The RightCard Chrome extension

A free Chrome extension · in the Chrome Web Store · Chrome on a computer (Mac, Windows, Linux, ChromeOS) · works with or without the iPhone app

Your bank gives you card-linked offers and then makes you click "Add to card" on every single one. This adds them for you, on your bank's own page, while you are signed in as yourself. Then it tells you which of your cards has an offer at the store you are shopping.

How it works

1. Sign in once with your email. A six-digit code, no password to invent. If you use the iPhone app, use that same email and both surfaces share one set of offers.
2. Open your bank's offers page the way you always do: Amex Offers, Chase Offers, Citi Merchant Offers, Wells Fargo Deals.
3. It reads the offers on that page and saves them to your account. Turn on Auto-add and it clicks "Add to card" for each one too. Offers your bank stops showing come off your list, so what you see is what the bank still has.
4. Shopping somewhere? Click the RightCard icon on the store's site and it names the card that already has an offer there.

What it never does

Which banks

Phone and computer, one account

Offers you add in Chrome show up on your phone, and the ones your phone picked up in Safari show up in Chrome. The iPhone app is where the answers live: it picks the best card at any store from your whole wallet, folds in this quarter's rotating bonuses, and warns you when a store's merchant code means the bonus will not post. The extension is optional and so is the app; each works alone.

Questions

Chrome says "not trusted by Enhanced Safe Browsing". Should I worry?

No, and I would rather explain it than have you guess. That notice is about the listing's age, not its code. Google grants "trusted" status to developers who have been in the Chrome Web Store for a while with no policy violations, and it generally takes a few months for a new developer. This listing went live on September 16, 2026. Nothing about it can be fixed from my side, and it clears on its own.

What you can check instead of taking my word for it: the extension has no bundler and no remote code, so the package Google reviewed is byte-for-byte the source in the repository. Its permissions are listed in full here, including the two it deliberately does not request. Every Chrome user sees the same permission list at install time. If you would rather wait a few months, that is a completely reasonable call.

Does it need my bank login?

No. You sign in to your bank yourself, in your own tab, the way you always do. The extension reads the offers shown on that page. It never sees your username, password, balances or transactions.

Do I need the iPhone app?

No. The extension works on its own with an email sign-in. If you do have the app, the same email gives you one set of offers on both.

Does it track my browsing?

No. It runs only on your bank's own websites. On any other store site it does nothing until you click the icon, and it forgets the address as soon as it answers.

Is it free?

Yes. Adding your offers is free, which is the part the paid apps in this category charge for.

Does this work in Chrome on my iPhone?

No, and no extension does. Chrome on iPhone and iPad cannot run extensions at all, which is why the Chrome Web Store changes its button to "Add to Desktop" when you open it on a phone. On iPhone, browser extensions are a Safari feature, so RightCard's iPhone extension ships inside the app and runs in Safari. This Chrome extension is for Chrome on a computer: Mac, Windows, Linux or ChromeOS. Same account, same offers, either way.

What about Firefox and Safari?

Safari on iPhone already works, through the app. A Firefox build is next.
