The tool is inside the regulated perimeter
The governance question that comes before every other one is whether the tool sits inside or outside the firm's supervised environment, and most firms discover the answer late.
An advisory firm operates a supervisory system: communications are captured, records are retained for prescribed periods, and someone is responsible for reviewing them. That system was designed around email, telephone and approved messaging platforms.
A generative AI tool used for client work creates communications and work product that may fall within the same requirements. If an advisor works through a client's position in a chat window, that exchange concerns advice, involves client information, and lives somewhere the firm's retention system does not reach.
This is structurally the same problem as off-channel communications, which regulators have pursued firms over at significant scale. The difference is that off-channel messaging was obviously a channel. A chat window feels like a tool, more like a calculator than like a conversation, and the categorisation error follows from that feeling.
FINRA's Regulatory Notice 24-09 makes the position explicit: the supervision obligation under Rule 3110 applies whether the firm develops the tool itself or uses a third party's, including AI features embedded in existing products.
The practical consequence. The first decision is procurement, not usage. Which tools are approved, do they retain in a way the firm can access, and is the output reviewable. An advisor using a personal account for client work has created a supervision gap regardless of how good the output is.
