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:
- Integration: Access CoCounsel directly within the Thomson Reuters ecosystem (e.g., Westlaw Precision, Checkpoint) or integrated platforms like Microsoft 365.
- 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."
- 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.
- 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.
