CHECKOUT · EXTENSION

Be there when they pay

ChatGPT can't pop up on Amazon checkout. This extension opens a side panel with your wallet ranking — you never leave the merchant tab.

Install from the Chrome Web Store

Add CardWise to Chrome → One click, free, no bank login. The side panel ranks your synced wallet inline (no stuck loading screen), with right-click, ⌘⇧K, and an earn-rate badge on the toolbar.

Deep links (Shortcuts / Siri / bookmarks)

Skip the extension entirely with a URL like:

/?q=$47%20Whole%20Foods
/embed?q=$320%20ShopRite
/?m=Chipotle&a=18

Set up mobile + Siri → · Privacy

Developer: load unpacked

Clone the repo and open the extension/ folder.
Open chrome://extensions, enable Developer mode, Load unpacked.
Optional: set a local base URL in extension options (http://localhost:3000). Store builds only call production for /api/pick.

Your wallet stays on CardWise (browser storage / account) — the extension only opens the pick. No bank logins. Free forever.
