cuanto

cuanto describes itself as "Google Lens for prices" and does one job: it lets you stop doing mental currency math in foreign shops. You point your camera at a shelf label, the built-in price finder reads the numbers on-device, and the result appears converted into the currency you have chosen as your "local shelf." Because the recognition engines run in the browser on your own processor, nothing is uploaded, and the tool can be used as a plain typed-price converter if you already know the number.

The practical setup is travel-oriented. Before a trip you open cuanto, let it download the scanner files and the exchange rates it needs, and then it keeps working as an offline price converter after you refresh. The project is deliberately minimal and privacy-first: there is no login, no account, and the page even warns that cuanto needs JavaScript because "everything runs on your device, nothing is uploaded."

That makes cuanto a lightweight companion for tourists, business travellers, cross-border shoppers, and anyone who has ever stood in an aisle juggling a phone calculator. It is not a finance or investing platform, and it does not give investment advice — it is simply a fast, private camera calculator for prices.
