There is a category of sentence that should never exist twice. The theory of a case before it is filed. The weakness a client admitted behind a closed door. The number below which the board will settle. Professional privilege was invented to protect exactly these sentences, and for five hundred years the technology of privilege was simple: a closed door, a locked drawer, a trusted clerk.
Then, in the space of three years, the professions quietly acquired a new clerk. Lawyers now draft with artificial intelligence. Surveys of the profession find a majority using such tools, and the same surveys find the same anxiety at the top of every list: where does the text go? The honest answer is that a prompt is a disclosure. It travels to infrastructure owned by a vendor, governed by terms the user has never read, retained under policies that can change with an email, in jurisdictions selected for tax efficiency rather than privilege law. The cloud does not sign a confidentiality undertaking. It publishes one, and reserves the right to amend it.
Regulators have begun saying this aloud. California’s bar has proposed amending its confidentiality rule so that exposing client information to an AI system that may retain or reuse it counts as revealing it. Courts in more than one country have sanctioned lawyers whose tools invented authorities; a public tracker now counts the proceedings in four figures. The direction of travel is unmistakable: the professional will be answerable not only for what the machine says, but for where the question went.
There are two responses. One is abstinence, which is untenable; the advantage conferred by these tools is too large, and clients will not pay for hand-loomed work at machine prices. The other is the old answer in new hardware: bring the clerk inside. Machines now exist that hold a modern intelligence entirely within a room, on hardware the professional owns, with nothing leaving the premises, no account, no telemetry, no jurisdiction but one’s own. The technology of privilege is becoming, once again, a locked door.
The professionals who understand this first will not advertise it. Discretion, as ever, is the point.
