An AI Assistant is a software application powered by artificial intelligence designed to help users by answering questions, providing recommendations, or performing tasks. These assistants use natural language processing to understand and respond to user input, making interactions more intuitive. Common examples include virtual assistants on smartphones, chatbots on websites, and productivity tools that automate routine actions. AI Assistants can enhance efficiency, improve access to information, and support decision-making, while raising important considerations about privacy and data security in digital environments.
