AI Transcription for Lawyers: Bodycam

AI Transcription for Interrogation Footage, Bodycam Video, and Jail Calls

Upload the discovery dump and get timestamped, diarized transcripts of every interrogation, bodycam clip, and jail call — with an AI evidence agent that answers your questions and cites the exact second of video.

The Real Cost of Reviewing Interrogation and Bodycam Evidence by Hand

• Weeks of scrubbing interrogation and bodycam footage before you can even file — while discovery keeps piling up — Manual review and transcription of a typical case's video and audio can take days or even weeks, while big-city departments generate more than 10,000 hours of bodycam video per week. A single custodial interrogation can run three to six hours across multiple interview-room angles, plus the jail calls and 911 audio that come with it. By the time you've watched the full interrogation and located the Miranda moment, the preliminary hearing is already over and the voluntariness argument has slipped away.
• Police reports systematically understate what happened in the interrogation room — Research on interrogation reporting shows frequent errors of omission — officers' written reports understate use of confrontation, maximization and minimization techniques, leniency ploys, and false evidence claims. The maximization tactics ('we have your DNA') and minimization tactics ('this will go easier if you talk') that drive suppression and voluntariness arguments rarely make it into the report narrative. About one-fourth of wrongful conviction cases have included false confessions, and the interrogation techniques that produce them are exactly what the report leaves out — meaning the video is the only record that matters.
• Generic ASR breaks on interrogation audio — and diarization misses speakers — Wind, sirens, traffic noise, overlapping speakers, and multiple parties in interview-room and bodycam audio make interrogation footage notoriously hard to transcribe. AI speaker diarization struggles in exactly these scenes: it identifies only about two-thirds as many speakers as human-edited transcripts (3.3 vs. 4.8 per document), never detecting more than 7 speakers even when humans identify as many as 16. A verbatim transcript that mislabels the detective as the defendant — or drops a speaker entirely — is worse than no transcript at all when you're building a Miranda timeline.

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

• Find the Miranda moment without watching 6 hours of tape — Find the Miranda moment without watching six hours of tape. Upload the interrogation footage and jail calls, get timestamped diarized transcripts, and ask the AI evidence agent where custody began or what the detective promised — every answer carries a clickable citation that seeks the exact second of video. The Miranda Timeline playbook builds a chronological custodial-interrogation timeline for you, so the leniency pitch and the moment questioning turned custodial are minutes away, not a full weekend of scrubbing.
• Impeachment material that survives scrutiny — Impeachment material that survives scrutiny. When the police report says your client 'agreed voluntarily' but the bodycam shows maximization and minimization tactics, the auto-signals on ingest compare each new file against earlier evidence and surface the inconsistency as a review signal before anyone asks. The Suppression Motion Prep playbook drafts a motion outline — consent, search scope, stop duration, K-9, Miranda sweep — with both sides quoted and cited, and the cross-exam draft suggests questions tied to quoted sources. No credibility conclusions, no invented facts: your judgment stays yours.
• Published pricing that fits a defender's budget — Published pricing that fits a defender's budget. Solo is $39/user/mo with 15 media-processing hours included; Firm is $99/user/mo with 60 hours and a priority queue; PD Office is $750/attorney/yr with 100 hours — undercutting JusticeText (~$1,200/attorney/yr) by roughly Overage is metered and hard-capped at 3x included hours, so a runaway discovery dump can't overbill you. Every plan includes the full workspace — there are no feature tiers, no sales wall.

What's included

• Speaker-diarized transcription (Deepgram Nova) with word-level timestamps, so every interrogation question and answer is pinned to the exact moment it was spoken.
• AI evidence agent with full-text search across transcripts and documents — it reads transcript windows, grabs video frames, extracts clips, and writes notes, timeline events, and tasks.
• Auto-signals on ingest: every new file is compared against earlier evidence in the case, surfacing report-vs-bodycam and statement-vs-call inconsistencies as unreviewed review signals.
• Redaction built for defense workflows: drag-a-rectangle video redaction, word-level audio muting, and image/PDF redaction — every redaction is a new derived file and every action is audited.
• Case brief in one click: a grounded markdown brief with overview, evidence inventory, key moments, inconsistencies, and follow-ups.
• MCP server integration for Claude Desktop and Claude Code — query cases, search evidence, and pull citations read-only, with revocable tokens and full audit logging. No defense-side competitor has this.

Quick wins

• Sync bodycam and interview-room footage of the same interrogation to a single master clock with multi-camera sync — synced playback and an interleaved transcript make it obvious when the report narrative diverges from what the room camera captured.
• Use auto-signals on ingest to catch report-vs-bodycam contradictions before you even start review — every new file is compared against earlier evidence in the case and surfaced as an unreviewed review signal.

How it works

1. Upload the discovery dump — Drag in interrogation footage, bodycam video, jail calls, 911 audio, police-report PDFs, and photos — up to 2 GB per file by web upload or by emailing attachments to your case's inbound address.
2. Review transcripts and auto-signals — Get timestamped diarized transcripts with one-click speaker renaming, OCR'd document text, and auto-signals flagging candidate inconsistencies — report vs. bodycam, statement vs. call audio — before anyone even asks.
3. Ask, cite, and export — Ask the AI evidence agent anything; every answer carries citations into the exact second of video or page of the PDF. Generate a case brief, cross-exam drafts, or an exhibit pack with a MANIFEST.md citation index — all gated by per-member export permission.

How Evidence Copilot <span class="gradient">Turns Interrogation Footage</span> Into Citable Evidence

• Timestamped diarized transcripts of interrogation, bodycam, and jail-call audio — with one-click speaker renaming that propagates across every segment, so you can fix ASR speaker attribution errors once and move on.
• Auto-signals on ingest compare every new file against earlier evidence in the case, surfacing candidate inconsistencies — report vs. bodycam, statement vs. call audio — as unreviewed review signals before anyone asks.
• Cross-exam drafts generated from a review signal with both sides' quotes: suggested questions only, every question tied to a quoted source, saved as attorney-review notes.

Why we're different

• Timestamped diarized transcripts with one-click speaker renaming across every segment
• Every AI answer cites the exact second of video or page of the PDF
• Auto-signals compare new evidence against earlier case files on ingest
• Cross-exam drafts with both sides quoted — questions only, no conclusions
• Suppression Motion Prep and Miranda Timeline agent playbooks, shipped and tested
• Frame-accurate video and word-level audio redaction; originals never touched
• Multi-camera sync for bodycam, dashcam, and interview-room footage on one clock
• Published pricing with hard-capped overage; no sales wall

Built for US criminal-defense attorneys, law clerks, defense investigators, and public-defender offices — every AI answer cites the exact source moment it came from, and every plan includes the full workspace.

What clients say

I emailed the interrogation video and jail calls to the case address and had diarized transcripts the same day. When the report claimed my client 'agreed voluntarily,' the auto-signal flagged the bodycam segment that contradicted it — and the cross-exam draft gave me suggested questions with both quotes cited. I renamed the detective and my client once and it propagated across every segment.

The Miranda Timeline playbook rebuilt a custodial-interrogation timeline from three hours of interview-room footage in minutes. Every entry linked to the exact second, so I could pull the clip where the detective started the leniency pitch and show the minimization tactics the report never mentioned.

— Marcus Bellamy

I asked the agent where the officer first mentioned the search, got a citation to the exact moment, and exported an exhibit pack with the MANIFEST citation index for the suppression hearing. The multi-camera sync lined up the bodycam and interview-room footage on one master clock, so the timeline held up when I walked the judge through it.
