# Code Four

> Code Four builds AI software for law enforcement: AI police report writing from body-worn camera video, investigation software, redaction for public records release, and a mobile field app. Every report fact links back to its source clip and timestamp, and officers review and approve every report.

Founded by George Cheng and Dylan Nguyen. Works with any body camera system and the records and dispatch systems agencies already run.
