How your data is handled →A few useful answers
Before you
get started.
Is Spur free?
Yes. The assistant connector is free to use. No payment is required.
Do I need to add all my cards first?
No. Name the cards in your question. Saving a card list is optional.
Does Spur need my card number?
No. Spur compares card products, such as the card’s name and issuer. Do not enter a card number, security code, or bank password.
Does Spur make payments?
No. Spur recommends a card; you decide how to pay.
Which assistants can I use?
You can try Spur with a custom connection in Muse if your account supports secure credential entry and outbound MCP access. Our directory submission is still under review. Follow the connection guide; never send your key in chat.
Does every comparison include bonus rewards?
Reward coverage depends on the card and purchase. Spur labels missing rules and asks for facts that could change the result. Personal offers, credits and progress require your current information.
Will the estimate always match my statement?
Rewards depend on issuer rules, how the purchase is categorized, and your eligibility. Check any assumptions in the answer.
