FamilyCircle

Inspiration

We wanted families to know not just where someone is, but how safe their location is in real time so that we can prevent worst case scenario events.

What it does

Real-time location tracking for multiple users, automatic risk scoring using AI analysis and SF crime data, and AI-generated explanations of danger levels.

How we built it

Integrated SF Open Data API (50K incidents) Added Firebase Realtime Database for live sync Implemented Haversine distance filtering Connected Claude AI API for explanations Built Leaflet.js map with color-coded risk zones

Challenges we ran into

Connecting so many different functions to work together as one cohesive project.

Accomplishments that we're proud of

Everything

What we learned

In-memory filtering beats databases for real-time performance The power of Claude lol How to use Firebase How difficult it is to make heat maps via real time data
