1,500 pages of discovery. The inconsistency is on page 847. Find it in minutes.
Upload the entire discovery production. Vaquill AI reads across police reports, witness statements, lab results, and cell phone extractions to surface inconsistencies, build chronologies, and draft suppression motions with inline citations to both your evidence and the case law. Every answer verified before you see it.
The pain points AI actually solves in criminal defense.
Not hypothetical. These are the bottlenecks criminal defense lawyers hit every week.
Discovery volume has exploded with digital evidence
A single cell phone extraction produces 5,000+ pages of texts, call logs, GPS data, and photos. Body-cam footage from a routine DUI stop runs 2 to 4 hours across multiple officers. Prosecutors dump thousands of pages and call it "open file" discovery. The exculpatory needle is in a digital haystack, and the practical burden falls on defense counsel to find it.
Inconsistencies hide between documents, not within them
The officer's written report says one thing, the body-cam shows another, and the 911 caller described something different. Effective suppression motions and cross-examinations are built on these inconsistencies, but finding them requires comparing multiple documents line by line. With 100+ open cases, appointed counsel cannot do this manually for every case.
Fourth Amendment law is hyper-fact-specific and rapidly evolving
Post-Carpenter (2018), digital search law changes every term. Geofence warrants, keyword warrants, social media warrants, and AI-generated evidence create new issues faster than treatises can cover them. Each circuit has its own interpretive gloss on Terry stops, the automobile exception, and consent searches. You need the case that matches your specific fact pattern in your specific jurisdiction.
No tool for sentencing comparables
Civil litigators have verdict databases. Transactional lawyers have deal databases. Criminal defense lawyers negotiating pleas rely on experience, word of mouth, and informal networks to answer "what sentence did a similarly situated defendant receive for this offense in this courthouse?" Newer lawyers and those handling unfamiliar charge types are at a significant disadvantage.
Appointed counsel carry 2 to 4x recommended caseloads
NAPD and ABA standards set maximum recommended caseloads. Most appointed counsel exceed them by 2 to 4x. With 100 to 200+ open cases, the triage problem is acute: which cases need a motion this week? Which discovery has not been reviewed? Which plea deadlines are approaching? AI-assisted triage and document review is not a luxury; it is a necessity for constitutionally adequate representation.
Brady material buried in volume
The prosecution's duty to disclose exculpatory evidence (Brady v. Maryland, 373 U.S. 83) does not mean they highlight it. Courts have held that "open file" policies do not relieve the prosecution of Brady obligations (Strickler v. Greene, 527 U.S. 263), but when exculpatory evidence is scattered across 5,000 pages, the defense lawyer must find it.
Your criminal defense workflow, with AI at every step.
Arraignment and bail
Assess charges, criminal history, flight risk, and community ties within hours. Argue bail based on local bail schedules, judge tendencies, and relevant bail reform statutes. Appointed counsel often meets the client for the first time at this hearing.
AI research: bail statutes and recent rulings in your jurisdictionDiscovery upload and review
Receive the discovery dump: police reports, supplemental reports, lab results, witness statements, cell phone extraction summaries, and body-cam transcripts. Organize, read, and identify what matters across hundreds to thousands of pages.
upload everything, ask questions across the full production, get cited answersFind inconsistencies across documents
Compare the officer's written report against the body-cam transcript against the 911 call log. Surface contradictions in testimony, timeline gaps, and factual discrepancies that form the foundation of suppression motions and cross-examination.
Document chat: "What inconsistencies exist between Officer Martinez's report and the body-cam transcript?"Motion to suppress
Draft the motion matching your specific facts to the constitutional standard. Fourth Amendment suppression motions are the most fact-intensive motions in criminal practice. The motion must connect the factual inconsistencies in the evidence to the legal standard in your jurisdiction.
AI drafting grounded in both your uploaded evidence and case law researchBrady and Giglio motions
Identify potential exculpatory and impeachment material in the discovery production and draft motions to compel disclosure of material the prosecution has withheld.
Document chat: "What evidence in these records could be exculpatory or impeaching?"Plea negotiation
Evaluate the offer against sentencing guidelines, prior record scoring, mandatory minimums, and collateral consequences (immigration under Padilla, sex offender registration, firearm disability, professional licensing). Research comparable sentences for similarly situated defendants.

