Artificial intelligence has moved beyond simply answering questions and generating text. A new generation of AI systems—known as AI agents—is emerging with the ability to plan tasks, use tools, make decisions, and complete multi-step workflows with less human intervention. From managing emails and analyzing data to writing software and assisting customers, AI agents could significantly change how people work. What Are AI Agents? An AI agent is a software system that can perceive information, reason about a goal, take actions, and adapt based on the results. Traditional AI tools usually respond to a specific instruction. For example, you might ask an AI chatbot to summarize a document, and it provides a summary. An AI agent can go further. You could give an agent a goal such as: "Research three competitors, compare their pricing, summarize their main features, and prepare a report." The agent may then: 1) Understand the objective. 2) Break the task into smaller steps. 3) Searc...
