About Spur

A clearer choice.
Before you pay.

Choosing a card should not mean memorizing every rewards rule. Spur helps compare the card products you name and explain the rewards math.

Start with the cards you have.

The assistant connector is free to use. No bank connection, card numbers or travel goal is required. Name your cards and the purchase you’re considering. Saving a card list is optional and takes your explicit instruction.

The assumptions matter.

Eligibility, bonus limits and the way a purchase is categorized can change an estimate. Check the assumptions in a comparison and confirm the terms that apply to your card. Spur does not make payments for you.

Getting connected.

Our Muse directory submission is still under review. You can try a custom connection if your Muse account supports secure credential entry and outbound MCP access. Create a free account, copy the setup prompt from our guide, and enter your key only through the secure credential flow. Never paste a key into chat.

Looking for the iOS app?

The app is a separate project. Existing waitlist and beta-request paths remain available; the free connector does not require an app download.
