Analyst's Notebook is a common used tool by digital analysts at law enforcement, military and other government intelligence agencies, or at fraud departments.

Several investigations, including an investigation into fraud in the U.S. Army, are reported to have used Analyst's Notebook capabilities.[1] It is also used by the Swedish police to analyse social contacts and social networks.[2]
