Health AI

Your AI-powered wellness companion for mental health and physical fitness.

Comment

Inspiration

The inspiration for Health AI came from witnessing the growing mental health crisis and the increasing need for accessible healthcare solutions, especially during and after the COVID-19 pandemic. I noticed that:

  • Mental health isolation was affecting millions of people who couldn't access traditional therapy
  • Remote work posture issues were becoming widespread health problems
  • Lack of personalized health guidance left people with generic, ineffective advice
  • High costs and long wait times prevented many from getting the help they needed

I wanted to create a platform that could provide immediate, AI-powered health support that was both professional and compassionate, making wellness accessible to everyone regardless of their location or financial situation.

What it does

Health AI is a comprehensive wellness platform that provides:

🤖 AI Therapist Chat

  • 24/7 mental health support through conversational AI

  • Crisis detection and appropriate resource recommendations

📷 Posture Analysis

  • Real-time camera-based posture assessment
  • AI-powered analysis of body positioning and alignment
  • Progress tracking with detailed improvement recommendations
  • Multi-camera support with zoom and capture features

📊 Health Dashboard

  • Comprehensive health metrics and progress visualization
  • Personalized insights based on user activity
  • Data persistence across sessions with user authentication
  • Progress tracking across all health tools

🔐 Secure User Management

  • Supabase authentication with email/password and magic links
  • User-specific data isolation and privacy protection
  • HIPAA-compliant data handling practices
  • Row Level Security for sensitive health information

How we built it

Frontend Architecture:

  • Next.js 15 with App Router for modern React development
  • TypeScript for type-safe, maintainable code
  • Material-UI for professional, accessible components
  • Framer Motion for smooth, engaging animations
  • Tailwind CSS for utility-first styling

Backend & Database:

  • Supabase for backend-as-a-service with PostgreSQL
  • Real-time subscriptions for live data updates
  • Row Level Security (RLS) for database-level security
  • Authentication system with multiple login methods

AI & External Services:

  • OpenAI API for natural language processing and health analysis
  • Web Speech API for voice recognition and synthesis
  • Computer Vision for real-time posture analysis
  • Custom AI service layer for unified API management

Data Management:

  • Hybrid storage approach - localStorage for immediate access, Supabase for cloud backup
  • User-specific data isolation with metadata verification
  • Progressive data loading for optimal performance
  • Automatic data cleanup and validation
