Description
CoCounsel, developed by Thomson Reuters, is an industry-leading AI platform engineered for professionals who cannot afford to be wrong. It goes beyond mere speed enhancement, aiming to improve the quality and defensibility of professional work. CoCounsel is built on the principle of Fiduciary-Grade AI™, a standard for AI in high-stakes professions that emphasizes duties of care and regulatory oversight.
The platform is designed to accelerate legal, tax, audit, compliance, and drafting tasks with purpose-built AI. Its core strength lies in being grounded in authority, transparency, and trust. Every experience is crafted to help professionals produce work that can be examined, explained, and defended, ensuring it stands up to scrutiny. CoCounsel achieves this by being grounded in authoritative, expert-validated content and proprietary sources.
Integration is a key aspect of CoCounsel's design, connecting seamlessly with tools professionals already use, including Westlaw, Practical Law, Checkpoint, Microsoft 365, and various document management systems. This frictionless integration ensures that users can leverage AI without disrupting their existing workflows. Furthermore, CoCounsel is protected by enterprise-grade privacy and security safeguards, ensuring that sensitive professional work remains confidential and protected.
CoCounsel differentiates itself from generic AI tools by providing answers grounded in authoritative content and offering transparency and verifiability. When accuracy is paramount, CoCounsel surfaces sources and reasoning, allowing users to confidently verify and defend their work. This domain expertise, combined with rigorous testing and refinement by subject-matter experts, ensures the AI's accuracy and nuance for professional workflows.
Trusted by over 1 million users, CoCounsel is not intended to replace professional judgment but to support it. Professionals remain ultimately responsible for their advice, decisions, and signed-off work. The platform's commitment to enterprise-grade protection means customer data is secured with rigorous privacy and security controls, including TLS 1.2 encryption in transit and AES-256 encryption at rest. All GenAI LLM requests are processed under the identity of Thomson Reuters, never identifying the specific customer, and interactions with AI providers use zero-retention API calls.
