Sync and stack credit card offers for maximum rewards. Compare point values across cards and find the best deals. Stop leaving money on the table. If you have credit card offers sitting in multiple bank portals, you're probably missing the best deal every time you shop. Reward Maximizer fixes that. The Problem Every major credit card has portal offers — Amex might give you 10% back at Nike while Chase gives you $15 cash back. But checking each portal separately before every purchase? Nobody does that. So you use whatever card is in your wallet and miss out. What Reward Maximizer Does It syncs your offers from Amex and Chase into one dashboard. Visit your card portal, click sync, and you're done. Now when you browse Nike.com, a banner appears telling you exactly which card to use and how much you'll save — no guessing, no tab switching. Stack for Even More Here's what most people miss: you can combine a card portal offer with a cashback site like Rakuten. Reward Maximizer flags these stacking opportunities automatically. Use your Amex for 10% back AND go through Rakuten for another 8%. That's 18% back instead of 10%. Real Dollar Comparisons "5x points" sounds great, but is it better than "3% cash back"? Reward Maximizer converts everything to cents per dollar using customizable point valuations so you can compare apples to apples. It marks the best deal with a BEST badge — no mental math required. Key Features - Sync offers from American Express, Chase, and Rakuten (more portals coming soon) - Automatic merchant alerts when you shop on sites with active offers - Smart stacking detection — see when card offers combine with cashback portals - Search, filter by category (dining, travel, gas, grocery, shopping), and view by merchant, card, or category - Export your offers as CSV or JSON - Fully customizable point valuations per card 💡 AFFILIATE DISCLOSURE Reward Maximizer includes referral links to Rakuten. If you sign up through our link, we may receive a small referral bonus at no cost to you. This does not affect which offers are shown or recommended — all offers are displayed and ranked based on value alone. Referral links are clearly labeled with a disclosure wherever they appear in the extension. 100% Private All data stays on your device. No accounts, no servers, no tracking.
