Satoshillo

A browser extension that converts ARS, USD, and EUR prices to satoshis in real time on any website.

About

Satoshillo is a lightweight browser extension that instantly converts fiat prices you encounter while browsing into Bitcoin satoshis. It detects prices on any webpage — whether they're written as $1.500, €2.4B, USD/JPY 158.48, or 50 mil millones de pesos — and shows you the equivalent in sats with a single click.

The goal is to make Bitcoin the default unit of account in your daily browsing, helping you think in sats rather than depreciating fiat currencies.
