Meet the AI Family

AI has a lot of new words: chat, agent, agentic, physical. They sound alike, but they are very different. In about 15 minutes you will be able to tell them apart, and you will have one line to remember.

The players

Four types of AI, one simple difference

Each one does more on its own than the one before it. Here is the short version.

AI Chat

Talks

The advisor. You ask a question, it gives advice. You do the work.

AI Agent

Does

The new hire. Give it a checklist and tools, and it finishes the task.

Agentic AI

Owns the goal

The shift manager. Give it the goal. It plans, assigns and adjusts.

Physical AI

Moves

The machine operator. It sees, decides and moves in the real world.

Think of a factory crew

Most people already know how a crew works. The same roles fit AI.

Notice the pattern in "Your job." As AI does more, your role shifts from doing every step to guiding and checking.

Step by step

Try each one yourself

Each section walks you through one type of AI, step by step. Use the Next and Back buttons. Everything here is a safe practice space. Nothing is sent to an AI tool or to a real order.

AI Chat: the friend who talks things through

You ask, it answers, then it waits for you.

Step 1 · Open a chat tool

Chat tools you may know include Claude, ChatGPT and Gemini. Open one in a new browser tab and sign in.

Check your workplace first. Only use a tool your employer has approved. Never paste passwords, customer data or private records into a tool that has not been approved.

Step 2 · Ask clearly (try the prompt builder)

A good question has four parts: who you are, what you need, the context, and the format you want. Fill in the boxes, and watch the question build.

Background on this example

A machine operator wants to move into logistics. They found a Warehouse Coordinator job post, but they are not sure how their experience matches the list of duties.

Many career changers undersell what they already know, such as tracking inventory, keeping schedules or training coworkers. Chat can help turn that experience into clear resume wording.

Chat only suggests. It does not apply for the job. You choose what to keep.

Watch out: AI can invent experience you do not have, so check that every bullet is true. Keep private details, such as ID numbers or confidential company records, out of the chat.

Try It

  1. Keep the example as it is, or change the boxes above to fit your own job.
  2. Press Build my question and read the question that appears.
  3. Press Copy my question, then paste it into an approved chat tool (such as Claude, ChatGPT or Gemini).
  4. Read the reply and compare each bullet with your real experience. Keep only the bullets that are true.
  5. Ask a follow-up, such as "Make bullet 2 shorter and add a number I can give."
  6. Write down one thing you learned about asking AI clearly. Then try a different format, such as a table, and see how the answer changes.

Step 3 · Send it and read the reply

Paste your question into the chat and press send. Here is an example of what a reply can look like:

You
Which of my skills match this job? Give me 3 resume bullets.
AI Chat
Your inventory experience and your attention to shipping schedules match this role well. Try: "Tracked daily line inventory to prevent shortages." Would you like more bullets?
Chat talks. It only suggests ideas. It does not send anything for you.

Step 4 · Check, then follow up

AI can sound sure and still be wrong. Before you use any answer, check it against what you know is true. Then ask a follow-up to improve it.

Follow-up to try
"Make bullet 2 shorter and add a number if I can give one."

You stay in charge. You choose what to use, and you send the application yourself.

AI Agent: chat that gets hands

You give one clear task, and it uses tools to finish it.

Step 1 · Give the agent one clear task

Imagine a store's support assistant. A customer writes: "My blender arrived broken. Please refund me." The agent can look up orders, check return rules and start refunds.

Your task to the agent
"Look up order #4821, check the return policy, and start a refund if it qualifies."

Step 2 · Watch it work through the steps

Press Start the agent. Each step runs in order, using a tool for each one.

  • ✓Look up order #4821
    Tool: order system
  • ✓Check the return rules
    Tool: policy library. Item is within 30 days and marked damaged.
  • ✓Prepare the refund of $42.00
    Tool: payments. Waiting for your OK because it moves money.
  • ✓Send the customer a confirmation
    Tool: email

Step 3 · Check the result

You asked once, and it did the steps. You still check the result, especially with money or customer information.

  • Did the refund amount match the order?
  • Did the customer get the confirmation?
  • Does the note in the system match what happened?
Agents do. An agent takes actions, not just suggestions. Ask yourself: "Have I ever used a support chat that actually fixed my problem? That was an agent at work."

Agentic AI: give it a goal, not a task

It plans the steps itself, then checks and adjusts. You set the limits.

Step 1 · Set the goal

Think of a shift manager. You do not tell them every move. You give them the goal and the rules.

Goal for the system
"Keep the plant running with no stockouts."

A late delivery is coming. Agentic AI watches inventory and shipments, spots the problem and plans a fix.

Step 2 · Set the limits

Decide what the system may do alone. Tick the rules you want, then continue.

Try unticking a box and see how the plan changes in the next step.

Step 3 · Watch it plan

The plan updates from your limits. Go back to Step 2 and change a box to see the plan change.

    Step 4 · Keep people in charge

    Agentic AI can check its own work and try again. Still, people set the goal, set the limits and approve key steps. Many real products today are only partly agentic.

    Agentic AI owns the goal. It is the most powerful of the four, so keep your limits clear and visible.

    Question to think about: who in your workplace is usually asked to fix a late shipment? That job is what this kind of AI tries to help with.

    Physical AI: AI with a body

    It senses, decides and moves objects in the real world.

    Step 1 · Meet the machine

    Physical AI leaves the screen. It uses cameras and sensors as eyes, AI to decide, and motors to act. You will sort boxes on a practice belt, the way a warehouse robot does.

    • Sense: the sensor sees a box and reads its size
    • Decide: the AI picks the right bin
    • Move: the robot arm carries the box there

    Step 2 · Run the belt, one step at a time

    Press Next action to run the Sense, Decide and Move steps for each box. Watch the sensor label.

    Sensor: ready
    Belt: boxes waiting
    Small boxes
    0 placed
    Medium boxes
    0 placed
    Large boxes
    0 placed

    Box 1 of 3 is waiting on the belt.

    Step 3 · Check the zones

    Look at the three zones on the belt. Did every box land in the zone that matches its size?

    Step 4 · Safety comes first

    A mistake on a screen can be fixed. A mistake in a machine can hurt someone. That is why physical AI has stop buttons, safety zones and trained people nearby.

    Physical AI moves. Workers who understand how these machines work are in high demand, because robots and people work side by side.

    Your turn

    Name that family member

    Read each situation, then pick the family member you think fits. Each answer is explained right away.

    So what for you

    As AI does more, your skills matter more

    These are human skills, not coding skills. Supervisors and operations people already have the instincts.

    1. Ask clearly

    Give context, steps and examples. Good instructions get good results.

    2. Check carefully

    AI can sound sure and still be wrong. You are the quality check.

    3. Set limits

    Decide what AI can do alone and what needs a person's OK.

    Four safety habits for every AI tool

    • Use only tools your employer has approved.
    • Never paste passwords, customer data or private records into a chat.
    • Check anything that involves money, customers or safety before you act on it.
    • Keep a person in charge of the final decision.
