Unity uses a support chatbot called UB-1 on its customer support portal to answer common questions from developers and, when needed, escalate issues to a human support representative.

Unity's official support help center page confirms that users can start a chat with a bot named UB-1, which can provide information on common questions. If UB-1 cannot resolve the issue, it can raise a ticket with a human member of the Customer Experience team. The scope, underlying technology, and scale of UB-1 are not publicly detailed in primary sources beyond this basic description.
