I believe you’ve been using my AI plugins at some point, Chatbot and AI Topic Summary, since you’ve posted in those Topics, so I will respond for those, but if you want more information, please post in those Topics.
Both of my plugins send usernames and raw Post content (ie the markdown). NB if someone mentions someone’s name in a Post, or an address that will get sent in the markdown, of course, but otherwise Users are only depicted by Usernames.
Other metadata is not sent, e.g. IPs, User Profiles, etc.
You can see the queries being sent in logs if you select the option for verbose logging and divert the logs to Warn (there’s another setting) so they are visible in /logs.
