I-DAI (Intelligent Death AI)

🚀 Overview

I-DAI is a predictive web application that uses AI models to analyze user data (e.g., age, health status, lifestyle) and generate predictions on potential causes of death. The project integrates Next.js, MongoDB, NextAuth.js, Zustand, and React Query, ensuring a seamless user experience with secure authentication and efficient state management.

🛠️ Tech Stack

• Frontend: Next.js (React, TypeScript)
• State Management: Zustand
• Data Fetching & Caching: React Query
• Authentication: NextAuth.js (JWT-based)
• Database: MongoDB (Mongoose ODM)
• Backend: Next.js API Routes
• Deployment: Vercel / AWS

✨ Features

✔ User Authentication & Authorization – Secure login via NextAuth.js with JWT session handling.
✔ Dynamic AI-Based Predictions – Users enter personal and health data, and the AI model provides an analysis.
✔ State Management with Zustand – Optimized global state for UI responsiveness and better performance.
✔ Efficient Data Fetching with React Query – Ensures fast and cached data loading.
✔ Scalable Backend with Next.js API Routes – Handles AI model requests and user data securely.
✔ MongoDB Integration – Stores user data and AI predictions with Mongoose ORM.
