Features

Simple, but
really smart.

Instant answer

Open the app. It tells you which card to use.

No math. No guessing. Slate compares every card in your wallet and shows you the winner instantly.

Deep rewards logic

Works for specific stores, not just broad categories.

Slate knows your Amex Gold earns 4x at restaurants — not just a generic dining rate. The details matter.

Zero friction setup

Pick the cards you own. Done. No bank linking, ever.

Choose from our library of popular rewards cards. That's the whole setup. Your data never leaves your phone.

100% private

Stop paying with the wrong card and losing money.

The average rewards holder misses hundreds of dollars in points every year. Slate makes sure that never happens again.

The builder

Hi, I'm Leon 👋

I built Slate because I was tired of leaving points on the table every time I paid for something. No complexity, no bank linking, no subscription. Just the answer, right when you need it.
