Show HN: AI that picks your best credit card for every purchase

https://payvo.ai
1•iman_malhi•1d ago
Last year I left $2,400 in rewards on the table by using the wrong credit cards.

I have 5 cards with different reward rates: 5% groceries on one, 3% gas on another, 2% dining elsewhere. Mentally tracking which card to use where is exhausting, so I defaulted to whatever was in my wallet.

I built Payvo to solve this. It automatically routes each transaction to your optimal card for maximum rewards.

How it works:

Add your credit cards once (we track 180+ cards, 29 loyalty programs)

AI analyzes transactions in real-time

Routes to your best card per category

30-40% more rewards, zero mental overhead

Currently in beta and looking for early users. Sign up at payvo.ai if you're interested in testing it out.

Targeting the 45M Americans with multiple credit cards who are leaving money on the table like I was.