Specific criminal defense workflows, not generic AI promises.
Discovery upload to suppression motion
Upload 1,500 pages of discovery: police reports, supplemental reports, lab results, witness statements, and cell phone extraction summaries. Ask Vaquill AI to identify inconsistencies between the officer's written report and the body-cam transcript. Then draft a motion to suppress with inline citations to both the discovery documents (with PDF page highlights) and the relevant Fourth Amendment case law in your circuit. What takes 8 to 12 hours manually compresses to under an hour.
Post-Carpenter digital search research
Ask Vaquill AI how your circuit has ruled on warrantless cell phone searches after Carpenter v. United States (585 U.S. 296). Get answers with inline citations to the court PDFs. Set up keyword alerts for new digital search decisions in your circuit, delivered via Slack or Telegram when a relevant opinion drops.
Fourth Amendment citation graph
Trace the evolution of the automobile exception from Carroll v. United States through its modern applications, including Collins v. Virginia (584 U.S. 586, 2018, holding the exception does not extend to a vehicle parked in a private driveway). See which recent cases cite and distinguish the doctrine, identify circuit splits, and find the most persuasive authority for your specific fact pattern.
Chronology builder from incident reports
Upload the incident report, supplemental reports, body-cam transcripts, 911 call logs, and CAD dispatch records. The chronology builder auto-generates a timeline of events. Immediately spot gaps: the 14-minute gap between dispatch and body-cam activation, the inconsistency between the reported time of the stop and the 911 call timestamp. These gaps become the factual foundation of the suppression motion.
Plea agreement review and collateral consequences
Upload the proposed plea agreement into Vaquill AI. Ask: "What collateral consequences flow from a guilty plea to this offense?" Get answers covering immigration consequences (Padilla v. Kentucky), sex offender registration (SORNA), firearm disability (18 U.S.C. 922(g)), and professional licensing impact. Cross-conversation memory means Vaquill AI remembers the client's case details across sessions.
Built for the law you actually practice.
Vaquill AI understands these criminal defense concepts when you research, draft, and verify.
Fourth Amendment: Terry stops
Terry v. Ohio (392 U.S. 1, 1968): reasonable suspicion standard for investigatory stops and protective frisks. The fact-specific application varies by circuit.
Carpenter v. United States (585 U.S. 296)
Cell-site location information requires a warrant. The landmark digital privacy case that reshaped Fourth Amendment analysis for all digital evidence.
Riley v. California (573 U.S. 373)
Cell phone searches incident to arrest require a warrant. Changed every traffic stop and arrest where a phone is involved.
Brady v. Maryland (373 U.S. 83)
The prosecution must disclose exculpatory evidence to the defense. Violation is grounds for reversal regardless of the prosecution's good or bad faith.
Giglio v. United States (405 U.S. 150)
Extends Brady to impeachment evidence. Prosecution must disclose material affecting witness credibility, including cooperation agreements and criminal history.
Strickland v. Washington (466 U.S. 668)
Two-prong test for ineffective assistance of counsel: deficient performance below objective standard of reasonableness, plus prejudice (reasonable probability of a different outcome).
Crawford v. Washington (541 U.S. 36)
Confrontation Clause requires cross-examination of testimonial hearsay. Lab reports, forensic certificates, and 911 calls may be testimonial.
Padilla v. Kentucky (559 U.S. 356)
Defense counsel must advise on immigration consequences of a guilty plea. Failure to do so constitutes ineffective assistance. Extended by lower courts to other collateral consequences.
Daubert / Frye for forensic evidence
Daubert (509 U.S. 579) and Frye (293 F. 1013) govern admissibility of forensic evidence. DNA mixture interpretation, ballistics, and digital forensics are increasingly challenged.
Federal Sentencing Guidelines (USSG)
Advisory after Booker v. United States (543 U.S. 220, 2005). Base offense levels, specific offense characteristics, criminal history categories, departures, and variances.
Franks v. Delaware (438 U.S. 154)
Defendant can challenge the truthfulness of a warrant affidavit. If deliberate falsehoods or reckless disregard for truth is shown, the warrant may be voided.
