AI, GenAI and agents, explained with one task

Same job, three kinds of AI. Click through to see what each does and what’s left for you.

The explainer

Example task A customer emails asking whether you can make a gluten-free birthday cake for Saturday.

Spots patterns in data. It labels, ranks or predicts, but it doesn’t write anything new.

What it does: Your email inbox flags the message as a customer inquiry and files it under “Orders”.
Your part: You still read it, check your calendar and write the reply.
Familiar examples: Spam filters, photo search, map routes

Generates new text, images or code from your prompt. It answers once, then waits for you.

What it does: You paste the email into a chat assistant and ask for a friendly reply. It writes a draft in seconds.
Your part: You copy the draft, check Saturday’s orders, fix details and send it.
Familiar examples: Chat assistants, image generators

Takes a goal, plans steps, uses tools you’ve connected (like email or a calendar) and keeps going. Good ones check with you first.

What it does: Your helper sees the new email, checks Saturday’s calendar, reads your gluten-free notes and drafts a reply with a price from your price list.
Your part: You review the draft and press send. It never sends on its own.
Familiar examples: Assistants with tools, routines and memory
