Macpherson Kelley rolls out :Harvey: firmwide. by Harvey Team - Sep 2, 2026 Macpherson Kelley, a leading Australian commercial law firm with a 121-year history, is deploying Harvey firmwide across its lawyers and all eight practice groups. The firmwide rollout follows a year-long pilot and comprehensive evaluation of legal AI platforms. Macpherson Kelley selected Harvey for the strength of the platform and its approach to implementation and adoption, with Harvey's teams working closely alongside the firm's lawyers and leadership throughout the evaluation. During the pilot, Harvey's Customer Success and Legal Engineering teams worked onsite with Macpherson Kelley across Australia to identify high-impact use cases and develop workflows tailored to its practices. With the firmwide rollout, the teams will build on that foundation, expanding how Harvey supports the firm's lawyers across litigation, drafting, review, and other complex legal work while helping them deliver greater value for clients. "We spent a year evaluating Harvey with our lawyers and testing it against the alternatives before making the decision to go firmwide," said Grant Guenther, National Managing Principal at Macpherson Kelley. "What stood out was not only the strength of the platform, but the partnership behind it. Rolling out Harvey across the firm is an investment in our people and in how we continue to strengthen the service we deliver to our clients." "Macpherson Kelley approached this decision with tremendous thoughtfulness, taking the time to understand where Harvey could have the greatest impact across its practice," Ashleigh Whittaker, Australian Country Manager. "We're proud to support the firm as it brings Harvey to every lawyer and look forward to building on the strong relationship our teams have developed."
Introducing Horizon Scanning. Horizon Scanning helps legal teams monitor, assess, and take action on the changes that matter most. by Harvey Team - Sep 1, 2026 The pace of regulatory change isn't slowing down: 63% of legal departments say their monitoring and compliance workloads increased in 2026. Many existing monitoring tools don't even save teams time because alerts arrive through fragmented feeds, without prioritization, and siloed from where next steps need to happen. Changes can slip through, and it can be costly to miss a key update. Harvey is introducing Horizon Scanning in Harvey to help legal teams turn monitoring into actionable next steps. Teams can customize alerts, receive notifications for key regulatory and legislative updates, and immediately take action on the most impactful developments in one connected platform. Built with a cohort of design partners across law firms and in-house teams, Horizon Scanning helps legal teams quickly act on the changes that matter most. Create tailored scans relevant to you. Most monitoring tools draw from a fixed repository, which means coverage may be rigid or irrelevant to what your business prioritizes. With Horizon Scanning in Harvey, teams can simply describe what they need to track in plain language - a topic, a region, a named regulator. Harvey will automatically build a scan, drawing on more than 12,000 sources across 100+ jurisdictions alongside public sources the user describes. For example, an in-house team can shape the scope of a scan to data protection developments in the jurisdictions where the company actually holds data, or create a separate scan for each subsidiary. Quickly identify which changes matter most. Every scan feeds a single dashboard that shows what moved, with the most consequential developments surfaced first. Determining what changed is just the first step - the critical work is understanding who it affects, what they need to do, and by when. Each update arrives with a relevance assessment, so that it is easy to gauge urgency before digging into the details. Teams can also receive email digests of daily changes, helping them access insights directly in their inbox. Let's say there's a new anti-money laundering rule that impacts a financial services legal team. They can find out about the change the same day it's published via an email alert. Then, Harvey can help them quickly determine which entities are impacted, what has to change operationally, and how long they have to prepare. Move from update to next step. Since Horizon Scanning is part of Harvey's agentic platform, alerts connect to downstream work in one single system. Ask a question about a development in plain language and get an answer grounded in the source. Teams can turn scans into a memo revision, a recommended policy update, or an interactive timeline of upcoming obligations without leaving the dashboard. For a firm's privacy practice, that can mean tracking data protection regulators across member states, updating guidance by directly pulling the right documents from their DMS into queries, and drafting a client alert the same day new guidance lands. For an in-house compliance team, it can mean Harvey directly flagging which internal policies are affected by a tariff change and suggesting revisions, helping them draft new guidelines and flag any operational concerns faster. Scans can be shared across a team, so practice groups and business stakeholders work from the same view. Harvey is building Horizon Scanning as a foundation for proactive legal work in Harvey, where monitoring, analysis, and the work that follows all live in one place. Horizon Scanning is currently available in Early Access for Harvey customers, with general availability to follow. If you're interested in learning more about Harvey, get in touch with its team.

