Tell us what you would like to compare and which population the comparison should cover. A link to an original public dataset is especially helpful. Counts from a clearly defined group can support a tool; a viral claim without a source cannot.
For the current tools, the methodology explains how counts, ranks and missing data are handled. Website and analytics details are on the privacy page.
