Koorooreads what you’re buying and quietly tells you which card in your wallet earns the most. AI-powered, so it works on any store — not just the obvious ones.
No account to create. No card numbers handed over. Your wallet list lives on your device and nowhere else.
Tell Kooroo which cards you own — just the names, never the numbers. Stored locally, encrypted, never synced.
When you reach a checkout, Koorooreads the merchant category and ranks your cards by what they’ll actually earn.
A small overlay names the best card, the points you’ll earn, and the math behind it. That’s the whole product.
If you already keep three or more rewards cards in rotation, you’re probably leaving points on the table at checkout. We close that gap without changing the way you shop.
AI figures out the merchant category for any store — including weird edge cases hardcoded rules miss (subscriptions, marketplaces, Target Online, and so on).
We literally can’t see them. Kooroo only stores card names — Chase Sapphire, Amex Gold — on your device.
Eighty-plus cards across both markets. Region-aware: Americans see U.S. cards, Canadians see Canadian. Travellers can override.
Sub-second recommendations. Dismissible per-site. Never covers the “Pay” button. Easy to ignore when you don’t need it.
When a card you don’t own would beat your best by a wide margin, we say so — annual fee shown up front. No tricks.
Core recommendations stay free. We earn a commission only when you choose to apply for a new card through us — and it doesn’t bias what we recommend from your wallet.
We’re finalizing the Chrome Web Store submission. In the meantime, early testers can install the extension directly — takes about two minutes.
