Times have changed. Are you still confident you have the right tools?

Too many workflows still make investigators do the hard part manually - open it, watch it, listen to it, search for it, describe it, verify it, and work around whatever the tool does not show.

That is not a modern investigative workflow.

Semantics 21 tools are built for modern intelligence-led investigations - from victim identification and media review to CCTV analysis and transcription.

The excuses for staying with your outdated solution have officially expired.

Small visual details matter.

A partial badge, crest or logo can give investigators a starting point - but only if it can be assessed quickly and securely.

S21 School Badge Lookup helps teams search for possible school matches from limited badge detail, entirely offline and within the workflow they already use.

Use it as a standalone app or access the capability within S21 VisionX.
