating where to begin. The top bar displays critical information including available credits, profile settings, and quick navigation options.

Key dashboard features include:

• Credit balance tracker showing remaining design generations
• Profile management section for account details
• “Buy More Credits” option for premium features
• Navigation back to the main dashboard

As users generate designs, completed projects populate the dashboard. Each design saves to the server, allowing unlimited access to previous creations. This persistent storage ensures users can revisit and share their favorite concepts anytime.

Uploading and Designing Your Room

Creating a new design starts with clicking “Redesign New Room” from the dashboard. This redirects users to an upload interface where they select a room photo. Users then specify room type (bedroom, kitchen, office) and choose from various interior design styles like modern, minimalist, or rustic.

Advanced customization options allow users to add specific requirements before generation. Clicking “Generate” triggers a custom loading indicator while AI processes the image. The system handles all design transformations automatically.

Once complete, users see a split-screen comparison: original image alongside the AI-enhanced design. A download button provides access to the full-resolution image. Each generation consumes one credit, automatically deducted from the user’s balance.

Credits and Payment Integration

Credits drive the application’s freemium model. Users receive initial credits to start designing, with options to purchase more when needed. The “Buy More Credits” section offers flexible packages – for example, 25 credits for $4.

Payment processing integrates seamlessly with PayPal. Users can pay directly via PayPal or link debit/credit cards. This secure gateway enables developers to monetize the app while providing multiple payment options for convenience.

The SaaS structure ensures recurring revenue potential. Users can purchase credits in bulk, encouraging continued engagement. Transparent credit tracking maintains trust and helps users manage their design budget effectively.

The Technology Stack

This full-stack application leverages modern technologies for optimal performance:

• Next.js: React framework for server-side rendering and fast performance
• Neon PostgreSQL: Serverless database for scalable data storage
• Drizzle ORM: Type-safe database operations for efficient CRUD management
• Clerk: Authentication with multiple social login providers
• Firebase Storage: Secure asset hosting for user-uploaded images and generated designs

Even beginners can follow this guide. The tutorial covers everything from initial setup to deployment, ensuring comprehensive learning regardless of prior experience with React or Next.js.
