SafeChild

Inspiration

Child safety and rapid emergency response remain critical concerns in Bangladesh. Traditional safety apps are often slow to navigate during high-stress situations. We built SafeChild to provide an immediate, hands-free child security platform that combines voice recognition, live GPS tracking, and real-time AI medical guidance.

What it does

SafeChild serves as an all-in-one emergency and safety companion:

Voice-Activated SOS System: Listens continuously for the trigger phrase "Help Help" via Web Speech APIs and automatically routes calls to emergency contacts.
Live Geolocation Mapping: Integrates Leaflet.js and OpenStreetMap to render real-time user displacement with custom electric cyan pulsing markers.
First Aid Conversational AI: Powered by Gemini 2.5 Flash to deliver empathetic, step-by-step first-aid guidance in both Bangla and English.
National Safety Redirection: Includes direct fallback controls to route emergency actions to the 999 National Emergency Desk.

How we built it

Frontend: Built using React, TypeScript (App.tsx, main.tsx), and Tailwind CSS with a dark Midnight Blue and Neon Red aesthetic.
AI & Geospatial: Integrated @google/genai (Gemini 2.5 Flash) for bilingual medical guidance, paired with HTML5 Geolocation and Leaflet.js.
Devin Integration: Devin AI was utilized to audit Web Speech API event listeners, optimize edge execution handlers, and refactor alternating emergency contact routing state.

Challenges we ran into

Managing continuous background audio tokens for the "Help Help" voice trigger without causing high CPU usage or browser throttling.
Ensuring zero-latency fallback between local contact numbers and national emergency services during connection drops.
Crafting medical prompt boundaries for Gemini 2.5 Flash to ensure clear, empathetic, and safe first-aid walkthroughs without hallucinations.

Accomplishments that we're proud of

Successfully implemented hands-free audio emergency triggers alongside live dynamic map tracking.
Designed an accessible, high-contrast Neon-Soft Minimalist UI optimized for fast stress-free navigation.
Delivered a fully localized emergency safety solution specifically built for Bangladesh's infrastructure.

What's next for SafeChild

Geofencing Alerts: Allow parents to mark safe zones and receive automated notifications if a child leaves the perimeter.
Offline First-Aid Mode: Cache core medical walkthrough steps locally so first-aid advice is accessible without cellular data.
