Chatbot de service client IA générative

Il s'agit d'une démonstration d'un chatbot de service client utilisant Generative AI via les API Vertex AI PaLM de Google Cloud. L'application exploite également MongoDB Atlas Search pour rechercher des réponses pertinentes dans une base de données MongoDB Atlas. Enfin, l'application peut détecter les clients insatisfaits grâce à l'analyse des sentiments.

  { "question" : " Proof of income " , "Answer" : " This document may become necessary whenever the sum n proposed is very high.
