ai.txt is a universal standard for describing any resource - websites, projects, folders, services - in plain text. AI agents discover it, learn facts directly, and stop hallucinating. Simple format, optional metadata, works everywhere with cascading discovery. You control your narrative instead of letting AI guess. Easy for non-technical users.
