A message providing device includes: a receiver; and a controller. At least first and second operation modes are operations of a software robot program. The program operates on a service exchanging messages between users. In the first mode, a specific service is executed upon reception of a message or a sticker. In the second mode, the specific service is not executed even if the message or the sticker is received. The receiver receives the message or the sticker from the user. When the received message is a first specific message or the received sticker is a first specific sticker, the controller switches the first mode to the second. When the received message is a second specific message different from the first or the received sticker is a second specific sticker which is different from the first, the controller switches the second mode to the first.
