AmLaw 50 firm: 10× document-review throughput, partner-grade quality
An AmLaw 50 firm deployed xyner across litigation document review and contract due diligence — review throughput up 10×, with partner-grade quality maintained and full privilege protection.
What the customer was up against.
An AmLaw 50 firm was running massive document-review projects on litigation matters and M&A due diligence — work that consumed associate hours, frustrated clients who paid for it, and was increasingly contested on cost. Contract-attorney review centres mitigated cost but raised quality concerns. The firm needed a way to scale review without compromising attorney-client privilege or partner-grade output quality.
What xyner built.
Deployed xyner with three specialist agents — Document Review Agent, Privilege Screening Agent, Due Diligence Synthesis Agent — inside the firm's matter-management environment with full matter-scoped data isolation and privilege protection.
Measured impact.
Document-review throughput up 10× on agent-handled review; privilege screening accuracy materially improved; due-diligence synthesis cycle compressed from weeks to days on M&A matters; associate hours reallocated to substantive lawyering work.

What the deployment actually looks like.
Law-firm work carries unique data isolation requirements — privilege, work-product, conflicts. Every component of the deployment respects matter-scoped data boundaries.
Document Review Agent
Reviews documents against case-specific issue codes, responsiveness criteria and review protocols; produces partner-reviewable summaries and flagged concerns.
Privilege Screening Agent
Screens for attorney-client privilege, work-product and other protection categories; outputs are reviewed by attorneys before production.
Due Diligence Synthesis Agent
For M&A matters, synthesizes contracts, corporate documents, regulatory filings into deal-context summaries; surfaces material issues, change-of-control provisions and unusual terms.
Matter-scoped isolation
Each matter has its own data plane scope; cross-matter information flow is structurally impossible; conflicts boundaries enforced at the platform level.
Attorney workbench
Attorneys interact with agents from a single workbench integrated with the firm's document-review platform and matter-management system.
Privilege-grade audit
Every document touch, every agent action, every privilege determination captured; full audit trail defensible to courts and regulators.
How the rollout sequenced.
An 11-week pilot covered two matters (one litigation, one M&A) before phased rollout across practice areas.
Foundations & matter isolation
Deploy matter-scoped architecture; integrate with the firm's document-review platform and matter-management system; complete first round of privilege-protection review.
Agent configuration
Configure three agents against the two pilot matters; load matter-specific issue codes, review protocols and precedent into RAG.
Shadow mode
Agents review documents in shadow alongside contract-attorney teams; outputs reviewed by partners daily; thresholds calibrated by matter.
Pilot live
Live in two pilot matters with partner sign-off on every production; client communication coordinated with general counsel.
Practice-area rollout
Rollout across litigation and M&A practices; per-practice variations; per-client information governance reviewed.
Deposition prep + autonomy calibration
Deposition-prep agent introduced; autonomy thresholds calibrated by matter type and review category.
How the deployment is governed.
Law-firm AI carries unique governance: attorney-client privilege, work-product, conflicts, professional-responsibility rules and increasing court scrutiny of AI-assisted lawyering.
Privilege protection
Privilege screening is integrated into every document touch; any output that might cross a privilege boundary is gated for attorney review.
Matter isolation
Matter-scoped data planes; conflicts boundaries enforced at the platform level; cross-matter information flow is structurally impossible.
Attorney supervision
All agent outputs that reach clients or courts are reviewed and signed off by an attorney with the appropriate level of authority.
Court-disclosure readiness
The firm can produce, on request, complete records of which AI tools were used on which matters and how; aligned to the evolving court-disclosure landscape.
Professional-responsibility alignment
Deployment reviewed for alignment with the relevant professional-responsibility rules; ongoing monitoring as the regulatory landscape evolves.
Three transferable lessons.
Three lessons for other AmLaw firms considering agentic AI in core lawyering work.
Matter-scoped isolation is the foundational architectural choice
Without true matter isolation, privilege and conflicts concerns block adoption. With it, the platform unlocks scale without sacrifice.
Partner supervision must be visible, not just real
Partners signing off on every production isn't enough — the supervision must be visible in the audit trail. Court-disclosure requirements made this an upfront requirement.
Contract-attorney review centres are augmented, not replaced
Contract-attorney teams worked alongside the platform productively. The platform handled volume; contract attorneys handled nuance. Both quality and economics improved.
