AI for Law Firms: Grounded Evidence Review for Criminal Defense Attorneys

Review the Whole Discovery Dump — With Citations to the Exact Second

Evidence Copilot turns bodycam video, jail calls, 911 audio, and police reports into timestamped transcripts and an AI evidence agent that answers your questions with clickable citations into the source moment.

The Discovery Problem Every Criminal Defender Knows

• The discovery dump lands all at once — with a preliminary hearing bearing down — A single felony case can mean 3,000+ pages of police reports, hours of bodycam and interrogation footage, 911 audio, and jail calls — and it all arrives in one drop, usually days before your prelim. The RAND National Public Defense Workload Study found the average murder case takes 248 hours to defend; life-without-parole cases take 286. Meanwhile the officer's report was written in an afternoon. Missing one buried fact — a Miranda warning that came late, a consent search that exceeded its scope, a 911 caller description that doesn't match the stop — can change your client's outcome. The material for your motion to suppress is almost always in there; finding it in the pile is the bottleneck.
• Caseload triage replaces diligent review — 'reasonably effective assistance' gets squeezed — Public defenders routinely carry 100+ cases, and the National Public Defense Workload Study concluded defenders are working roughly three times too many cases. Solo criminal defense attorneys juggle 30-50 active matters at once — arraignments, plea negotiations, collateral consequences conversations with clients, all competing with evidence review. The math doesn't work: something gets skimmed, and the skimming lands hardest on the longest evidence — bodycam dumps and jail-call archives. Too many cases get resolved without the Brady and Giglio review, the report-vs-footage comparison, and the impeachment digging they deserve.
• Flat fees turn every review hour into margin erosion — Under a flat-fee arrangement, every hour scrubbing bodycam footage or re-reading a supplemental report comes straight out of your margin — and across the aisle, the prosecution has teams of attorneys, investigators, and forensic experts. Thomson Reuters reports criminal defense attorneys reduce discovery review time by 63% using AI-powered tools, because the old way — a law clerk with a media player and a notepad — simply doesn't scale to 40 hours of footage per case. If review time can't be compressed, it gets skipped, and skipped review is how exculpatory evidence stays buried.

Why Criminal Defenders <span class="gradient">Choose Evidence Copilot</span>

• Impeachment material you can actually cite — Impeachment material you can actually cite. When a review signal flags a candidate inconsistency — the report vs the bodycam, the statement vs the jail-call audio — you get both sides quoted side by side. From there, cross-exam drafts give you suggested questions only, each one tied to a quoted source: the exact second of video or the exact page of the PDF. Click the citation, watch the moment, decide for yourself. No credibility conclusions are drawn — the judgment stays with you, and every draft saves as an attorney-review note you can hand to your second chair.
• Hours back on every case — Hours back on every case. Thomson Reuters reports criminal defense attorneys reduce discovery review time by 63% using AI-powered tools. Evidence Copilot gets you there with a workflow built for the dump: upload up to 2 GB per file — bodycam, interrogation footage, jail calls, 911 audio, scanned police reports — and get timestamped diarized transcripts and OCR'd document text. Full-text search across everything, one-click case briefs with evidence inventory and key moments, and an evidence agent that extracts clips, grabs video frames, and emails transcript excerpts with citations. Your investigator asks 'where does the officer say he found the bag?' and gets the answer with a deep link to the moment.
• Built for defense, with ethics rules in mind — Built for defense, with ethics rules in mind. Every AI output is marked AI-generated and pending human review — the product never makes legal conclusions. Redaction suggestions (bystander faces, minors, PII screens, license plates) file as cards marked 'AI-suggested — needs review' and are never auto-applied. Multi-camera sync proposals report their match evidence — like '31 word matches, ±0.2 s spread' — and never auto-apply. Originals are immutable; every action is audited; every redaction is a new derived file. When you turn over redacted discovery or prepare an exhibit pack, the chain stays clean.

What's included

• Diarized transcription with word-level timestamps — rename a speaker once and it propagates across every segment, so your bodycam and interrogation transcripts stay consistent.
• OCR that turns scanned police reports and photo evidence into searchable, citable text — with bounding boxes kept for later redaction.
• An AI evidence agent that searches across all transcripts and documents, grabs video frames, extracts clips, and answers with clickable citations into the exact source moment.
• Auto-signals on ingest: every new file is compared against earlier evidence, surfacing report-vs-bodycam and statement-vs-call inconsistencies as review signals before anyone asks.
• Multi-camera sync that links bodycam, dashcam, and interview-room footage to a single master clock, with sync proposals reported with match evidence and never auto-applied.
• Exhibit pack export — a zip of video clips, still frames, and quoted excerpts plus a MANIFEST.md citation index, gated by per-member export permission.

Quick wins

• Sync bodycam, dashcam, and interview-room footage of the same event to one master clock — synced playback with an interleaved transcript, and sync proposals reported with match evidence before you accept them.
• Run the Miranda Timeline playbook on custodial-interrogation footage to get a chronological timeline of the interrogation before your motion to suppress statements.

How it works

1. Create the case and drop in the dump — Start on the Solo plan or email [email protected] — the subject line becomes a new case and every attachment is ingested. Upload video, audio, PDFs, photos, and scanned documents up to 2 GB, or forward attachments to your case's dedicated inbound email address.
2. Let the workspace do the first pass — Files become diarized, word-level timestamped transcripts and OCR'd, searchable text. Auto-signals flag candidate inconsistencies between the police report and the bodycam, or a statement and a jail call, before you ask anything. Rename a speaker once and it propagates across every segment.
3. Ask, verify, and build — Ask the evidence agent questions and click through to the exact second of video or page of the PDF. Generate a grounded case brief, run the Suppression Motion Prep or Miranda Timeline playbook, draft cross-exam questions from quoted sources, and export an exhibit pack with a MANIFEST.md citation index.

How Evidence Copilot <span class="gradient">Grounds</span> Your Evidence Review

• Auto-signals compare every new file against earlier evidence in the case and surface candidate inconsistencies — report vs bodycam, statement vs call audio — before anyone asks.
• Agent playbooks like Suppression Motion Prep sweep consent, search scope, stop duration, K-9, and Miranda issues and draft a motion outline with both sides quoted and cited.
• Frame-accurate video redaction, word-level audio redaction, and PDF/image redaction — every redaction is a new derived file; originals are never touched and every action is audited.

What clients say

I forwarded the Axon link dump to the case email address and had diarized transcripts with word-level timestamps the same afternoon. When the officer's report says he gave the Miranda warning before the pat-down, I click the citation and watch the actual moment. That's the whole ballgame.

— Dana Whitfield

The auto-signals caught a discrepancy between the 911 audio and the supplemental report that I would have missed in the pile. It showed up as an unreviewed signal with both sides quoted — I verified it, then generated cross-exam questions each tied to the quoted source. My judgment still made the call; the citations made it fast.

— Marcus Bell

We run the Suppression Motion Prep playbook on every traffic-stop case. It sweeps consent, search scope, stop duration, K-9, and Miranda, and hands us a motion outline with both sides quoted and cited. Our investigators also love that redactions never touch the originals — every action is audited.
