🚀 Inspiration

Every day, countless voices go unheard—those displaced, forgotten, or invisible to systems meant to protect them. We realized that if technology can recognize faces, write poetry, and drive cars—why can’t it also listen to the homeless and help? NOMAD was born from this belief: Not One More Abandoned & Displaced.

💡 What it does

NOMAD is an AI-powered humanitarian assistant that allows frontline workers to record or upload voice samples from homeless individuals. It then:

Transcribes audio using Whisper

Extracts structured information (name, location, family, conditions) using NLP

Predicts urgency levels using XGBoost

Visualizes global data through a dynamic heatmap And all of this is wrapped in a secure, responsive, privacy-conscious web platform.

🛠 How we built it

Frontend: HTML, CSS, JS with Leaflet.js for heatmap rendering

Backend: Flask + Python with MongoDB Atlas for persistence

Audio: OpenAI’s Whisper for transcription

NLP: Gemini API for structured data extraction

ML: XGBoost model predicting urgency from encoded features

Bonus: JWT Auth, audio recording in-browser, mock alerts for social worker/NGO outreach

🧱 Challenges we ran into

Converting raw voice into actionable, structured data wasn’t easy

Handling inconsistent user inputs across different formats

Training a usable model with meaningful urgency scores

Ensuring privacy and ethics while dealing with sensitive data

Juggling ML, NLP, UI/UX, and full-stack architecture within 36 hours!

🏆 Accomplishments that we're proud of

Built a fully functional end-to-end platform in under 2 days

Seamlessly integrated AI, ML, and geospatial data into a single flow

Delivered real-time urgency predictions with meaningful impact

Created something that could genuinely help those forgotten by society

And perhaps most importantly—gave voices back to the voiceless.

📚 What we learned

Working with real-world humanitarian problems requires deep empathy

ML is powerful—but useless without ethical and contextual design

Transcription and NLP pipelines are messy, but extremely rewarding

How to hustle, fail, and innovate—together—as a team with purpose

🔮 What's next for NOMAD

Real-time outreach integrations (NGO dashboards, city alerts)

Multi-language support for transcription + extraction

Mental health triage and recommendation systems

Analytics dashboard for civic and social organizations

Offline capabilities for field workers

Partnering with shelters, hospitals, and relief efforts to deploy NOMAD where it’s needed most
