What is agentic AI, in plain English?

An AI agent is an AI you give a goal instead of a question. It makes a plan, uses tools (a web browser, your email, a spreadsheet, your computer) and works through the steps, checking in when it needs you.

Example: instead of asking “what are good hotels in Lisbon?”, you say “find 3 hotels in Lisbon under $150 a night near the river, compare them in a table, and don't book anything.” The agent visits the sites and comes back with the table.

As of Oct 2026 the big assistants all have agent modes: OpenAI now splits ChatGPT into Chat and Work; Anthropic's Claude can use your Mac or Windows PC (beta, Pro and Max plans); Google offers Gemini Agent, with more agent requests on higher plans. See our agent tools roundup.

Stay safe: 8 rules before you let an AI act for you

  1. Keep approvals on. Use settings where the agent asks before it sends, buys, deletes or submits. Google says Gemini Agent asks you to confirm before purchases; Claude asks permission before using a new app.
  2. Never give it your passwords. Don't paste passwords, PINs or one-time codes into a chat. Sign in yourself when asked, or use the official app connections.
  3. Set spending limits. If an agent can shop, use a card with a low limit or a virtual card, and read the cart before you confirm.
  4. Start with read-only jobs. “Find and list” before “book and pay”.
  5. Watch for prompt injection. Web pages and emails can contain hidden instructions that try to trick an agent. OpenAI and Anthropic both warn about this. Treat odd behaviour as a red flag and stop the task.
  6. Give the smallest access needed. Connect one inbox or one folder, not everything.
  7. Check the work. Agents make mistakes; Anthropic says complex tasks sometimes need a second try.
  8. Keep sensitive data out. No medical records, ID numbers or bank details unless you truly trust the tool and its privacy policy.
