Hutchinson and Bloodgood | Professional Services | 195 | $27M | United States | Thomson Reuters Elite | Thomson Reuters CoCounsel | Generative AI Platforms | 2025 | n/a |
In 2025, Hutchinson and Bloodgood implemented Thomson Reuters CoCounsel alongside Thomson Reuters Cloud Audit Suite and Audit Intelligence Analyze, marking a firm adoption of Generative AI Platforms to support its audit practice. The announcement ties the deployment explicitly to AI powered workflow improvements for audit teams and a cloud first delivery model that centralizes content and methodology.
Thomson Reuters CoCounsel is positioned as the generative AI layer to streamline audit workflows, while Cloud Audit Suite delivers the firm methodology and industry content required by auditors, and Audit Intelligence Analyze provides AI assisted analysis capabilities. Configuration focused on cloud hosted content updates and AI assisted task support consistent with Generative AI Platforms functional patterns, reducing local workstation maintenance.
The technical architecture emphasized a single cloud based system, which removes the need to install updates on individual workstations and guarantees all users access to the latest content, supporting seamless integration into H and B audit processes. Operational scope centers on the firm audit function, with the solution intended to be the authoritative source of methodology and industry content for audit teams across the practice.
Governance and rollout references in the announcement highlight a simplified transition to cloud and consolidated content management, enabling centralized content versioning and consistent methodology application across engagements. The firm cited outcomes that include streamlined audit workflow, simplified work processes, and improved operational efficiency as direct benefits of the Thomson Reuters CoCounsel and Cloud Audit Suite deployment.

Lagerlof | Professional Services | 120 | $15M | United States | Thomson Reuters Elite | Thomson Reuters CoCounsel | Generative AI Platforms | 2024 | n/a |
In 2024, Lagerlof implemented Thomson Reuters CoCounsel by embedding CoCounsel Drafting capabilities into its legal drafting workflows, adopting the application from the Generative AI Platforms category. The deployment centers on Microsoft Word integration, allowing attorneys to run drafting and review tasks without leaving the document editor, and positions Thomson Reuters CoCounsel as the firm’s generative AI assistant for substantive legal drafting and contract review.
The implementation configures CoCounsel Drafting modules for end to end drafting workflows, including finding optimal starting points from Practical Law and the firm’s contract repository, searching curated clause libraries, drafting and modifying clause language using natural language prompts, and automating deviation analysis against Practical Law contract playbooks. The configuration also uses built in error correction and automated redlining to streamline clause revision and reduce manual mark up during contract negotiation.
Integrations in the deployment explicitly include Microsoft Word, Practical Law content, Contract Express templates, and the firm’s internal contract repositories and SEC exhibits as searchable sources, enabling clause reuse and playbook comparisons within a single authoring surface. Operational coverage targets the firm’s attorneys across practice teams, with adoption noted among attorneys at various career stages, and the vendor roadmap indicates additional litigation drafting capabilities and expanded regional availability later in the year.
Governance and process changes focus on embedding CoCounsel Drafting into existing document authoring and review checkpoints, minimizing training needs due to seamless Word integration. Lagerlof leadership reported that attorneys estimate time savings of at least one to two hours per project, and cited examples where average turnaround moved from three to four business days down to one to two business days when using the tool, reflecting the firm level expectations for faster drafting cycles and delegated substantive task handling by Thomson Reuters CoCounsel.

Magone & Company | Professional Services | 10 | $1M | United States | Thomson Reuters Elite | Thomson Reuters CoCounsel | Generative AI Platforms | 2024 | n/a |
In 2024, Magone and Company implemented Thomson Reuters CoCounsel as part of Checkpoint Edge with CoCounsel under the Generative AI Platforms category to support firm tax research and client correspondence workflows. Thomson Reuters CoCounsel was provisioned to deliver an AI-assisted Research skill for Federal Tax, with the platform already extended to include State Tax coverage and AI conversational capabilities in the United States since its July 2024 general availability.
The implementation focused on functional capabilities rather than broad infrastructure changes, using CoCounsel summaries and citations to standardize research outputs and to streamline drafting of client communications. Features deployed include the AI-assisted Research skill, conversational query handling, copy print and export controls, and curated topic pages managed by Thomson Reuters editorial teams, which together supported tax research, answer validation, and document generation workflows.
Operational rollout targeted the firm s tax professionals and leveraged a lightweight adoption path, with staff brought online after a simple email introduction and rapid uptake by younger professionals already familiar with consumer AI tools. The deployment scope was practice level, embedding CoCounsel into daily research and correspondence processes rather than enterprise IT rearchitecting, and it emphasized user-facing configuration and training to drive consistent use of summaries and citation outputs.
Governance centered on workflow change and quality control for client deliverables, with CoCounsel used as an assistive research layer to reduce time spent on research and to improve the consistency and quality of client communications, outcomes explicitly reported by the firm. The narrative for Magone and Company positions Thomson Reuters CoCounsel within Generative AI Platforms as an integrated research and drafting capability for small professional services firms focused on tax work.

