HealthPrism: A Comprehensive Health Assistant Integrating Predictive Machine Learning and Generative AI

HealthPrism is a full-stack health diagnosis platform developed by Shally Kaushik and released on GitHub on June 8, 2026. Its core integrates random forest prediction models with Google Gemini generative AI, offering features such as heart risk assessment, stress detection, and personalized health guidance, using a React frontend + Flask backend architecture.

HealthPrism is an innovative AI-driven health diagnosis and wellness intelligent platform that combines predictive machine learning with generative AI coaching to provide a 360-degree health perspective. Unlike traditional data recording tools, it can proactively analyze health indicators, predict potential risks, and give personalized intervention suggestions, reflecting the trend of technology integration in the field of personal health management.

• Frontend: React19 + Tailwind CSS + Framer Motion + Recharts to implement a modern interactive interface
• Backend: Flask framework, JWT authentication + Bcrypt encryption, RESTful API to decouple ML inference, AI dialogue, and data storage
• ML Pipeline: scikit-learn for model training, Joblib for serialization, train script supports model iteration
• Data Storage: MongoDB (local/cloud-hosted), with sound privacy protection mechanisms
• Security: JWT authentication ensures user data security; it is stated that it is only for personal educational use

1. Heart Risk Assessment: Based on an 8-feature random forest/decision tree pipeline, outputs risk scores
2. Stress Detection: Physiological data + VADER sentiment analysis of diary text to capture mental state in a multi-modal way
3. AI Health Coach: Driven by Google Gemini1.5 Flash, provides contextual suggestions based on risk scores
4. Dynamic Nutrition Plan: Generates personalized meal plans based on real-time health indicators
5. Health Visualization: Recharts interactive charts to track historical trends of indicators

• Local Deployment: Backend requires Python3.9+ virtual environment; after installing dependencies from requirements.txt, start the Flask service. Frontend starts the development server after installing dependencies via npm
• Environment Configuration: Manage sensitive information such as Gemini API key, MongoDB connection string, and JWT key through backend/.env

• Technical Integration: Demonstrates the organic combination of predictive ML and generative AI in health scenarios
• Reference Value: Provides a full-stack AI application architecture example, especially the ML and LLM collaboration mode
• Industry Significance: Builds a health management closed loop (data collection → risk prediction → personalized intervention)
• Compliance: Standards for privacy protection and medical disclaimers, providing reference for applications involving sensitive health data
