About Card Brain: Batch Add Credit Card Offers

Card Brain adds your eligible Amex, Chase, and Citi credit-card offers in one click instead of clicking each "Add to Card" button by hand. WHAT IT DOES • Scans the offers page you have open and finds every offer you can add. • Clicks each "Add" button for you, with a configurable delay between clicks. • Shows live progress so you can see what was added and stop at any time. • Works on Amex, Chase, and Citi offer pages — automatically picks the right handler based on the page URL. HOW TO USE 1. Sign in to your Amex, Chase, or Citi account in Chrome. 2. Open the offers page for the card you want. 3. Click the Card Brain icon and press "Add All Offers." 4. Watch the progress and press "Stop" any time you want. PRIVACY FIRST • Runs only on the tab you have open when you click the icon — never in the background. • Reads the page's offer buttons on your device, in your browser. Page contents are never sent to any server. • No analytics, no tracking, no third-party SDKs, no remote code. • The only network traffic is to our own server to verify your subscription. PRICING • 30-day free trial. No credit card required to start the trial. • $14.99 per year after the trial. Cancel anytime through the Stripe customer portal. NOT AFFILIATED with American Express, Chase, or Citi. This is a third-party productivity tool. Privacy policy: https://cardbrain-web.vercel.app/privacy Support: cardbrain.support@gmail.com
