What Is an AI Agent? A Plain-English Explanation
An AI agent is software that uses a language model to pursue a goal across several steps, often using tools like search or a calendar.
Agent versus chatbot
A chatbot answers one message at a time. An agent decides what to do next, calls tools, checks results and continues until the task is done or it needs help.
Common examples
Today agents handle narrow, well-defined jobs.
- Researching a topic and compiling sources.
- Triaging an inbox into categories.
- Updating a spreadsheet from new data.
Where agents fail
Errors compound across steps. A small misunderstanding early can send the whole task off course, so keep humans approving anything costly or irreversible.
Start small
Pick a repetitive task with clear rules and a low cost of mistakes.
- Define the goal in one sentence.
- List the tools it may use.
- Require approval for sends and payments.
Key takeaway: Agents are useful for narrow, repeatable tasks with human approval on risky steps.