How citation verification actually works (and Why "trust me" Isn't enough). In the early days of generative AI, the defining legal tech disaster was the attorney who submitted fake, AI-hallucinated case law to a federal judge. It was a wake-up call that raw Large Language Models (LLMs) like ChatGPT or Claude are prediction engines, not legal databases. Yet, years later, many attorneys are still relying on single-model wrapper SaaS products that ask them to simply "trust the output." For solo practitioners in California, this is a dangerous gamble. Under California Rule of Professional Conduct (CRPC) 3.3 (Candor Toward the Tribunal) and Rule 1.1 (Competence), an attorney is strictly responsible for the accuracy of every citation in their filings. Sanctions under California Code of Civil Procedure (CCP) § 128.7 for frivolous or baseless claims apply whether you hallucinated the case yourself or outsourced the hallucination to an AI. At VivaceWorks, VivaceWorks LLC believe that AI should never ask for your blind trust. Instead, it must show its work through rigorous, deterministic citation verification. Executive Summary * The Illusion of Certainty: Raw LLMs prioritize persuasive language over factual accuracy, making their hallucinations incredibly convincing. * Why Basic RAG Fails: Simple Retrieval-Augmented Generation (RAG) can pull irrelevant case law if the search parameters are poorly constrained. * Deterministic Verification: True citation verification requires secondary AI agents (a "Red Team") explicitly designed to cross-reference citations against authoritative databases like CourtListener and verify exact pin cites. * Risk Mitigation for Solos: Using multi-agent verification workflows satisfies the duty of supervision (CRPC 5.3) and prevents career-ending filing errors. The anatomy of a legal AI hallucination. Why do AI models hallucinate cases? Because they are designed to predict the most statistically probable next word, not to fetch records from a database. When you ask a generic AI for a case supporting a niche employment law theory in California, it might recognize that a citation to Smith v. Superior Court from the Second Appellate District sounds highly plausible. It will generate the citation, complete with a realistic-looking volume and page number (e.g., 234 Cal.App.4th 101), because that is structurally correct - even if the case itself doesn't exist. Competitors like Harvey AI and CoCounsel attempt to solve this by tightly coupling their models with massive proprietary databases (like LexisNexis or Westlaw). But for solo practitioners, these enterprise-tier solutions often come with crippling seat minimums and six-figure annual commitments. How Deterministic Verification solves the problem. If enterprise walled gardens aren't the answer, what is? The solution lies in multi-agent deterministic verification. Here is how AI Paralegal v2 breaks down the verification process step-by-step: 1. The Generation phase. First, a primary drafting model (such as Claude Opus 5) generates the initial argument and proposes supporting case law based on the facts provided. At this stage, the citations are treated as hypotheses, not facts. 2. The red Team extraction. A secondary, specialized AI agent scans the draft specifically to identify every legal assertion and citation. It extracts the case names, reporter volumes, and pin cites into a structured format, isolating them from the persuasive text. 3. Database cross-referencing. The system then queries a deterministic, non-AI database - such as the open-access CourtListener API or a firm's own indexed precedent library. It checks for: * Does the case exist? * Is the citation format correct? * Is the quoted text actually present at the specified pin cite? 4. The human-in-the-loop override. Finally, the verified draft is presented to the attorney in a unified control center. Verified citations are highlighted in green with links to the source text. Any citation that failed verification is flagged in red, requiring the attorney to either replace it or manually verify it. | Approach | Mechanism | Solo Practitioner Reality | | Generic Wrappers (Clio AI, ChatGPT) | Single LLM prompting; basic RAG. High risk of hallucination; requires manual verification of every cite. | | Enterprise Walled Gardens (Harvey, Westlaw) | Proprietary DB integration. Cost-prohibitive for solos; inflexible contracts. | | AI Paralegal v2 | Multi-agent API routing & CourtListener cross-referencing. Zero hallucinations; transparent verification; affordable solo pricing. | Meeting the standard of care in California. The State Bar of California has made its position clear: using AI does not alter your ethical obligations. CRPC Rule 5.3 requires attorneys to supervise non-lawyer assistance - and the Bar considers AI tools to fall under this umbrella. You cannot delegate your professional judgment. By using a platform that enforces deterministic citation verification, you are building a documented workflow that demonstrates compliance with your duty of competence. You aren't just saving time; you are systematically mitigating malpractice risk. "Trust is not a legal strategy. When your license is on the line, your software must provide proof, not just promises." - Steve Luk, Founder & Lead Architect Ready to see this in action? AI Paralegal is now generally available for California solo practitioners with custom pricing based on your specific needs and workflow.
