An AI agent is a program based on artificial intelligence that carries out tasks on the user’s behalf on its own. Unlike an ordinary chatbot it does not just reply: it plans the next steps, uses tools and works in several stages, for example gathering data, preparing a report and sending it on. In marketing, agents are starting to take over repetitive tasks: analysing campaigns, preparing content variants or handling enquiries. It is a fast-developing area, so for now it is best treated as operational support under human oversight, not a fully independent replacement. (Compare: Artificial Intelligence, Chatbot)
