Blotter records 6 LAPD and LASD scanner feeds 24/7, transcribes them with Whisper on a GPU, extracts locations and police codes, and plots each event on a map. The whole pipeline runs in about 5 minutes from dispatch to map pin. Tap any dot to read the transcript and play back the original audio. Search by keyword, time range, or police code. Covers all of LA County. Free, no account needed.

I got into listening to police scanners a while back. The Broadcastify app is great for live audio, but if you missed something, it's gone. And there's no way to see where things are happening on a map. So I built Blotter. It records 6 LAPD and LASD feeds around the clock, transcribes everything with Whisper, and tries to figure out where each dispatch is referring to. When it finds a location, it drops a pin on the map. The geocoding was the hard part. Dispatchers say things like "responding to Vernon and Central" and you need to know that's an intersection in South LA, not a person named Vernon. I went through a lot of iterations on the NLP before it stopped putting pins in random places. It all runs on one rented GPU. Poke around the map. If you spot a pin that's obviously wrong, let me know.
