�🎨 Key Features Explained

Spaced Repetition Algorithm

Recallify implements a modified SM-2 algorithm that:

Schedules reviews based on recall strength (0-100)
Adjusts intervals based on answer confidence
Optimizes for long-term retention (currently at 94.8% vs 72% average)

Gamification System

XP Formula: Base XP × Difficulty Multiplier × Streak Bonus
Level Progression: Exponential curve requiring ~1.5x more XP per level
Streak System: Daily study maintains streaks with 24-hour grace period

AI Insights

Mock AI system provides:

Optimal study time recommendations
Deck mastery predictions
Cognitive load warnings
Personalized study strategies

🗓️ Roadmap

Phase 1: Backend Integration ⏳

REST API development
User authentication & authorization
Database schema design (PostgreSQL/MongoDB)
Card CRUD operations
Session tracking & analytics storage

Phase 2: Core Features 🎯

🌈 3D interactive landing page
📱 Fully responsive design

🏗️ In Progress

⚙️ Backend API development
🗄️ Database integration
🔐 Real authentication system

📋 Planned

🤝 Contributing

Contributions are welcome! This project is currently in frontend-only stage. The backend integration is the next major milestone.

How to Contribute

Fork the repository
Create your feature branch (git checkout -b feature/amazing-feature)
Commit your changes (git commit -m 'Add some amazing feature')
Push to the branch (git push origin feature/amazing-feature)
Open a Pull Request

Development Guidelines

Follow the existing code style
Use TypeScript for type safety
Write meaningful commit messages
Test your changes across devices
Update documentation as needed

📝 Environment Variables

Currently, no environment variables are required as the app uses mock data. Once backend is integrated:

VITE_API_URL=http://localhost:3000/api
VITE_WS_URL=ws://localhost:3000

🐛 Known Issues

Mock authentication doesn't persist across refreshes
All data resets on page reload (no backend yet)
Some animations may be heavy on low-end devices
Three.js hero scene needs optimization for mobile
