Credit Card Optimizer

“Before Clyne, I was just guessing which card to use. Now I get notified the moment I walk into a store—it’s like having a personal rewards advisor in my pocket.”

Amara Thomas

Frequent Traveler

“Clyne helped me rack up an extra 10,000 points in a month just by switching which card I used for groceries and gas. The Chrome extension is great for shopping flights too.”

Frequently asked questions

How does Clyne know which card is best?
Clyne uses your cards’ reward structures, merchant categories, and location data to recommend the card that will earn you the most rewards—cashback, points, or miles.
Is my data safe with Clyne?
Yes. All card data is encrypted, never shared, and only used to provide recommendations. Clyne follows industry security best practices.
Will Clyne work for online shopping?
Absolutely. Our Chrome extension activates at checkout and shows you the best card to use based on the merchant and your rewards.
What if I don’t know my card’s rewards?
You don’t need to—we track and update that info for you automatically, so you’re always getting the latest advice.
Does Clyne cost anything?
Clyne is free during beta. We’ll introduce premium features later, but the core recommendation engine will always have a free tier.
Will Clyne work if I have multiple cards from the same bank?
Yes. Clyne understands the differences between each card—even from the same bank.
