Where answers come from
How Miles finds an answer
Miles checks four sources in order: its maintained card data, your wallet, a points-and-miles reference library, and the open web when needed.
The status line names the source Miles is checking. When an answer requires several tools, the line cycles through them.
Four sources, in order
Miles checks its maintained card data first. It covers fees, earning rates, credits, transfer ratios, elite tiers, and current sign-up bonuses. The data is checked daily, and changes reach answers within minutes.
Miles then checks your wallet for the cards you hold, your point valuations, credits you have used, and benefits that are expiring. If information is missing, Miles asks instead of filling in the gap.
Its reference library covers questions that structured card data cannot answer, such as how an award chart works, what changed after a devaluation, or whether a strategy still applies. This material informs the judgment in the answer.
Miles uses the open web last. It is useful for time-sensitive facts that are not in the dataset or reference library, such as lounge hours or a new promotion. Miles searches the web when the library has no relevant result or when you request a specific source.
Card data is current by default
You do not need to add “check the latest” or “search for current offers” to a question about card facts. Miles reads those from its maintained card data whatever the phrasing, so the request does not change where the answer comes from. Adding it would not help: for card facts the open web is the weakest source Miles has, and the dataset is already current.
Fees, earning rates, credits, transfer ratios, and live sign-up bonuses are current by default. Ask for the card fact you need.
When Miles searches the web
Ask about information outside the dataset, such as opening hours, an event, or a recent announcement. Miles searches the web when its other sources do not contain the answer.
You can also name a source. Miles can restrict a search to one publication and report what that source says.
See which source Miles is checking
While Miles works, the status line shows the current action: looking up a card, searching the reference library, or searching the web. When an answer requires several tools, the line cycles through them.
Miles does not show its raw reasoning. That output can include internal tool and data-source names that do not belong on a public surface. The status line shows the source being checked without exposing those details.
