Perqt — Best card at checkout

Perqt tells you which credit card to use before you pay. Open the Perqt icon on any merchant site and the popup shows the highest-earning card for that merchant's spend category — dining, hotels, airlines, gas, groceries, streaming, drugstores, warehouse clubs, home improvement, and more — along with the multiplier and the rewards program it earns. When the top rate requires an issuer booking portal, the popup names the portal and also shows the rate you earn booking direct — so a portal-only rate is never presented as if it applies everywhere. What it does - Identifies the merchant category from the site you're viewing - Shows the best-earning card on the market for that category - Shows the multiplier (for example 4x) and the points or miles program - Links through to the full card detail page on Perqt What it does not do - No autofill. It never touches your card number or your checkout form. - No coupons or affiliate redirects. It is not a coupon extension. - No background script, no telemetry, no tracking pixels. The popup only runs when you open it. Perqt is a premium wallet for annual-fee cardholders. The extension is the checkout surface of that wallet; the full product at perqt.ai tracks your card benefits, credits, and annual-fee ROI.
