hiy docs
A hiy is an AI twin of you. It answers your audience's questions in your voice, shows where each answer came from, and says "I don't know" instead of guessing.
These docs cover building and tuning your twin, sharing it, embedding it on your own site, and the rules we hold everyone to — including ourselves.
