Ask the AI advisor anything about your wallet, get a daily digest of what needs attention, and stop paying annual fees for benefits you never use.
Hey Product Hunt! I built Cardzen because I kept paying big annual fees and then forgetting the credits that were supposed to justify them. Airline credits, dining credits, free nights, they quietly expire and the banks count on that. Cardzen puts your whole wallet in one place: it tracks every credit and perk, reminds you before they expire, and tells you which card to pull out for any purchase. There is also an AI advisor that knows your actual cards, so you can ask things like "which card should I book this flight with" and get a real answer. Free to try, and I would love your feedback on what to build next.
love how it actually breaks down which card to use per purchase instead of just showing a generic rewards list. the expiration reminders feel like the kind of thing you don't realize you needed until you see it.
The expiring credits problem is so real. Most people I talk to cannot name half the credits on their own premium cards, let alone the expiry dates. The daily digest angle is smart since the failure mode is not ignorance, it is forgetting. Congrats on the launch, Evan.
good to hear it's not pulling bank data, but that raises a different worry for me: if credit usage has to be manually marked as used, doesn't this relocate the problem instead of solving it? someone who forgets a $300 travel credit exists is, by definition, not the type of person who reliably remembers to open a separate app and log that they used it. what stops this from becoming another unused app on the home screen the same way the credit itself was an unused line item on the card?
congrats on the launch. building in personal finance too and the part that always looked like the actual hard problem here isn't the ui, it's the data. how are you pulling in credit/perk balances, is that plaid or something more card issuer specific? and what happens when an issuer quietly changes the terms mid cycle, does the user have to re-confirm or does it just drift out of sync
