With the latest technological advances, intelligent personal assistants are becoming part of our daily lives. In the future, with improvements in artificial intelligence techniques, it is foreseen that individuals' life management will be greatly assisted by intelligent personal assistants. Today, it seems that intelligent personal assistants have not yet reached their full potential. For more efficient use, more technical developments are needed, especially in terms of natural language processing. In order to that, areas which need improvement must be determined based on which challenges are faced. In order to develop more efficient solutions for problems, an initial fundamental evaluation is necessary. In this work, features of intelligent personal assistants are examined and existing applications are referred to. For a better understanding of what features an intelligent personal assistant must contain, a literature review was completed. In-use features which should be improved in the future, challenges challenges which need to be overcome, areas which could be made more efficient, and how to increase usage are determined.
