Code Four

Modernizing the police workflow.

Code Four slashes the administrative burden on law enforcement through AI-driven automation. Officers spend up to a third of their shifts manually transcribing body camera footage, creating inaccuracies, reducing transparency, and cutting into frontline duties. We're here to eliminate these inefficiencies by integrating with body cameras, record management systems, and digital evidence management systems—acting as a software layer for data processing. We free the most overworked and underappreciated people in the world: police officers.

TL;DR

We auto-generate reports, verify narratives, and surface evidence instantly — cutting desk time by 60% and putting officers where communities need them most.

👮‍♂️ The Problem

  • 40% of a typical shift vanishes to transcribing body-cam footage, filling forms, and locating clips across siloed systems.
  • Manual redaction and video scrubbing delay investigations, strain budgets, and erode public trust.
  • Departments juggle 8–10 incompatible software tools that weren’t built for today’s fast-paced operations

🚓 Our Solution – the Intelligence Layer for Digital Evidence

  1. Real-time transcription & summarization — every body-cam or interview video becomes searchable text + key-frame timelined.
  2. One-click redaction — faces, plates, minors’ voices, and PII are masked with CJIS-compliant logs.
  3. Context-aware search — ask “show me every time suspect #42 handled a weapon” and jump straight to the frames.
  4. Autofilled narrative reports that match your RMS schema and chain-of-custody rules.
  5. Plug-and-play integrations with leading body-cam vendors, evidence lockers, and CAD/RMS APIs—no rip-and-replace.

👥 Team

George Cheng, Dylan Nguyen, and Natnael Kahssay started Code Four inside their dorm rooms at MIT and dropped out to continue building the next generation of police tech. We’ve processed hundreds of videos and know every pain point from ride-alongs to record rooms.

🙌 Our Ask

  • Intros to Police, Sheriff, Transit, or University PDs that wrestle with video or paperwork overload.
  • Design-partner agencies (10–200 officers) willing to co-shape features.
  • We’ll fly anywhere in North America to set you up within 48 hours—no strings attached.
