I think the most interesting and “trendy” example of AI is AI chatbot (namely, Chat GPT, although other developpers also try to keep the pace and introduce their conversational chatbots (microsoft Bing, Bard).

AI-powered chatbots can interact with users through text or voice, providing customer service, answering questions, and even making recommendations. Besides, they talk from “I-position” that brings the sense of a conversation with a real interlocuter.
