Parent comment was asking about attorney-client privilege which means there's an attorney in the communication loop. If the person using a tool is an attorney, then that communication should be protected whether it's by pen or keyboard. But this is an active area of legislation and jurisprudence in relation to AI. I expect some important cases will happen
Just because they have a lawyer does not mean things like their browser history and every other example in the comment I replied to would not be permitted as evidence...
Except for something like specifically looking up a lawyer

But the tool is not your attorney, so it can't be the originator of attorney-client privilege. The situation is no different than if you get informal legal advice from a friend: even if that friend is an attorney, the communication is unprivileged unless it's part of a formal representation.
