Trained for the law

GPT-4 is powerful, but legal professionals need more. Our attorneys and AI specialists spent months developing and repeatedly testing an OpenAI-powered solution tailored to lawyers’ needs and reliable and secure enough to meet the highest bar.

Private and secure

CoCounsel uses dedicated servers to access GPT-4, meaning your data isn’t sent to “train” the model as part of publicly accessible knowledge. Your and your clients’ information stays private and is secured by bank-grade AES-256 encryption.
“The Search a Database skill is the Holy Grail.”

Partner, Nidel & Nace, PLLC

Supercharge transactional work

CoCounsel handles time-consuming tasks with ease, such as extracting 
all relevant info from entire contract databases and checking contract 
policy compliance.

Offload the heavy lifting in litigation

CoCounsel gives litigators a competitive edge by helping with everything from research and memo drafting to document review and deposition prep.
Instead of taking hours to complete tasks, CoCounsel works in minutes. Our attorneys have more time to focus on the more human aspects of law, like developing client relationships.

Grounded in reliable data sources

CoCounsel output is only drawn from reliable sources of data relevant to its specific use and returns results that cite to verifiable sources. CoCounsel harnesses the power of LLMs but limits the source of knowledge to your own or your clients’ databases. And by always citing to sources, CoCounsel makes it easy to work responsibly, that is to “trust, but verify.”

Tested and authenticated

Our dedicated team of domain experts ran more than 600,000 tests on CoCounsel in its first year in market, with a daily battery of tests developed to simulate real-life use cases. Our Trust Team—experienced AI engineers and professional attorneys—filter, rank, and score output of thousands of sophisticated questions to ensure consistency and accuracy. 

Private and secure

CoCounsel accesses GPT-4 through dedicated, private servers, and through an “eyes off” API. No OpenAI employees can see customer queries or documents. Your and your clients’ information is encrypted in transit and at rest, and subject to Thomson Reuters' rigorous security policies and practices.