Collateral consequences
Immigration removal (Padilla), sex offender registration (SORNA), firearm disability (18 U.S.C. 922(g)), professional licensing, housing barriers, and employment restrictions. Effective plea counseling requires understanding all of them.
How the criminal defense AI landscape looks today.
An honest look at who else serves criminal defense lawyers with AI, and where Vaquill AI fits.
Matey
Austin-based, $7.5M seed (2024). Specializes in criminal defense discovery: video, audio, and text evidence analysis with AI-powered transcription and inconsistency flagging. Targets public defender offices. Pricing is not public but reportedly targets institutional buyers. Narrower than a full research/drafting platform: Matey is a discovery tool, not a legal research tool.
Paxton AI
General legal AI with a criminal law page. Offers case law research with AI-generated answers citing real cases. Does not appear to offer discovery document analysis, evidence review, or criminal-defense-specific workflows like suppression motion drafting from uploaded evidence. $499/month Individual plan.
Clearbrief
Brief-writing and citation-checking tool. Relevant for criminal appellate work and verifying that motion citations are accurate. Not a criminal-defense-specific tool: no discovery review, no evidence analysis, no criminal-specific workflows. A complement, not a competitor, for the discovery/research piece.
Public defender tech landscape
No dominant national solution exists. Large PD offices (LA, Bronx Defenders, Colorado) have built internal tools. NAPD and NLADA advocate for tech investment but do not build software. The gap between prosecution tech (funded by law enforcement budgets) and defense tech remains wide.
Vaquill AI (where we fit)
The combination no competitor matches: 100-document chat for discovery review with inline citations and PDF highlighting, AI legal research grounded in case law, motion drafting from your evidence, citation graphs for constitutional doctrine, chronology builder from incident records, shareable research links for co-counsel, and Slack/Telegram alerts. Transparent per-seat pricing, not per-case.
Criminal Defense lawyers ask us
Can Vaquill AI handle cell phone extraction reports and police reports?
Yes. Upload Cellebrite/GrayKey text exports, police reports, supplemental reports, lab results, and witness statements as PDFs or text files. Vaquill AI ingests thousands of documents per matter and lets you ask questions across the entire production. Every answer cites the exact page and passage in the source document with highlighting.
Does Vaquill AI handle body-cam video or audio?
Vaquill AI currently handles text documents, not raw video or audio files. If you have body-cam transcripts (text), those are fully supported. For raw video and audio analysis, tools like Matey specialize in that. You can use both: Matey for video/audio, Vaquill AI for the text discovery, research, and motion drafting.
How does Vaquill AI help with Fourth Amendment research specifically?
The citation graph lets you trace how any Fourth Amendment doctrine (Terry stops, automobile exception, digital searches post-Carpenter) has been applied in your specific circuit or state. See which cases cite the standard, how courts have ruled on your fact pattern, and identify the most favorable precedent. Keyword alerts monitor for new Fourth Amendment opinions in your jurisdiction.
Can I use this for plea negotiation?
Yes. Research sentencing outcomes for similar charges in your district. Upload the proposed plea agreement and ask about collateral consequences (immigration, SORNA, firearm disability, licensing). Cross-conversation memory means Vaquill AI remembers your client's details across sessions without re-uploading.
Is client data secure? Criminal cases involve the most sensitive information.
AES-256 encryption at rest, TLS 1.3 in transit, US data residency on AWS, full tenant isolation, and a contractual commitment to never train models on your data. We treat your client's data with the same seriousness you do. Aligned with SOC 2 controls. See /security for the complete posture.
Is this affordable for appointed counsel and public defenders?
Vaquill AI starts at a transparent per-seat price for a solo. No per-case fees, no per-GB storage charges. For institutional public defender offices, contact us for volume pricing. We believe effective defense counsel should not depend on the defendant's ability to pay, and our pricing reflects that.
Find the inconsistency. Draft the motion. Cite the law.
Upload discovery, surface contradictions across police reports and witness statements, draft suppression motions with inline citations, and trace Fourth Amendment doctrine with a citation graph, all in one platform.
