I have developed a conceptual framework for chatbots that includes three primary types:
Informational (e.g. help me find information about X)
Instrumental (e.g. help me figure out if I have X disease, or make an appointment with Y, or resolve my difficulty with Z)
Intrapersonal (e.g. help me feel less lonely, bored, angry, etc.)
The first two categories are replete with developed and performing examples. The last category is lagging.
Is anyone here aware of any chatbot(s) that actually work to reduce a sense of loneliness among users? Even any that show promise? I find articles about people with intentions, but precious little information about successes.
