Brainside picks · RewardsNotifier delivers
Never Miss a Credit Card Reward Again
We run the brainside: matching merchants, categories, and your Vault so the smartest swipe is calculated before you finish checking out. RewardsNotifier is the thin utility—in-page nudges, sync from your dashboard—not a stitched-together mash of outsider feeds calling the shots for you.
Brainside × utility
Reasoning stays with us—the Vault intelligence and payout logic. RewardsNotifier is how that shows up fast and quietly while you browse.
Smart Detection
Brainside categorizes merchants in real time and lines them up against the Vault rules for the cards you actually linked—nothing retrofitted off another company’s guessing engine.
Privacy First
We never store your full card numbers or CVVs. Your sensitive financial data stays secure on your device.
Reward Optimization
Comparisons stay inside your Vault: our maintained earn rules against the cards you linked—no opaque middleman engine picking winners for you.
Personalized Insights
See uplift when you follow the sharper pick—attribution stays tied to what you opted into in RewardsNotifier, not a rented scoreboard from somewhere else.
Brainside Vault · RewardsNotifier in the wild
We steward the Vault: reward categories and card metadata stay current against issuer-published terms. That brainside layer is ours—rates, rules, refreshed on our timeline. RewardsNotifier—the extension plus dashboard—is only the courier: it flashes the pick at checkout using that same Vault. No legacy rewards-exchange pipe, no borrowed stack calling the swipe for you.
Your Cards, Maximized
Mark what you truly carry—the Vault aligns those tiers with brainside picks when you checkout
The Vault keeps growing—we fold new programs in centrally so you aren't stitching together scavenged spreadsheets and hearsay lists
Explore product featuresHow RewardsNotifier Works
Brainside does the comparisons; RewardsNotifier flashes the cue at checkout
1. Add Your Cards
Link the cards you really use from the RewardsNotifier dashboard—we never ask for PANs. Brainside knows the Vault structure; you flip on what matters to you.
2. Browse Normally
Keep your habits. RewardsNotifier stays quiet until brainside spots a better-earning card you already linked—then the utility surfaces the nudge.
3. Get Notified
RewardsNotifier pings when brainside modeling says another linked card earns more—it's lightweight UI, still our logic underneath.
