-A modern, lightweight AI Image Generator powered by Google ImageFX (Whisk), Grok, and Meta AI. Built with Next.js 14, TypeScript, and Tailwind CSS.
+A modern, full-stack AI Image Generator with **FastAPI backend** and **Next.js frontend**. 
+Powered by Google ImageFX (Whisk), Grok, and Meta AI.
+
+## 🆕 What's New in V3
+
+- **FastAPI Backend** - Python backend with automatic Swagger documentation
+- **Better Security** - Centralized CORS, Pydantic validation, structured error handling
+- **API Documentation** - Interactive docs at `/api/docs` (Swagger) and `/api/redoc`
+- **Improved Architecture** - Clean separation of frontend and backend
 
 ## 🚀 Quick Start
 
 ### Prerequisites
 - Node.js 18+
+- Python 3.11+
 - Whisk/Grok/Meta Cookies (from respective services)
 
 ### Installation
