What is an AI agent?

An AI agent is a system built on a large language model that can pursue a goal over multiple steps on its own — planning, calling tools and APIs, browsing, running code, and reacting to results — instead of just answering one prompt. Agents range from ready-made assistants to platforms for building your own.

Core features to look for

  • Multi-step planning toward a goal, not single replies
  • Tool and API calling (search, code, browsers, apps)
  • Memory and state across a task or session
  • Autonomy with optional human-approval steps
  • Build-your-own with no-code or an SDK/framework
  • Multi-agent teams that delegate subtasks

Who uses AI agents, and how

01

Task automation

Automate research, data entry, outreach, and repetitive multi-step workflows end to end.

02

Coding agents

Plan, write, and edit across a codebase, run commands, and fix failures autonomously.

03

Build-your-own

Use no-code builders or SDKs to create agents wired to your own tools and data.

04

Customer & ops

Agents that resolve tickets, take actions, and coordinate across business apps.

How does an AI agent work?

An AI agent wraps a language model in a loop: it plans the next step, picks a tool or action, runs it, reads the result, and repeats until the goal is met. Access to tools, APIs, memory, and sometimes other agents is what turns a chat model into something that acts, not just answers.
