Money Navigation

Maps tells you which way to go. Money Navigation tells you which way to pay.

One AI assistant guides every payment abroad the cheapest way: at the ATM, the card terminal, the market stall and the exchange counter.

What the AI does for you

Six money jobs that travelers usually do by hand, done by one assistant.

1

Reads the ATM screen

Point the camera at the screen. It says which button to press; on the demo ATM, declining conversion keeps about 246 THB.

2

Reads Thai bills

It reads the receipt and checks the math: subtotal, discount, service charge and VAT. A bill is marked verified only when the numbers add up.

3

Hears the market seller

It hears the seller's price in Thai, judges it against a sourced usual range and speaks your counter-offer in Thai.

4

Tracks your cash

Cash on hand from ATM withdrawals, exchange and cash payments, with nearby ATMs and live exchange-counter rates.

5

Reads your card

It reads your card and fills in its foreign fees from the issuer's own page.

6

Morning briefing

From today's calendar, it shows what each stop needs and the payment traps nearby.

Why not an app you already have?

Others answer when you ask. Money Navigation answers before you pay.
