AI Agents Explained: How They Differ From Chatbots and Why It Matters

AI agents are a new generation of systems built on large language models that can plan, execute, and review multi-step tasks autonomously, going well beyond simple question-and-answer chatbots. Unlike traditional automation tools that follow fixed rules, AI agents understand context and adapt when conditions change, such as locating information on a redesigned webpage. Their work cycle consists of four phases: perceiving inputs, planning steps, executing actions using external tools, and reviewing results before proceeding. Practical use cases include competitive price monitoring, customer support, content creation, invoice follow-ups, and sales outreach. Despite their advantages in saving time and reducing human error, experts stress that human oversight remains essential for sensitive tasks, and access permissions should be carefully controlled.
