CardCompass — Rewards Optimizer by Carlo

CardCompass shows which credit card in your wallet earns the most rewards on every site you visit — automatically, as you browse.

How it works: Add your cards once, then CardCompass tracks 260+ merchants across shopping, dining, gas, travel, groceries, and more. When you're on a supported site, the extension shows your top card
and the exact rewards rate, so you never leave money on the table.

Free features:
- Top card recommendation for every supported merchant
- Your go-to cards for everyday categories (dining, shopping, gas)
- Monthly visit tracker

Pro ($5/mo): Full ranked wallet, gap analysis showing where better cards exist, and direct apply links.
