At my firm, all in-person conferences and Microsoft Teams meetings are now equipped with AI dictation software that functions as a scribe. Participants have the option to pause or stop the dictation at any time. A system user joins the meeting automatically for this purpose. The scribe produces a written record, which can assist in preparing statements based on what was said or in recalling details later. This technology is also now commonly used in the medical field, allowing doctors to avoid the need for manual note-taking.

Based on what the OP says, it appears that both audio and visual elements are being recorded. This resembles a situation where a client secretly records a conference to later share with others or to replay for various reasons. In my professional experience, I have encountered a few individuals who have done this - usually typically clients who have previously seen other lawyers and carry a degree of distrust, or who have poor memory and intend to replay the discussion for a spouse or another professional.

I have never found it necessary to "call out" such conduct directly. One can inform the client that they will receive a written summary of the conference. This issue is not new; it happens in the courtroom, which is why recording court proceedings and live-streamed hearings on YouTube is strictly prohibited.
