Audio Evidence Analysis for Criminal Defense

Every Word of Discovery, Cited to the Exact Second

Evidence Copilot turns bodycam, 911 calls, jail calls, and interrogation audio into timestamped, diarized transcripts with an AI evidence agent that answers your questions with clickable citations — built for criminal-defense teams, defense-only by design.

Why Discovery Review Is Breaking Defense Teams

• Caseloads force triage, not diligence — the 1973 NAC standard says 150 felonies per defender per year — The National Advisory Commission on Criminal Justice Standards and Goals capped public defender caseloads at 150 felony or 400 misdemeanor cases per year back in 1973 — and real caseloads routinely exceed those numbers today. When every case can't get full attention, evidence review is what gets triaged first: bodycam goes unwatched, jail calls go unreviewed, and the report-vs-statement inconsistency that wins a suppression motion stays buried. Digital discovery keeps growing — 40+ hours of media per felony case is now common — so manual review at scale is mathematically impossible. Attorneys need a workflow that makes diligence on every case feasible, not a choice between which client gets it.
• Digital discovery eats the week — 40+ hours of bodycam, 911 audio, and jail calls per felony case — A single felony case can arrive with 40+ hours of media: bodycam files with names like X13qrt9__x3455, interrogation-room footage, 911 calls, jail calls, plus scanned police reports with no text layer. Reviewing that manually means scrubbing video in real time, re-listening to audio to confirm who said what, and retyping passages from PDFs so you can cite them. Every hour spent hand-scrubbing is an hour not spent on hearings, filings, or client contact — and the volume grows with every new case. The result is the industry's baseline: lawyers rank among the highest-burnout professions, and manual evidence review is a major driver of the overload.
• Burnout is the industry baseline — High caseloads and heavy workloads put lawyers among the professionals most at risk of burnout, depression, and anxiety — and manual evidence review is a major driver of the overload.

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

• Find the impeachment moment in minutes — Find the impeachment moment in minutes, not days. Upload the discovery dump — bodycam, interrogation footage, jail calls, 911 audio, scanned police reports — and get timestamped diarized transcripts with word-level timestamps plus OCR'd text from every scanned document. Then search full-text across everything: ask where the officer's timeline in the report diverges from the bodycam, and the AI evidence agent answers with a citation that seeks the exact second of video or page of the PDF. Grab video frames, extract clips, and build cross-exam drafts where every suggested question is tied to a quoted source — no credibility conclusions, attorney-review notes only.
• Reclaim hours every week — Reclaim 6–10 hours every week with grounded automation. One-click case briefs assemble the overview, evidence inventory, key moments, inconsistencies, and follow-ups. Agent playbooks do the sweeps you'd otherwise do by hand: Suppression Motion Prep runs the consent/search-scope/stop-duration/K-9/Miranda analysis and drafts a motion outline with both sides quoted and cited; Miranda Timeline builds the chronological custodial-interrogation timeline; Exhibit List Builder ties a draft exhibit list to real files. Auto-signals compare every new file against earlier evidence and surface candidate inconsistencies — report vs bodycam, statement vs jail call — before anyone thinks to ask.
• Ethics-first by design — Ethics-first by design, built for attorneys bound by the Rules of Professional Conduct. Every AI answer cites the exact source moment it came from and is marked AI-generated, pending human review — the product never makes legal conclusions. Originals are immutable; every redaction is a new derived file with a full audit trail. Frame-accurate video redaction, word-level audio redaction, and image/PDF redaction handle discovery turnover, with AI-suggested regions (faces, PII screens, license plates) filed as suggestion cards that require your review — nothing is ever auto-applied. Published pricing with no sales wall: Solo $39/user/mo, Firm $99/user/mo, PD Office $750/attorney/yr — every plan includes the full workspace.

What's included

• AI evidence agent with full-text search across transcripts and documents — every answer carries a clickable citation that seeks the exact video moment, and it can extract clips, write notes, timeline events, and tasks.
• Deepgram Nova transcription with speaker diarization and word-level timestamps, plus one-click speaker renaming that propagates across every segment of the case.
• OCR turns scanned PDFs with no text layer and photo evidence — receipts, exhibits, screenshots — into searchable, citable text, with bounding boxes kept for redaction.
• Agent playbooks like Suppression Motion Prep sweep for consent, search-scope, stop-duration, K-9, and Miranda issues and draft a motion outline with both sides quoted and cited.
• Manual, frame-accurate redaction for video, audio, images, and PDFs — every redaction is a new derived file, originals are never touched, and every action is audited. AI-suggested regions file as review cards, never auto-applied.
• Exhibit pack exports bundle video clips, still frames, and quoted excerpts with a MANIFEST.md citation index, gated by per-member export permissions.

Quick wins

• Use the per-case inbound email address: forward the discovery dump straight from the prosecutor's email — [email protected] creates a new case from the subject line and ingests every attachment automatically.
• Run the Exhibit List Builder before the pretrial conference — a draft exhibit list tied to real files beats rebuilding it from memory the night before.

How it works

1. Upload the discovery dump — Drag in bodycam, interrogation footage, 911 and jail calls, police report PDFs, photos, and scans — up to 2 GB per file, or email attachments straight to your per-case inbound address.
2. Review grounded transcripts and signals — Get diarized, word-level timestamped transcripts, OCR'd document text, and auto-signals flagging candidate inconsistencies — report vs bodycam, statement vs call audio — as unreviewed cards.
3. Build the motion and the cross — Ask the AI agent questions with clickable citations, draft cross-exam questions tied to quoted sources, run the Suppression Motion Prep playbook, and export an exhibit pack with a citation manifest.

What clients say

The auto-signals caught a report-vs-bodycam inconsistency on ingest — the officer's narrative said consent to search, the bodycam told a different story. The citation jumped me straight to the exact second of footage. I would have found it, maybe, three days into manual review. On my caseload, three days is a luxury I don't have.

— Marcus Delgado

The Suppression Motion Prep playbook swept the consent, search-scope, stop-duration, and Miranda issues and drafted the outline with both sides quoted and cited. My law clerk verified every quote against the source in an afternoon instead of a week. Every question in the cross-exam draft tied back to a quoted source — that's the only way I'll trust AI output.

— Sarah Whitfield

With our caseloads, we can't hand-scrub every jail call anymore — the 1973 NAC standards were exceeded a long time ago. Diarized transcripts with word-level timestamps and the Miranda Timeline playbook changed our intake review. And at $750 per attorney per year with 100 processing hours included, it fit a public-defender budget without a procurement fight.
