The Voucher Genius Extension is a free Chrome add-on developed by Voucher Genius. It falls under the category of Browsers and the subcategory of Add-ons & Tools. This extension aims to help users find the best vouchers, promotion codes, and discounts while browsing, allowing them to save money on their online purchases.

Upon installation, the Voucher Genius Extension adds an icon to the top right bar of the Chrome browser. When users are shopping online, the extension automatically searches for vouchers and if any are found for the specific website or product, the icon changes color from blue to orange. Additionally, a number indicating the amount of vouchers found is displayed on top of the icon.
