Cathy is the assistant built into Gigs4You (the chat bubble on web, the Cathy tab in the app).
She can answer ("what are my tasks today?", "who hasn't checked in?", "what is my plan?") and act for you ("post a cleaning job for Saturday", "mark this task done"). Before changing anything, moving money or sending messages, she tells you exactly what will happen and waits for your yes.
She can only do what your own account can do. She can also open a support request for you if something needs a person.
