A personal agents can be implements in various areas. The previous work has been conducted in website and mobile
in corresponding to information retrieval, mobile computing, and artificial intelligence.There are different methods
and framework are proposed in previous research to obtain and enhance agents performance for better
recommendations. This research aims to present comparison previous research based on personal agent in different
areas for understanding of proposed framework design, architecture and its implementations. Personal agent can be
applied to analyse and assisting in completing task especially for solving one purpose, and multi agents system can
be applied at education, industrial, commercial, governmental, military, and entertainment applications for solving
