Booth Companion – Booth.pm Currency Converter, Price Tracker & Shopping Tools

Booth Companion is a privacy-focused Chrome extension for Booth.pm that converts Japanese Yen (JPY/¥) prices into your preferred currency and adds practical shopping tools for international buyers, VRChat users, VTubers, avatar creators, and digital-asset collectors.

See converted product and cart prices, search your Booth library and wish list, track price changes, import cart or wish-list items into the price tracker, compare products side by side, calculate bundle savings, highlight avatar compatibility, and mark items you already purchased or received as gifts. Booth Companion can also export your library, show detected product dependencies, calculate total spending and favorites value, highlight free items, and customize Booth with themes.

Currency conversion uses exchange rates updated twice daily, with an optional manual rate override and flexible number formatting. Estimated converted-price history charts help you understand how exchange-rate movement affected prices over 7, 30, or 90 days.

Your Booth account data is not collected, sold, or used for advertising. All Booth Companion settings are stored locally in your browser.
