Features
Everything you need to build, analyze, and present a case. Desktop-first, and your evidence stays local.
Map-first case workspace
Mapbox-backed satellite + dark style, 3D buildings, configurable location radius, crime scene locations, each piece of evidence at the exact spot it was recorded, distance measuring in feet and miles.
Every kind of evidence
Videos, photos, documents, audio recordings (911 calls and radio traffic), ALPR hits, and phone data. One import button takes mixed files, whole folders, or zip archives and sorts them by type, and a needs-attention view flags files missing a date, location, or recording type.
Watch how (0:47)Video tools & annotations
Frame-accurate annotations with subject tagging and object tracking, zoom framing, clip and stitch tools, built-in conversion (FFmpeg bundled), and DVR clock correction that preserves the true event time when a recorder's clock was wrong.
Watch how (0:41)Phone records on the map
Import call detail records and extraction GPS, see tower coverage sectors and phone activity alongside your other evidence, and follow a device through time with phone tracking mode.
Watch how (0:47)Presentation mode
Guided tours with synchronized 3D camera moves, chronological reveal, evidence clock, and per-subject route filtering. Share a read-only SAMM Player with prosecutors or partner agencies, no install required.
Watch how (0:44)Case overview
The whole case on one screen: an evidence strip at every location, subject focus, a time filter, and read-only quick view for briefings.
Watch how (0:32)Ready to present
A checklist of what is left before you present: videos that still need converting, evidence not yet verified against its fingerprint, items with no date, DVR clocks nobody checked. Each item has the button that fixes it, and anything marked not needed is recorded in the audit log.
Watch how (0:44)Errors that say what to do
When something fails, SAMM says what happened and what to do, with a button that fixes it where it can. A video that won't play says why: missing, damaged, needs converting. Ask Sam, the built-in helper, about any error in one click.
Timeline scrubbing
Cross-evidence timeline with cross-location chronology, subject-color routes, and clip-start / clip-end for video.
Private by design
Cases stay on the computer that owns them. Nothing about a case, not the evidence and not even its name or number, is stored on our servers. An append-only audit log records every change to a case, on that computer.
Security & data residency
How SAMM handles your evidence and what does and doesn't leave your machine.
Evidence stays local
SAMM is desktop-first. Evidence files (photos, videos, PDFs, annotations) live on your
computer in a private folder,
%LOCALAPPDATA%\SAMM Cases, or in a
folder your IT department sets.
Nothing about the contents of your evidence is uploaded to our servers.
What we store on Cloudflare
- Your account: agency, email, role, last-login.
- Signed-in computers: device name, OS, IP, timestamps.
- Feedback you submit (text only; screenshots are never stored).
- Update manifests + signed installer artifacts.
Nothing about your cases: no evidence, no case names or numbers, no lead detectives.
Authentication
Invite only: people join when their agency admin adds them, or with a code from us. Every sign-in uses a one-time code emailed to their work email, so there are no passwords to leak. Sessions are issued as Ed25519-signed tokens that the desktop app verifies locally.
CJIS posture
Because no case information is stored on our servers, the SAMM platform is designed to sit outside the CJIS evidence-handling boundary. We treat account data as sensitive and apply encryption at rest, TLS in transit, and audit logging for security-significant actions. Talk to us about your agency's specific compliance requirements.
