Hermes CC is a personal assistant that helps its owner keep track of his own email and calendar. It reads his Gmail to find pending items and deadlines and, only with his explicit approval, labels messages, drafts replies and manages events on his own calendars.
It is a single-person, non-commercial tool. It is not offered to the public, and only the owner's own Google accounts use it. There is nothing to sign up for here.
