Is CoCounsel a 'robot lawyer'?

No. CoCounsel is a legal assistant designed to enhance efficiency and handle mundane tasks. It does not replace the independent judgment of an attorney, who must always oversee and verify its outputs.

How does CoCounsel ensure data security?

CoCounsel uses enterprise-grade security, including SOC 2 compliance. Your data is kept private, is not used to train global models, and is stored in a secure environment hosted by Thomson Reuters.

Can I use CoCounsel if I don't have Westlaw?

Yes, CoCounsel Core can be used with your own uploaded documents. However, its legal research capabilities are significantly enhanced when integrated with Westlaw or Practical Law.

What is 'Agentic AI' in CoCounsel?

Agentic AI refers to the platform's ability to act like a senior associate by planning and executing complex, multi-step workflows autonomously rather than just responding to single prompts.

Does it support languages other than English?

While it is used by professionals in 107 countries, its core legal research and authoritative content integrations are currently optimized for English-language legal systems.
