What is an AI Agent?

Published April 20268 min readBy the Fly AI team

Strip away the hype and you're left with something simple: software that takes action on your behalf. Here's how it actually works.

The Short Answer

An AI agent is a piece of software that reads information, makes decisions based on that information, and then does something — sends an email, fills in a form, updates a database, books a meeting. It doesn't just answer questions (that's a chatbot). It acts.

A chatbot answers questions. An AI agent does the work.

Chatbot vs. AI Agent

Most people have used ChatGPT or a customer support chatbot. You type something in, it types something back. That's it. The conversation stays in the chat window.

An AI agent goes further. Here's how they compare:

Needs you to copy-paste dataReads your emails, CRM, and files directly
One-shot responsesMulti-step workflows with follow-up
No memory between sessionsLearns from previous interactions

How It Actually Works

Behind the scenes, an AI agent has three core pieces:

The Brain (LLM)

A large language model like Claude or GPT reads your data, understands context, and decides what to do next.

The Toolbox

Integrations with your existing tools — email, CRM, ERP, databases, file storage — so the agent can act, not just think.

The Loop

The agent checks its own work, handles errors, and follows up automatically. No babysitting required.

Why this matters for your business

Most teams lose hours every day on repetitive tasks that follow clear rules — sorting emails, updating records, writing reports, chasing follow-ups. An AI agent handles these tasks around the clock, without fatigue, without forgetting, and at a fraction of the cost of doing it manually. The question is not whether AI agents will change how you work. It is whether you will be the one deploying them, or competing against someone who already has.
