Geography Nerd

I work with people all over the world and like knowing where places actually sit in relation to each other. Is Boston north or south of Toronto? (South, but barely.) Is New York north or south of Marseille? (South, by a lot more than you'd expect.) That curiosity turned into a weekend project once I realized GeoNames had every city I'd want to ask about.

The app is React 19 + Vite + Tailwind. After each guess, an OpenStreetMap view (rendered through React Leaflet over CARTO tiles) drops a pin on each city so you get the visual confirmation of where they actually sit. Built with AI tooling. No accounts, no install, no analytics, just two cities and four arrows.
