CoCounsel Overview

CoCounsel is the industry-leading generative AI assistant developed by Thomson Reuters, built upon the pioneering technology of Casetext. It is designed to serve as a trusted partner for professionals in the legal, tax, audit, and accounting fields. By delegating substantive, time-consuming work to this powerful AI, professionals can shift their focus to more complex, high-value strategic tasks that better serve their clients and business objectives. CoCounsel is engineered by over 1,000 GenAI and machine learning experts and is grounded in the industry's most trusted and reliable content, ensuring accuracy and limiting algorithmic bias.

The platform offers a fluid connection to the solutions professionals use daily, understanding context and nuance across different products and workflows. This deep integration allows users to derive in-depth insights faster than ever before. Security and privacy are paramount, with CoCounsel guaranteeing that a user's sensitive data is secure, private, and never used to train any AI models, including those from third-party partners like OpenAI and Google.

How to use CoCounsel

Using CoCounsel is designed to be intuitive, functioning like a highly capable assistant. Professionals interact with it through natural language prompts within their existing workflows. Here’s a typical process:

  1. Integration: Access CoCounsel directly within the Thomson Reuters ecosystem (e.g., Westlaw Precision, Checkpoint) or integrated platforms like Microsoft 365.
  2. Task Delegation: Instead of manual research or review, you can ask CoCounsel to perform specific tasks. For example, you can ask, "What are the key risks in this contract for my client?" or "Summarize recent case law regarding intellectual property disputes in the tech sector."
  3. AI-Powered Actions: CoCounsel utilizes its specialized skills, such as AI-Assisted Research, Document Review, or Drafting, to process the request. It searches through verified databases, analyzes provided documents, or generates text based on your instructions.
  4. Receive and Refine: The AI provides a comprehensive, well-supported response, often with citations to the source material. Professionals can then use this output as a strong starting point, applying their own judgment and expertise to refine the final work product. This collaborative process saves significant time on foundational tasks.

Core Features of CoCounsel

  • AI-Assisted Research: Ask complex questions in plain English and receive synthesized answers with direct links to authoritative sources from Westlaw, Practical Law, and other trusted databases.
  • Document Review and Analysis: Rapidly analyze thousands of documents to extract key information, identify critical clauses, find inconsistencies, or check for compliance.
  • Drafting Assistance: Generate drafts of legal memoranda, client communications, contract clauses, and other documents, significantly speeding up the writing process.
  • Deposition Preparation: Summarize lengthy deposition transcripts to pinpoint key testimony and help attorneys prepare for questioning.
  • Contract Analysis: Automate the review of contracts to identify risks, obligations, and non-standard terms, comparing them against established standards.
  • Seamless Integration: Natively integrated with industry-leading platforms including Westlaw, Practical Law, Checkpoint, Microsoft 365, and various document management systems.

Use Cases for CoCounsel

CoCounsel is versatile and provides value across several professional domains:

  • Law Firms: Attorneys can use CoCounsel to drastically reduce the time spent on legal research, e-discovery document review, and preparing case summaries. A partner at a mid-size firm noted it saves an exponential amount of time by centralizing the search for answers.
  • Corporate Legal Departments: In-house counsel can leverage the tool for rapid contract review, ensuring compliance with internal policies and external regulations, and managing internal investigations more efficiently.
  • Tax and Accounting Professionals: Tax partners can use CoCounsel to research complex tax codes, understand new regulations, and automate the initial 80% of research-intensive tasks, allowing them to focus on strategic advice and client reasoning.

Advantages of CoCounsel

  • Trustworthy and Reliable: Responses are grounded in Thomson Reuters' authoritative and proprietary content, minimizing the risk of hallucinations and providing verifiable information.
  • Unmatched Security and Privacy: Employs industry-standard encryption and zero-retention API calls. Customer data is never used for training AI models, ensuring complete client confidentiality.
  • Enhanced Efficiency: Automates routine and research-heavy tasks, freeing up professionals to concentrate on strategic thinking, client relationships, and high-level analysis.
  • Expert-Driven Technology: Developed and maintained by a large team of AI experts in collaboration with subject-matter specialists in law and finance.
  • Workflow Integration: Designed to work within the tools professionals already use, ensuring a smooth adoption curve and maximizing productivity without disrupting established processes.
