What is an AI agent?

An AI agent is AI that works toward a goal on its own. It plans steps, uses tools such as a browser or your apps, checks results, and keeps going until the job is done or it needs you.

Chatbot: Answers your message
Automation: Runs the same fixed steps
Agent: Decides its own steps to reach your goal

This guide is about using agents. To build one, see our guide How to Build Your First AI Agent.

Personal agents

Claude Duet: Anthropic’s proactive agent with briefs and alerts, in research preview from October 2026
Claude Cowork: Multi-step tasks with your files and apps
Meta Muse: Meta’s personal agent for errands, planning, and small business
OpenAI Dots: OpenAI’s personal agent
Grok Bot: xAI’s AI teammates with skills and routines
Gemini tasks mode: Gemini keeps working on tasks while you are away

Work and coding agents

Copilot Cowork: Microsoft’s agent across Microsoft 365
Claude Code and OpenAI Codex: Coding agents that build and fix software
Zapier Agents and n8n: Agents connected to thousands of apps

Availability, plans, and countries vary, and these products change quickly.

Good first tasks

Research a topic and write a sourced brief
Triage your inbox and draft replies
Prepare for tomorrow’s meetings
Compare products or vendors
Fix a small bug in a codebase

Give clear goals

What done looks like
What it may use
What it must not do
When it must ask you
How to report back

Compare three accounting tools for a five-person business on price, features, and reviews. Use only official sites and reputable reviews. Do not sign up for anything. Give me a table and a recommendation.

Access and approvals

Connect only the apps a task needs
Keep approvals on for sending, paying, deleting, and publishing
Never share passwords or one-time codes in chat
Watch the agent work when it is new

Costs

Agents use far more AI usage than chat, because they loop and use tools. Watch your plan’s limits and start with small tasks.

Risks to know

Agents can misread pages and make mistakes confidently
Web pages and emails can hide instructions that try to trick agents
Some sites block AI agents
Mistakes can repeat quickly at scale

A checklist before trusting an agent

It did the task correctly ten times in a row
You understand every permission it has
Risky actions need your approval
You can see a log of what it did
You can switch it off quickly

The golden rule

Do not hand an agent your whole life. Give it one clear job, limited access, and keep the final yes for yourself.

Give one agent a low-risk research task this week and check every source it used.
