Unfortunately, there is no Church-sponsored solution, and from what I've seen here in the Tech Forum, there's a wide variety of implementations. A lot depending on the tech-savviness of the local members, and also challenging to keep up with the rapid improvements in AI-based tools.
A good reference might be this thread from last February 2025:
AI Translation Update + New Tool for Church Meetings
The initial post also does a decent job of referencing previous Forum threads on this topic, which may be of interest. Unfortunately, I haven't seen anybody in the Forum post a "success story" from using that tool -- perhaps people have indeed been using it, but there's no posts about that. Also, as it's a year old, there's definitely a lot of new advances and new tools that are out there that wouldn't be captured in that thread.
