Abstract: A facility for automatically managing live interactions is described. In response to receiving a request for live interaction from a user, the facility causes an automatic live interaction to be conducted with the user in which messages are received from the user and sent to the user. The facility periodically uses an up-to-date textual transcript for the automatic live interaction to assess whether the live interaction is one well-suited to a human live interaction. In response to determining that it is, the facility causes a human live interaction to be initiated between the user and a human agent in place of the automatic live interaction, and causes to be presented to the human agent text corresponding to at least some of the messages sent from and to the user during the automatic live interaction.
