Wunu’ Smart Payment Optimizer – Chrome Extension
Never leave rewards on the table again.
Wunu’ instantly scans the cards you already carry and—right at checkout—tells you which one maximizes cashback, points, or promos for that specific merchant and purchase amount. No spreadsheets, no guess-work, no pop-ups to install at every bank site.
Why install Wunu’?
Real-time “best card” call-outs
Shop online or enter an amount in-store and Wunu’ flashes the optimal card within milliseconds, so you capture every boosted category, intro offer, or hidden merchant deal.
Automatic card intelligence
We keep millions of reward rules, quarterly categories, and issuer promos up-to-date for you—Chase 5×, AmEx offers, rotating Discover categories, even niche credit-union perks.
Personalized to your wallet
Wunu’ factors in your exact cards, spend caps, intro-bonus progress, and preference settings (e.g., “prefer travel points over cash”) for truly tailored recommendations.
Privacy first
Amounts are bucketed, merchants are hashed, and no full card numbers ever touch our servers. One-click analytics opt-out built in.
