AI Agents in Plain English: What They Are and What They Are Not

A chatbot answers. An AI agent acts. It takes a goal, breaks it into steps, uses tools (search, spreadsheets, code, APIs) and keeps going until the job is done — or until it needs you.

The anatomy of an agent

• Model: the reasoning engine.
• Tools: what it can actually do (browse, send, calculate, write code).
• Memory: what it remembers across steps.
• Guardrails: what it is not allowed to do without asking.

Where agents work today

Research, drafting, data cleanup, support triage, lead qualification and coding. They are strongest when the task is clear, repeatable and checkable.

Where they struggle

Ambiguous goals, high-stakes decisions and anything where a silent mistake is costly. Keep a human in the loop for approvals, money and anything public.
