What is an AI Agent?

An AI agent is an AI system that can take actions, use tools, and work through multiple steps to complete a goal. Unlike a simple chatbot that answers one question at a time, an agent can plan, decide, act, observe results, and repeat until the task is done.

What is an AI Agent?

An AI agent is an AI system that:

1Receives a high-level goal from a human
2Plans how to achieve that goal
3Takes actions (calls tools, searches the web, writes files)
4Observes the results of those actions
5Adjusts its plan based on what it observed
6Repeats until the goal is complete

A simple analogy: you hire a junior assistant. You say 'Research our three top competitors and write a comparison report.' You do not tell them every step. The assistant plans, researches, takes notes, and delivers the report. An AI agent works similarly.

The key difference from a regular chatbot: a chatbot responds once. An agent acts multiple times in a loop until a goal is achieved.

A research agent: given a topic, searches the web, reads articles, extracts key information, and writes a structured summary report
A code review agent: analyzes a codebase, identifies bugs, writes fixes, runs tests, and opens a pull request
A data analysis agent: given a dataset, analyzes it, identifies trends, creates charts, and writes a report
A social media agent: given a content brief, researches the topic, drafts posts for multiple platforms, and schedules them
