The big news
Stop losing money every time you pay abroad. Money Navigation is one AI travel assistant that reads the ATM or card-terminal screen through your phone camera and tells you which button to press. It also checks restaurant bills for padded charges, helps you haggle in Thai by comparing prices with usual ranges, and tracks how much cash you have left. Small choices like declining an ATM's conversion add up fast. This app turns every split-second payment decision into a smart one, in any language.

It uses on-device text recognition for ATM and terminal screens, Cloud Vision and Gemini for bill checking, and Google speech services for Thai haggling. Backend runs on Supabase with PostgreSQL and Deno edge functions, plus the ThaiRate API and Google Maps.
