TRANSCRIPT
LIVE DISPATCH, MAPPED

A live police, sheriff & fire scanner. Calls are transcribed as they're spoken and pinned on the map in real time.

  2. Set your zone — search an address or tap the map — to get alerted when a call drops nearby.
  3. Search & filter calls, streets and units anytime.

Not an official source. Audio is delayed and AI transcription can be wrong — don't rely on it for emergencies. Call 911 for real emergencies.

  3. Paste it here:
Your key is saved only in this browser and sent only to Groq. Each call is transcribed in about a second.
BROADCASTIFY FALLBACK PLAYER

Use this player if the main audio is blocked. Transcription keeps working in the background either way.

ADD TO HOME SCREEN · OPTIONAL

Totally optional. The site works in your browser. Installing just adds notifications and makes it open like an app.

Add Cop Feed to your home screen for reliable background audio and alerts. It runs like a real app and keeps notifications working.

Notifications are opt-in and per-device, and you can turn them off any time in your settings.
