**Frequently asked questions**
------------------------------
What is the difference between CoCounsel, CoCounsel branded products, and existing Thomson Reuters products enhanced by CoCounsel? down arrow
CoCounsel is the GenAI assistant for professionals, available wherever you work within the Thomson Reuters ecosystem or integrated platforms such as Microsoft 365.
CoCounsel branded products offer unique skills, such as Search a Database and Review Documents within CoCounsel Core. CoCounsel can also focus on assisting in a specific area of work like faster drafting within CoCounsel Drafting.
Existing TR products enhanced by CoCounsel are standalone products that integrate CoCounsel to facilitate specific tasks such as Westlaw Precision with CoCounsel’s AI-Assisted Research, helping users save time and maximize the value of their access to trusted Thomson Reuters content.
Does Thomson Reuters or third parties retain user content or prompts to train their GenAI-based products or underlying large-language models (LLM)? down arrow
No. Your user content and prompts are not used to train or improve CoCounsel and associated products or LLMs, used in Thomson Reuters or third-party output, or stored by OpenAI or Google.
Thomson Reuters GenAI third-party partners, such as OpenAI and Google, are contractually prohibited from using any customer data to train their models. Additionally, where applicable, Thomson Reuters has established systemic controls to turn off third parties' abuse-monitoring solutions to ensure there is no human access to Thomson Reuters customers' data or inclusion of that data in third-party models.
How long does Thomson Reuters retain user content and prompts? down arrowRetention of user content and prompts is customized to fit customer needs and set up at the organization account level with the support of a Thomson Reuters client manager. We then delete user content and user prompts in accordance with the customer's retention policy. Users can delete their content and prompts in the product at any time. How does Thomson Reuters protect user privacy and data? down arrow
All GenAI LLM requests originating from Thomson Reuters are processed under the identity "Thomson Reuters," never identifying the Thomson Reuters customer who made the request. We secure all data in transit via TLS 1.2, and symmetric encryption (AES-256) protects data at rest. All interactions with GenAI LLM providers use zero-retention API calls.
Where are user content and user prompts stored when retained? down arrow
Systematic procedures and hosting are in the U.S. We process all interactions with OpenAI GPT and Google Gemini in the U.S. We host backup data in separate availability time zones in the U.S.\*
\*Region-based hosting is available in the UK, Australia, and Canada.
What guardrails are in place to prevent bias in Thomson Reuters content? down arrow
We have developed and implemented prompting "guardrails," ensuring our GenAI-based products will only produce responses from content drawn from a clearly defined and limited set of verified information, such as our own content databases. This practice restricts the large language model's ability to produce potentially objectionable content broadly sourced from the internet.
