Never use the wrong card at checkout again.

Perqt's browser extension reads the site you're on — DoorDash, Marriott, Amazon Fresh, Shell — and tells you which card in the market earns the most. One click and you're done.

Under the hood

How it actually works

A small popup in your toolbar with a single job — tell you which credit card earns the most on the site in front of you.

  1. Step 01
    You open a site
    Browse to any merchant — doordash.com, marriott.com, amazon.com, shell.com. The extension stays dormant until you click it.
  2. Step 02
    You click the icon
    The popup reads only the hostname of the current tab. It does not read page contents, URLs, form fields, or your cart.
  3. Step 03
    We map the category
    Perqt matches that hostname to a spend bucket (Dining, Hotels, Groceries, Gas, etc.) using our merchant database.
  4. Step 04
    You see the best card
    The popup shows the highest-earning card on the market for that bucket, the multiplier (e.g. 10×), and the points program it earns.
Works on
Any desktop Chromium browser
  • • Chrome, Edge, Brave, Arc, Opera on Mac, Windows, Linux, and ChromeOS.
  • • The web app in any of those desktop browsers — including when you're signed into Perqt.
  • • 100+ merchant sites across dining, hotels, airlines, gas, groceries, streaming, drugstores, warehouse clubs, and home improvement.
Doesn't work on
Phones & tablets
  • • iPhone & iPad — Safari, Chrome, and Edge on iOS don't support browser extensions at all (Apple only allows Safari Web Extensions, a different format).
  • • Android — Chrome on Android doesn't support extensions.
  • • Safari on Mac — different extension format; not supported yet.

On mobile, use the Perqt app or Best card for… directory instead.

Boundaries

What Perqt doesn't do

We're not Honey. We're not Rakuten. We're not autofill. Here's exactly where the line is.

Doesn't auto-pay
It can't fill your card number, autofill checkout forms, or complete a purchase. You still pick the card and pay normally.
Doesn't read your cart
We only see the hostname (e.g. "amazon.com") of the active tab when you click. No browsing history, no page content, no form fields, no cookies, no PII.
Doesn't apply coupons
Perqt isn't Honey or Rakuten. It tells you which card to use — it doesn't add discount codes or route through affiliate links.
Doesn't know your wallet (signed-out)
By default it shows the best card on the market. Sign in to Perqt to see the best card you already own instead of one you'd have to apply for.
Doesn't track you
No background script, no analytics pixels, no telemetry. The popup only runs when you open it.
Doesn't work on every site
If a site isn't in our merchant database (e.g. a small local shop), the popup tells you to fall back to your everyday flat-rate card.
