Wise Woman in the Pocket is a framework and marketplace for smartphone-based guides, which contains the synthesis of life-wisdoms from books and similar sources, on one hand, and the presentness, observation capability, and initiative of a good friend, on the other.
The pocket sage is something that gives advice when a person needs to hear it, in an unobtrusive manner, on topics selected by the user.
It is different from usual chat bots as it primarily operates 24/7, based on voice recognition, and shares only occasional short and actionable advice or thoughtful questions in the form of bystander comments. Sometimes it may additionally be capable of participating in a dialogue, but that would not be its primary function.
