Never wonder which card to use again.
CardWise looks at where you're about to spend and tells you which card in your wallet earns the most — cash back, points, or miles — before you pay.
How it works
1. Type the merchant or place you're buying from (or tap a quick category like Restaurant, Gas, or Grocery).
2. CardWise matches it to a reward category using a reviewed catalog of merchants and official card terms.
3. See your best card, why it wins, and how it compares to your other cards — in seconds.
Built around your real wallet
Add the cards you actually carry from a catalog of reviewed official templates, or request one that's missing. Track rotating categories like Discover's quarterly 5% bonus, including quarters with multiple active categories at once.
Turn on the assistant and just ask: "which card for dinner?", "am I missing any rewards?", or "add the Venture X". It checks your own wallet against reviewed card terms, and it never changes your wallet without asking you first. The assistant uses AI, so answers can be wrong — check terms with your issuer.
Privacy by design
CardWise doesn't ask you to log in, doesn't track you, and never asks for or stores purchase amounts. Your wallet lives on your device. The assistant is off by default; if you turn it on, your questions and the cards in your wallet are sent to CardWise's assistant service and its AI provider to answer you, and conversations are deleted within 24 hours. Leave it off and nothing about your wallet ever leaves your phone.
