CoCounsel

Tool for legal document review, research memos, deposition preparation, and contract analysis. Thomson Reuters CoCounsel is AI technology built by industry experts, backed by authoritative content and equipped with best-in-class security. CoCounsel is an AI-powered assistant that handles research, document analysis, and drafting for professionals, mainly lawyers and tax experts. It uses agentic and generative AI to automate tasks like legal memos or tax reviews, grounded in trusted sources like Westlaw and Checkpoint. It’s ideal for firms wanting to cut down on routine work while keeping high accuracy, with over 20,000 law firms already using it, including most Am Law 100 ones. It connects seamlessly with Westlaw for research, Practical Law for drafting playbooks, Checkpoint for tax insights, and Microsoft 365 apps like Word and Teams for direct edits or queries. This lets you pull context from your daily tools without switching apps, saving time on things like contract reviews in Word. Users report it feels like a natural extension of their workflow. Key skills include Deep Research for multi-step legal plans, document comparison for spotting differences in contracts, deposition prep by analyzing transcripts, and drafting with built-in citations. It excels at summarizing long docs or building chronologies, often finishing in minutes what takes hours manually. Recent betas add agentic workflows for end-to-end tasks like complaint drafting. CoCounsel Tax automates research memos from IRS codes and Checkpoint, reviews returns for issues, drafts letters like penalty abatements, and spots savings opportunities like cost-segregation studies. A tax partner from a top U.S. firm said it handles 80% of a one-hour process, leaving room for judgment. It integrates with Excel and DMS for smooth tax planning. CoCounsel Core starts at $225 per user per month, with volume discounts for firms; full access via Westlaw Precision bundles it cheaper for subscribers. Tax versions vary, but expect $400+ monthly for advanced features, billed annually. Trials last 2-3 months, though some users note the "free" part ties into longer contracts. Smaller firms get Essentials plans scaled to growth. It uses TLS 1.2 for transit, AES-256 encryption at rest, and zero-retention API calls so prompts aren’t stored or used for training. Data stays in the U.S. (with options in UK, Australia, Canada), and partners like OpenAI can’t access it. Retention follows your policy, and you can delete anytime. Guardrails limit outputs to verified content to cut bias.
