Body-Worn Camera Analyzer
Upload BWC footage and let the pipeline transcribe audio, identify speakers, detect objects, build an event timeline, and flag inconsistencies — all with full chain of custody.
Starter includes upload and transcription. Essentials adds object detection, and Professional unlocks diarization, timeline, violation scan, and the full pipeline.
View plans →Automated analysis is a starting point for attorney review — not a substitute for professional judgment. All timestamps, transcripts, and flagged events must be verified before reliance in legal proceedings.

What the Analyzer Does
Whisper Transcription
Automatic speech-to-text using whisper.cpp. Timestamped word-level output synchronized with the video player. Supports noisy environments typical of field recordings.
Speaker Diarization
Identifies distinct speakers ("Officer A", "Subject B") and colors transcript segments. Critical for multi-party encounters where dialogue attribution matters.
YOLOv8 Object Detection
Frame-by-frame detection of people, vehicles, weapons, and objects. Bounding boxes with confidence scores, exportable as timestamped evidence exhibits.
Event Timeline Extraction
Reconstructs the chronological sequence of the encounter — approach, contact, commands, use of force, departure. Clickable timeline syncs with video playback.
Contradiction Detection
Cross-references the BWC transcript against police reports and other files in the case. Flags discrepancies in time, sequence, and claimed statements.
4th Amendment / Miranda Scan
Evaluates the encounter against constitutional standards — reasonable suspicion, probable cause, Miranda advisement timing, Graham v. Connor force factors.
