Piecly is a free Chrome extension that compares your credit cards when you're checking out and shows which one earns the most — right before you pay.
Your cards earn different rewards depending on what you're buying. Piecly compares them all in real time and tells you which one pays the most.
It converts points, miles, and cash back into a single number — so you can see the real dollar value of each card on every purchase.
| Card | Earn rate | Point value | Effective | You'd earn |
|---|---|---|---|---|
| Amex Gold | 4× MR | 2.0¢/pt | 8.0% | $5.42 |
| Sapphire Reserve | 3× UR | 2.0¢/pt | 6.0% | $4.07 |
| SavorOne | 3% back | — | 3.0% | $2.03 |
| Double Cash | 2% back | — | 2.0% | $1.36 |
The Gold wins here because Amex points are worth more than cash back when used with travel partners. Piecly does this comparison instantly on every checkout page.
