What an AI agent actually is
An AI agent is a system that can understand a task, use context, and take action inside a workflow. In business terms, that means it can read an email, understand what the request is about, check data in a system, draft a reply, update records, and notify the right person when a decision needs approval.
That is different from a static automation or a simple chatbot. A static automation follows fixed rules only. A chatbot mainly talks. An AI agent does both reasoning and task execution, which makes it useful for real-world business work where every request is similar but not identical.
