INSTRUMENTS & DATASETS

Eight web instruments, six browser extensions, one investigative toolkit.

Built by Signal & Shadow for open-source investigations. Each tool addresses a specific task in the workflow: source discovery, entity resolution, archival recovery, and chain-of-custody evidence handling, grouped by where it fits: research, investigation, or verification.
