People get busy. A useful consumer AI account is already open. A client email, draft clause, or fact pattern gets pasted in because the deadline is closer than the policy manual.
Cloud AI is not automatically the problem. Unmanaged accounts, uncertain settings, broad history, changing features, and invisible staff behavior are the problem. Some assistants can now search prior conversations for context. That is convenient, but it also makes retention and access decisions more important.
The practical answer is one approved front door that makes the safer route the easiest route.
