Transparent working

Enable JavaScript for the interactive output. The method and limits remain readable below.

Method

Write the claim narrowly enough to check. Identify whether the source describes the exact product or a broader category. Record support separately from interpretation; the tool formats that record without opening the URL.

Example or interpretation

A package document might support a stated unit volume. It would not, by itself, establish a comparative health outcome. Keep those propositions in separate records.

Limits

A valid-looking URL is not proof. This tool does not verify documents, research quality or the truth of a claim.
