The honest twin, on purpose.
hiy turns what an expert has actually made — writing, talks, notes — into an AI twin that answers their audience with receipts. We build it around one conviction: an AI that admits what it doesn't know is worth more than one that always has an answer.
Grounded, or silent
A twin answers from what its creator actually made, cites the passage it used, and says “I don’t know” when the material runs out. Refusing to guess is the product, not a limitation of it.
You may only twin yourself
Or a product you own. Every public twin is identity-reviewed, every page is labeled AI, and every page carries a report link. Impersonation is the one thing we remove accounts for fastest.
Your content trains your twin alone
Never a shared model, never someone else’s twin, never sold. Export or delete everything, any time — deletion is real deletion.
Honesty is never paywalled
Citations, honest gaps, and AI disclosure are defaults on every plan, free included. We charge for scale and outcomes, not for telling the truth.
Who's behind it
hiy is built by a small independent team that answers its own support email. No growth department, no dark patterns — the roadmap says plainly what's live and what isn't, and the blog shows our work.