Sullivan Papain Block McManus Coffinas and Cannavo | Professional Services | 100 | $35M | United States | Thomson Reuters Elite | Thomson Reuters CoCounsel | Generative AI Platforms | 2025 | n/a |
In 2025, Sullivan Papain Block McManus Coffinas and Cannavo began using Thomson Reuters CoCounsel, a Generative AI Platforms application, to support its New York medical malpractice and personal injury practice. The deployment was driven by partner-level adoption, with Aquila serving as an early tester and primary user, integrating CoCounsel into day to day casework across the firm’s attorneys.
Thomson Reuters CoCounsel is used for high-volume document review, targeted search, timeline creation, litigation summarization, and structured extraction of billing and treatment codes. The application has been employed to process multi-thousand page record sets, surface specific factual history, and break down complex Medicare lien data while performing arithmetic on extracted items, demonstrating functionality aligned with enterprise document ingestion and natural language summarization capabilities.
Operationally CoCounsel sits inside the Thomson Reuters ecosystem and integrates with Westlaw, enabling attorneys to move between legal research and generative AI analysis without fragmenting workflow. Users keep CoCounsel open on desktop workstations to submit ad hoc queries while multitasking, and the tool is applied across active case files including discovery review, motions analysis, and lien assessment.
Rollout and governance began informally through an initial tester group, with peer led adoption and usage guidance from early users like Aquila who encouraged colleagues to experiment. The Westlaw integration and the vendor ecosystem were cited as trust and security factors that supported firmwide acceptance, and adoption emphasis focused on embedding CoCounsel into existing legal review and motion preparation workflows.
Observed outcomes reported by the firm include substantive time savings and improved case outcomes in specific matters. In one instance CoCounsel located relevant history in a 6,000 page record set in approximately seven minutes after a colleague had searched for two hours without success, materially supporting settlement. In another matter the tool searched 16,000 pages of nursing home records for evidence about bed rails, and it parsed Medicare lien documents to identify relevant codes and compute totals, supporting more efficient client counseling and case valuation.

Systemiq | Professional Services | 339 | $47M | United Kingdom | Thomson Reuters Elite | Thomson Reuters CoCounsel | Generative AI Platforms | 2024 | n/a |
In 2024 Systemiq deployed Thomson Reuters CoCounsel, a Generative AI Platforms application, to augment its legal drafting and contract review workflows. The rollout centered on Thomson Reuters CoCounsel Drafting embedded directly into Microsoft Word, enabling end to end drafting without leaving the authoring environment and minimizing user training overhead.
The implementation used CoCounsel Drafting capabilities to establish a structured drafting stack, including identification of best starting points from internal contract repositories, use of Contract Express templates and Practical Law content, clause search across curated clause libraries and SEC exhibits, natural language driven clause drafting and modification, and automated deviation analysis and redlining against Practical Law contract playbooks. These functional modules were configured to support clause refinement, error correction and iterative review within the Word document lifecycle.
Integrations implemented were explicit and content centric, linking Thomson Reuters CoCounsel to Practical Law, Contract Express templates and the firms contract repository to surface organization specific language and Practical Law standards. Operational coverage targeted Systemiqs legal function, with Systemiq legal counsel using the solution for drafting, clause discovery and rapid review processes in the United Kingdom.
Governance and workflow restructuring prioritized playbook driven review and automated deviation analysis to standardize clause acceptance paths and reduce manual redline overhead. Systemiq reported an explicit reduction in average turnaround from three to four business days down to one to two business days when using the tool, and external beta feedback cited attorneys saving one to two hours per project, highlighting reduced cycle time and faster internal review loops while keeping work inside Thomson Reuters CoCounsel and Microsoft Word.
