One engine,
pointed three ways.
The same grounding, the same citations, the same honest “I don't know” — pointed at three different audiences, with three different rules about who may reach it. How the engine works.
Expert Twin
Answers the world — your audience, at hiy.ai/yourname.
You, answering from what you've actually made — cited on every grounded answer, honest when the material runs out, shareable and embeddable anywhere. It clears an identity check before it goes live and wears the Verified badge to show it, so a visitor knows it's really you.
Who can reach it: Anyone with the link. Indexed, unless you make it unlisted.
Support Agent
Answers your customers — from your docs, in a neutral voice.
It represents the product, never a person. Every answer is grounded in the material you gave it, and what it can't answer becomes a handoff in your Inbox with the visitor's email attached — so a stuck customer never dead-ends.
Who can reach it: Only visitors your own site lets in — the widget works through a token your server mints. There is no public URL to find.
Team Agent
Answers your colleagues — the people you invite, nobody else.
You, answering invited colleagues from internal material — what you wrote, findable and quotable, with the source one tap away. It reports; it never decides on anyone's behalf.
Who can reach it: Invited email addresses only. Everyone else — search engines included — gets a 404, not a login wall.
Grounding and gaps are on every plan, always. Handoffs and team invites come with the Support and Team Agents — part of Founding, and free during your 14-day trial. Resolution analytics, helpdesk integrations and admin controls are on the roadmap.
