AirDNA — Your Air. Your Body. Your Future. Inspiration

Every day, millions of people check the Air Quality Index (AQI), but very few understand what those numbers actually mean for their own health.

An AQI of 180 might be a minor inconvenience for one person but could pose a serious risk to someone with asthma, allergies, or other respiratory conditions. Existing air quality applications focus on environmental data, but they rarely answer the most important question:

"What does today's air mean for me?"

That question inspired us to build AirDNA.

Instead of showing users another pollution dashboard, we wanted to create an intelligent companion that transforms complex environmental data into personalized health insights through a Digital Air Twin.

💡 What AirDNA Does

AirDNA combines:

🌍 Real-time Air Quality (AQI) 🌦️ Live Weather Data 📍 User Location ❤️ Personal Health Profile 🚶 Lifestyle & Travel Patterns 🤖 AI-powered reasoning

to generate a personalized Digital Air Twin.

Rather than displaying raw pollution values, AirDNA explains how current environmental conditions may affect a specific individual and recommends practical actions, such as:

Choosing a healthier travel route Finding the best time for outdoor activities Tracking pollution exposure over time Receiving personalized health recommendations Understanding environmental risks in simple language 🛠️ How We Built It

Our application is designed using a modern full-stack architecture.

Frontend Next.js React Tailwind CSS Backend FastAPI REST APIs AI Gemini for personalized recommendations and natural language explanations. Search & Analytics Elasticsearch for fast search, environmental indexing, geospatial queries, historical exposure analysis, and AI knowledge retrieval. Maps & Location Google Maps Platform Places Autocomplete Geocoding Directions API External Data Air Quality APIs Weather APIs ✨ Key Features 🧬 Digital Air Twin

Creates a personalized environmental health profile using the user's lifestyle, health profile, and live environmental conditions.

🛣️ Safe Route

Recommends routes that minimize pollution exposure instead of only optimizing travel time.

🌫️ Personalized AQI Insights

Explains what current air quality means for the individual rather than simply displaying an AQI number.

📈 Exposure Timeline

Tracks historical pollution exposure to help users understand long-term environmental trends.

🔮 Future Simulator

Allows users to explore how changing air quality conditions could influence their Digital Air Twin and health recommendations.

🤖 AI Health Assistant

Provides personalized, easy-to-understand recommendations powered by AI and grounded in real environmental data.

🚧 Challenges We Faced

One of the biggest challenges was integrating multiple real-time data sources while maintaining a smooth user experience.

We also had to:

Combine environmental data with personalized health information. Design a Digital Twin that updates dynamically without overwhelming users. Integrate mapping, routing, and geospatial services. Build a responsive interface that feels intuitive while presenting complex environmental information.

Another major challenge was transforming technical environmental data into recommendations that are meaningful and actionable for everyday users.

📚 What We Learned

Through this project we gained practical experience with:

AI-powered personalization Retrieval-Augmented Generation (RAG) Elasticsearch search and analytics Google Maps Platform Geospatial application design Full-stack system architecture Real-time API integration User-centered healthcare UX

More importantly, we learned that environmental data becomes far more valuable when it is personalized.

🚀 Future Plans

We plan to expand AirDNA with:

Wearable device integration Smartwatch notifications Predictive pollution forecasting Indoor air quality monitoring Community pollution reporting Health trend analytics Emergency environmental alerts Smart city integrations 🌱 Why AirDNA Matters

Air quality affects everyone differently.

Our vision is to move beyond reporting pollution levels and instead empower people with personalized, actionable health intelligence.

AirDNA transforms environmental data into meaningful daily decisions—helping people breathe smarter, travel safer, and live healthier.
