Nearly every website now features a chatbot, emulating human interaction to dispense information and address inquiries. While chatbots appear in diverse forms, including physical embodiments and voice-responsive systems, our emphasis is on software-based chatbots proficient in leveraging Natural Language Processing (NLP) to understand text and provide textual responses. This paper employs a systematic review methodology for article selection, listing the most relevant and recent publications related to chatbots, with a particular focus on works cantered on ChatGPT. Furthermore, the selected articles are categorized, and prevailing publication trends are examined.
