Overview
CardStack connects your credit card wallet to Claude so you can get personalized answers about your Amex, Chase, Capital One, and other credit cards, benefits, rewards, and spending. Ask which credits are about to expire, which card to use for a purchase, whether you’re getting enough value from an annual fee, where you may be missing rewards, or what benefits you still have left to use. Instead of searching through Amex, Chase, and Capital One apps, benefit guides, and spreadsheets, CardStack gives Claude access to your actual CardStack wallet so it can help you make better decisions based on the cards you own. Use CardStack to: - Keep track of statement credits and benefits before they expire - Choose the best card for dining, travel, groceries, and other purchases - Understand your points, rewards, and card benefits - Review annual fees and the value you’ve received in return - Spot opportunities to earn more rewards from the cards already in your wallet If you use premium rewards cards from Amex, Chase, Capital One, or other issuers and struggle to keep track of everything they offer, CardStack turns Claude into a more useful credit card assistant.
