What is CoCounsel AI?

CoCounsel is an AI legal assistant developed by Thomson Reuters that helps lawyers with case research and document analysis. It uses machine learning to review legal documents, identify relevant case law, and extract key information from contracts and briefs. The tool is designed to save time on repetitive research tasks and help legal professionals work more efficiently. It's built on established legal databases and integrates with existing legal workflows, making it a practical addition to a lawyer's toolkit rather than a replacement for human judgment.
