An AI Assistant is a software program designed to help users perform tasks and answer questions using artificial intelligence. These assistants can understand natural language, allowing users to interact with them through voice or text. They are commonly found in smartphones, smart speakers, and various applications. AI Assistants can manage schedules, provide information, and control smart home devices. Popular examples include Siri, Google Assistant, and Alexa. They continuously learn from user interactions, improving their responses and capabilities over time, making them increasingly useful in daily life.
