hiy.ai

hiy.ai builds AI agents that answer only from material you give them: pasted text, pages by URL, PDFs and documents, YouTube transcripts, and whole blogs imported in bulk. A grounded answer shows the passage it came from. When the material runs out, the agent says so instead of guessing and offers to pass the question to a person. One account covers three agents on the same engine: a Support Agent that answers customers on your own site, an Expert Twin that answers your audience from a public page at hiy.ai/yourname, and a Team Agent that only invited colleagues can reach. The Free plan covers the Expert Twin; the Support and Team Agents come with the paid Founding Creator plan. Every surface is labelled as AI.
