As employees lean on tools like ChatGPT and Claude for research and writing at work, they need to understand that every prompt creates a permanent, reviewable record accessible by the LLM providers and, in some cases, by law enforcement.

• Roughly one‑third of employee ChatGPT inputs include confidential information such as customer details, internal documents, or proprietary code, raising serious data‑exposure and compliance risks for employers.

• Conversations are routinely logged on LLM servers, may be retained for months or years, can be reviewed by humans, and remain accessible to the provider when responding to lawful requests even when users turn off “chat history” or opt out of training.

• Organizations must instruct employees to treat LLM chats like email: create clear policies for what may be shared, prefer enterprise or self‑hosted LLMs, and remind staff that anything they type into a public AI tool can be discoverable in lawsuits and audits just like any other written communication.
