The invention discloses a chat robot development method for performing a narrative therapy for user personality, which comprises the following steps of: S001, selecting a proper data set, and performing deep learning end-to-end model training on the basis of a large number of dialogue logs, and S002, creating the data set, generating word vectors, compiling an end-to-end model, and inputting data into model training to obtain a chat robot model; continuously iterating and optimizing model parameters; and S003, the trained model can make answers to questions consulted by the user based on different personalities. According to the AI chat robot, the problem of user consultation is solved through a narrative therapy method, a psychological method is combined with artificial intelligence, and the AI chat robot capable of doing the narrative therapy is created.
