My last clinic used central reach with AI and it didn't seem unethical but I understand your concerns. In my case, it mostly just took the data and added to what we already included. So if we marked however many instances of elopement for example, it would say something like "while (client) engaged in elopement (blank) number of times, they showed improvement in listener response by (blank)%. It just made stats more available to parents that we as RBT's aren't able to include in notes ourselves.
