How it works

Quiz once. Right card at every checkout.

No spreadsheets, no login, no jargon. Tell us what's in your wallet and how you spend — the extension does the thinking from there.

STEP 01

Pick your cards

Tap the cards you already carry. We cover Chase, Amex, Capital One, Citi and dozens more.

STEP 02

Tell us how you spend

A bit, some, or a lot — across dining, travel, groceries and more. Gut feel is plenty.

STEP 03

Get the call at checkout

Every card scored in your Rundown — then the extension pops up wherever you shop and names the card to swipe.

Your report

Your whole wallet, swipe by swipe.

The quiz builds a plain-English report on every card you carry. Keep, swap, or add — and the extension carries that answer to every checkout.

Why trust us

We don't get paid to recommend cards.

Most "best card" sites earn a commission when you sign up. We don't. Our only job is to be right.

No affiliate fees

Zero sponsored placements, zero referral kickbacks. The ranking you see is the honest one — based purely on how you spend.

Data stays on your device

Your cards and spending never leave your browser. There's no account to create and nothing for us to sell.

Show-your-work math

Every number traces back to your spend × each card's real reward rate. Tap any figure to see exactly how we got there.

Built by points nerds who got tired of biased "best card" lists. No catch — just the math.