Jackson Lewis deploys :Harvey: firmwide. by Harvey Team - Aug 24, 2026 Nationwide employment law firm Jackson Lewis P.C. is expanding its investment in artificial Intelligence by deploying Harvey firmwide to more than 1,100 attorneys across more than 60 offices. Following a comprehensive evaluation of AI platforms, Jackson Lewis selected Harvey for the strength, versatility and legal-focused capabilities of its platform, as well as the opportunity to partner with Harvey's Legal Engineering and implementation teams. Together, Jackson Lewis and Harvey are identifying and implementing high-impact applications across the firm designed to enhance attorney efficiency, streamline matter management and support the delivery of complex, strategic work that creates the greatest value to clients. Harvey's Legal Engineering team will collaborate directly with Jackson Lewis attorneys and business professionals to develop applications tailored to the complexities of labor and employment law, while deepening the relationship between Jackson Lewis and Harvey to accelerate innovation and advance the firm's use of generative AI. "Jackson Lewis has built its reputation by staying focused on what our clients need and continually evolving how we serve them," said Firm Chair Kevin Lauri. "As a leader in labor and employment law, we see AI as an opportunity to build on that strength, and Harvey stood out as the right partner to help us do it. The technology is impressive, but just as important to us is having a team that will work alongside our lawyers to turn that potential into real value for our clients." "Jackson Lewis brought both a high bar and a clear vision to this process," said Winston Weinberg, CEO of Harvey. "As a leader in labor and employment law, the firm was looking for technology that could support the breadth and complexity of its work at scale, along with a team that could help translate the potential of AI into practical applications for its attorneys and clients. We're proud to have been selected as the partner to help advance that vision."
:Harvey: partners with PacerPro to bring real-time docket intelligence to litigators. by Harvey Team - Aug 21, 2026 Harvey and PacerPro today announced a partnership that brings the federal and state court records captured and structured by PacerPro into Harvey's legal AI platform, giving litigators a more direct path from case activity to action. PacerPro captures state and federal court filings and their underlying documents as they post, connects each filing to its case and docket history, and organizes that activity into a continuously updated record of the firm's litigation, matter by matter. This is the information litigation teams work from every day and it has typically lived outside the tools lawyers use to research, draft, and analyze. The partnership between Harvey and PacerPro is designed to support the ways litigation teams already use docket data on a daily basis, including state and federal docket monitoring, litigation workflow automation, and real-time filing alerts, with PacerPro serving as the court data and workflow infrastructure enabling the integration. This reflects Harvey and PacerPro's shared goal of giving litigators a single, trusted place to track case activity and act on it. That record is both current and cumulative: the filings arriving in the firm's matters now, and the briefing, rulings, and outcomes from the matters that came before. "We started PacerPro because the real value of the court record isn't a docket entry telling you that something happened. It's what was filed," said Gavin McGrane, CIO and Co-Founder at PacerPro. "That's where law meets fact - where lawyers make arguments and courts decide them. We've spent more than a decade capturing that work for firms and connecting it to the matters it belongs to. With Harvey, a filing that arrives today can be understood in the context of the case behind it and the firm's experience before it. We've been waiting for this." "Our partnership with PacerPro brings their deep expertise in court data and litigation workflows into Harvey," said Megan McMillin, Legal Innovation Partner at Harvey. "I spent years watching litigators move filings between systems before they could start their real substantive work. Now current case data flows directly into lawyers' daily workflows in Harvey, so they can move immediately to analysis and drafting." PacerPro has spent over a decade building infrastructure for federal and state court data and currently captures activity across all federal district, bankruptcy, and appellate courts and more than 30 state courts. Its record includes more than 20 million court filings since 2015, with new activity generally reaching PacerPro within one to two minutes of publication. This partnership connects that infrastructure to Harvey's growing ecosystem of data connectors, which deliver the documents, data, and institutional knowledge legal professionals rely on directly into their workflows. The court record is a natural extension of that effort, giving litigation teams court activity they can understand and act on the moment it's available. Harvey and PacerPro will demonstrate the integration live at ILTACON 2026 in Nashville on Tuesday, August 25, at the Harvey booth.
