If you're talking to a twin

You've landed on someone's hiy. Here's what that means, in plain terms.

It's an AI, and it says so

Every twin is labelled as an AI version of a real person. It's not them, and it can get things wrong. If something matters — money, health, a commitment — check with the person themselves.

The "Verified" badge

Next to the "AI twin" label you'll often see a small Verified badge. It means hiy has checked that this twin represents the person or thing named on the page — its own creator — before letting it answer you. A twin can only ever be made of yourself, or a product or organisation you own; the obvious case clears automatically, and anything less clear-cut waits for a person before it can go live. The badge is that check, shown where you decide whether to trust what you read.

The check is tied to the name on the page. Rename a twin away from the name that was checked and the badge goes — a clearance granted for one name isn't handed to another by editing a field. The twin carries on answering; it stops claiming hiy confirmed who it says it is.

It answers from their material

The twin was trained on things that person actually made. When it answers with a citation, you can open it and read the passage it used — the whole passage, and where it came from a page on the web, a link straight to it. Anything you see in quotation marks is the creator's own writing: hiy also composes its own summary of their material to answer well, and that summary is never shown to you. When it says it doesn't know, that's honest: their material doesn't cover it, and it isn't going to invent something to fill the space — and it shows you what it searched before saying so: your question, then any rewordings it tried. If the creator keeps their sources private you still see how many ways it looked, just not the wording.

If you ask something it can't answer, the question is passed to the creator. Asking is useful.

What happens to what you type

  • Your conversation is stored and visible to the creator — the whole exchange, not a summary — so they can see what people ask and improve the twin. If you leave contact details, they see that conversation alongside them. Don't share anything you wouldn't put in an email to them. What they can't see is you across visits: hiy keeps no identity between conversations, so two visits are two conversations and nothing joins them up.
  • Refreshing won't lose your place. The conversation stays put in that browser tab. Close the tab and it's gone from your side — so if you're on a shared or borrowed device, the next person can't scroll back through what you asked.
  • Twins ask for contact details by default, and creators can turn it off, it's always optional, and the card can be dismissed without ending the conversation. If you do leave them, they go to that creator so they can reply — not to a marketing list.
  • We don't sell your data, and a creator's content trains only their own twin, never a shared model.

If something's wrong

Every twin page has a Report link. Use it if a twin impersonates someone without permission, or is being used abusively. Twins are only allowed to represent the person who made them, and we review every report.
