Interrogation Video Analysis for Defense Teams

Every Interrogation Minute, Cited to the Exact Second

Evidence Copilot turns your interrogation footage, bodycam, jail calls, and discovery PDFs into timestamped, diarized transcripts with an AI evidence agent that answers with clickable citations — never legal conclusions.

The Interrogation Review Problem Facing Criminal Defense Teams

• Hours of custodial interrogation footage, no time to review it — Criminal defense attorneys juggle discovery review with everything else in a practice — court appearances, client calls, motion drafting — and the hours get eaten before a single hour of interview-room video gets watched frame by frame. A single felony case can drop many hours of bodycam, dashcam, and custodial interrogation footage into your discovery dump, all named like X13qrt9__x3455. Scrubbing that footage manually is non-billable work that directly erodes your realization rate — time that could go to the next client or the next motion.
• Report-vs-statement inconsistencies slip through when you're reviewing discovery fast — Police reports, Miranda timelines, and interrogation statements live in different files — and when you're pushing through a discovery review checklist at speed, a mismatch between the officer's report narrative and what your client actually said on camera is easy to miss. That's the exact gap impeachment material lives in: the report says consent was voluntary, the bodycam tells a different story. Every case, every file, the same risk — and losing it means losing the cross-exam question that could have broken the officer's testimony at the preliminary hearing or suppression hearing.
• Non-billable review work eats the practice — Marketing and admin are non-billable, and time spent scrubbing video is no different. With client acquisition costs climbing, every hour of unbillable footage review directly erodes realization and profitability. Solo defenders and public-defender offices feel it hardest: the choice is between reviewing the discovery properly and taking the next client. The free DIY stack — local Whisper plus NotebookLM — breaks at case scale: no diarization QC, no citations into the exact second, no redaction, no audit trail.

Why Defense Teams <span class="gradient">Choose Evidence Copilot</span>

• Cross-exam prep from quoted sources — Cross-exam prep from quoted sources: From a review signal with both sides' quotes — say, the officer's report narrative next to what the client said on the interview-room video — Evidence Copilot drafts suggested cross-exam questions, every question tied to a quoted source with a citation into the exact second of footage. No credibility conclusions, saved as attorney-review notes. You make every call; the tool just hands you the report-vs-bodycam mismatch with both quotes side by side.
• Suppression motion prep in one sweep — Suppression motion prep in one sweep: The Suppression Motion Prep playbook runs a consent, search-scope, stop-duration, K-9, and Miranda sweep across your actual bodycam and interrogation footage, then drafts a motion outline with both sides quoted and cited — grounded in your footage, not a template. Pair it with the Miranda Timeline playbook to build the chronological custodial-interrogation timeline, every entry linked back to the word-level transcript.
• Multi-camera sync without the guesswork — Multi-camera sync without the guesswork: Link bodycam, dashcam, and interview-room footage of one event to a single master clock for synced playback with an interleaved transcript. Auto-sync proposals are computed from word-timing correlation and reported with match evidence — like '31 word matches, ±0.2 s spread' — and never auto-applied. You review the proposal, accept it, and stop eyeballing timestamps across three players.

What's included

• Diarized transcription on Deepgram Nova with word-level timestamps and one-click speaker renaming that propagates across every segment of your interrogation footage.
• AI evidence agent chat with full-text search across transcripts and documents — answers grab video frames, extract clips, write timeline events, and email transcript excerpts, all with citations that seek the exact moment.
• Auto-signals on ingest compare every new file against earlier evidence in the case, surfacing candidate inconsistencies like statement-vs-call audio as unreviewed signals before anyone asks.
• Agent playbooks built for custodial-interrogation work: Suppression Motion Prep, Miranda Timeline, and Exhibit List Builder — each drafted from real quoted, cited sources.
• Frame-accurate redaction for video, audio, images, and PDFs — drag a rectangle, mute the exact spoken words — with originals never touched and every action audited.
• Exhibit pack exports bundle video clips, still frames, and quoted excerpts with a MANIFEST.md citation index, gated by per-member export permission.

Quick wins

• Use the per-case inbound email address: forward the discovery dump straight from the DA's email — bodycam, jail calls, 911 audio, scanned police reports — and it ingests every attachment, OCRs the scans, and diarizes the transcripts before you're back from court.
• Run the Exhibit List Builder playbook to draft an exhibit list tied to your real files — video clips, still frames, quoted excerpts — then export the exhibit pack with a MANIFEST.md citation index for hearing prep.

How it works

1. Upload the discovery dump — Drag in interrogation video, bodycam, jail calls, 911 audio, police reports, and scans — up to 2 GB per file by web upload, or just email attachments to your case's inbound address.
2. Get transcripts, signals, and a brief — Diarized transcripts with word-level timestamps, OCR'd document text, auto-signals flagging inconsistencies, and a one-click grounded case brief with evidence inventory, key moments, and follow-ups.
3. Build the motion and the cross — Run the Suppression Motion Prep or Miranda Timeline playbook, draft cross-exam questions from cited quotes, redact frame-accurately for discovery turnover, and export the exhibit pack with a MANIFEST.md citation index.

What clients say

The auto-signals caught a mismatch between the officer's report and what my client actually said on the interview-room video — the kind of thing I would have found at 11 p.m. the night before the suppression hearing, if I found it at all. The citation took me straight to the second. That's the whole job.

— Marcus Delgado

I ran the Miranda Timeline playbook on a four-hour custodial interrogation and had a chronological draft in front of me before lunch. Every entry linked back to the transcript with word-level timestamps, so when the supervising attorney asked where a statement came from, I clicked and we were watching it.

Redacting faces and muting exact spoken words for discovery turnover used to take a full day per batch of files. Now it's drag-a-rectangle, pick-the-words, and the original file is never touched — every redaction is a new derived file with an audit trail. That matters when turnover gets challenged.
