Coupert: AI coupon finder + cashback

Coupert installs in one click from your browser's store (Chrome, Firefox, Edge, Opera or Brave). On each checkout page at a partner merchant, the extension automatically shows available promo codes and offers to test them. In one click, the AI tests all the codes in seconds and applies the one generating the biggest discount. The whole process takes under 10 seconds, with no manual copy-paste and without leaving the checkout page.

Alongside promo codes, Coupert offers cashback on purchases made via its partner merchants. Unlike most cashback platforms that impose validation delays of several weeks, Coupert credits its refunds within a few days. Cashback accumulates in your Coupert wallet and can be withdrawn once the minimum threshold is reached. The extension activates cashback automatically, without you needing to manually activate a tracking link.

Coupert covers more than 200,000 merchants internationally, making it one of the broadest databases among promo-code extensions. This coverage includes major e-commerce sites (Amazon, eBay, ASOS, Nike, Adidas) as well as many specialised shops. The database is enriched daily: Coupert adds and validates up to 90,000 promo codes each day via its automated system, ensuring the tested codes are recent and active.

Coupert and Wanteeed are two widely used promo-code extensions. Coupert has a far larger network (200,000 merchants) and covers international purchases. Wanteeed is more focused on a curated set of partners with a native local-language interface. Coupert has cashback with short delays (days) versus 48h for Wanteeed. Both can be installed simultaneously but may create conflicts when testing codes — it's better to keep only one active during checkout.

Coupert promo codes apply when subscribing to or using the platform. However, since Coupert is itself a promo-code finder, the core of its service is free. One-off offers for new sign-ups (boosted cashback, welcome bonus, e.g. code 1FA981) are available on coupert.com or via referral links. The basic principle is that the extension is entirely free to use.

Coupert has a referral program that rewards users for each sign-up generated via their personal link. The bonus details (amount or extra cashback) are visible from the extension's account area or on coupert.com. The referral is activated as soon as the referee installs the extension and makes a first eligible purchase.

Coupert is developed by an international company with 8 million active users. The extension doesn't collect your banking data or passwords. It detects checkout pages via partner-merchant URLs to trigger the code search. Coupert is available on the official browser stores (Chrome Web Store, Firefox Add-ons) where each extension undergoes a security review. Compatibility with 5 browsers (Chrome, Firefox, Edge, Opera, Brave) attests to its technical robustness.

Coupert is primarily designed as a desktop browser extension. For mobile purchases, the Coupert app is available on iOS and Android and offers manual promo-code search for partner merchants. It doesn't automatically test codes like the desktop extension, but lets you view available offers and copy the best code before finalising an order in a merchant's app or mobile site.

Coupert is very well rated by users on browser extension stores, with positive feedback on the speed of code testing and the savings achieved. Users particularly appreciate no longer having to manually search for promo codes on dedicated sites. The rare negative reviews concern cases where no valid code is found for a given merchant, which is inevitable for shops that don't publish any.

Go to your browser's extension store (Chrome Web Store, Firefox Add-ons, Edge Add-ons, Opera or Brave) and search for "Coupert". Click "Add" or "Install" — the extension is active immediately. Create a Coupert account (optional but required for cashback) with your email. From your next online order, the Coupert icon lights up automatically on partner sites to offer codes and cashback.
