GenAI in Legal Workflows: How HaystackID® Is Operationalizing AI for DSARs, Privilege Review, and Regulatory Response in 2026

HaystackID Blog | March 18, 2026

Editor’s Note: Generative AI (GenAI) is no longer a future concept for legal teams; it’s becoming part of how real work gets done. The conversation has shifted from exploration to execution, with a growing focus on applying GenAI in a controlled, defensible, and regulatory-compliant manner. In this article, Scott Sterkel provides a practical look at how HaystackID is integrating GenAI into core legal workflows, including Data Subject Access Request (DSAR) response, privilege review, and regulatory matters. Rather than focusing on theory, the piece highlights real-world application, including a large-scale privilege log completed under significant time pressure. Sterkel emphasizes a critical point: GenAI delivers value when paired with human oversight and strong governance. As organizations plan for 2026, the focus is shifting toward production-ready workflows that can withstand scrutiny.

The conversation inside corporate legal departments has shifted. Teams aren’t asking whether to use GenAI in legal workflows anymore — they’re asking how to do it defensibly, at scale, and in a way that holds up under scrutiny. That shift is the backdrop for everything HaystackID is building heading into 2026.

Through our recent acquisition of eDiscovery AI, HaystackID has expanded its GenAI capabilities significantly — and those capabilities are already producing measurable outcomes for corporate legal teams facing the trifecta of growing data volumes, compressed timelines, and heightened expectations around governance.

The Proof Point: 230,000 Privilege Log Entries in Eight Business Days

Results matter more than promises, so let’s start with a concrete example.

In a recent regulatory matter, HaystackID supported the drafting of approximately 230,000 regulator-ready privilege log entries in just eight business days — reaching a peak of approximately 100,000 AI-drafted entries in a single day. This was not a fully automated output — it was a human-guided GenAI workflow with attorney validation and audit-ready controls built in at every stage.

The result: a faster, more consistent, and more defensible approach to meeting a significant production deadline. For any legal team that has stared down a privilege log of that scale, the implications are clear — and the regulator accepted the submission without follow-up inquiries on descriptive elements.

This is what operationalizing GenAI actually looks like. Not a demo. Not a pilot. A production matter, a real deadline, and a defensible result.

Three Areas Where Demand Is Growing in 2026

Following the eDiscovery AI acquisition, HaystackID is seeing increased demand in three specific areas where AI-enabled workflows are delivering the most immediate value for corporate legal teams:

DSAR Response

Data Subject Access Requests are volume problems as much as legal problems. As privacy regulations multiply across jurisdictions and consumer awareness increases, the volume of DSARs hitting corporate legal and privacy teams continues to rise. AI-enabled workflows can identify, classify, and surface responsive data faster, reducing the manual lift and compressing response timelines without sacrificing accuracy or defensibility.

Privilege Review and Privilege Log Drafting

Privilege review remains one of the most time-intensive and risk-laden steps in any litigation or regulatory matter. The privilege log example above demonstrates what’s possible when GenAI is applied thoughtfully — with human oversight at the center of the process. HaystackID’s approach is designed to produce entries that are consistent, complete, and ready for attorney sign-off, rather than requiring attorneys to generate them from scratch.

Regulatory Response

Regulatory matters are defined by compressed timelines, high stakes, and an adversarial audience scrutinizing every output. AI-enabled regulatory response workflows help teams move faster through document review, identify key facts and issues earlier, and produce cleaner, more consistent work product under pressure. When the regulator is waiting, speed and accuracy are not trade-offs — they’re both required.

Why Human-Guided AI Matters for Defensibility

Across all three of these areas, one principle remains constant in how HaystackID approaches GenAI deployment: the human has to stay in the loop.

This is not a philosophical position — it’s a practical one. Legal workflows produce outputs that get filed, produced, and scrutinized. Errors in a privilege log entry or a regulatory submission carry consequences. The governance controls and attorney validation steps built into HaystackID’s workflows exist precisely because the defensibility of the output is what clients are ultimately accountable for.

GenAI accelerates the work. Human judgment validates it. That combination is what separates a defensible workflow from a risk.

Flexible Delivery Aligned to Your Environment

HaystackID supports flexible delivery models across leading review environments, aligned to each client’s operational, privacy, and risk requirements. Whether a team is running workflows through Relativity, RelativityOne, or another environment, the goal is to meet corporate legal teams where they are — not to require them to adopt an entirely new stack in order to access AI-enabled capabilities.

What This Means for 2026 Planning

If your organization is evaluating GenAI providers for 2026 initiatives — or beginning to develop RFI and RFP criteria for managed legal services — HaystackID welcomes the conversation.

We can speak specifically to:

• Workflow design and governance controls for AI-enabled legal matters
• How the eDiscovery AI acquisition expands HaystackID’s capability set
• Specific use cases in DSAR, privilege review, and regulatory response
• Delivery models and platform alignment for your environment

The shift from evaluating GenAI to deploying it in real legal workflows is already underway. HaystackID is positioned to support that shift — with the track record to back it up. As you evaluate your 2026 initiatives, you can also submit a request for proposal directly to HaystackID to explore how these workflows align with your organization’s needs.
