# The three kinds of twin

One engine, three audiences. They share the same grounding, the same citations
and the same honest "I don't know" — what differs is who they answer and who is
allowed to reach them.

## Your public twin

You, answering your audience, at `hiy.ai/yourname`. Built from what you've
actually made — writing, talks, notes, a CV. It's the one you share, embed, and
put on a business card.

Before it goes live it passes an identity check, because a public twin claims to
be a specific person. A cleared twin carries a Verified badge beside its AI
label.

The badge is tied to the name that was checked. Rename your twin away from that
name and the badge comes off — a check made for one name isn't carried over to
another. Your twin stays live and keeps answering throughout; renaming back
restores the badge on its own, with no second review.

## Support twins

A twin for a product you own. It answers your users from your product's
material, in a neutral voice — it represents the product, not a person.

It's reachable only through a token your own site mints. Anything it can't
answer goes to your inbox with the visitor's email attached, so a stuck user
never dead-ends.

## Team twins

You, answering colleagues from internal material. Invites are just email
addresses, and access begins at first sign-in. Everyone else — search engines
included — gets a 404 rather than a login wall, so the twin's existence isn't
advertised.

A team twin reports what you wrote. It never decides on anyone's behalf, and
there's deliberately no per-person trail.

## Switching between them

Twins live behind the twin switcher in your dashboard. Each keeps its own
knowledge, its own audience and its own rules — adding material to one never
affects another.

You may only twin yourself, or something you own. What enforces that isn't
your address being unique — it's the identity check every public twin passes
before going live, a person reviewing anything the automated check can't
clear, and a report link on every public page that no plan can remove.
