AI Domain Data Standard (AIDD) – Authoritative domain identity for AI and search systems

Summary: AIDD is an open, vendor-neutral standard that enables websites to publish authoritative, machine-readable domain identity data for AI systems and search engines. It provides a canonical JSON profile via /.well-known/ with an optional DNS TXT record fallback to improve domain understanding and reduce AI hallucinations.

What it does

AIDD delivers a canonical JSON profile accessible at /.well-known/ and supports a DNS TXT record fallback. It offers plugins for WordPress (pending), Jekyll, Next.js, and CI validation to facilitate implementation.

Who it's for

Developers, site owners, and teams working on AI agents or search engines seeking reliable domain identity data.

Why it matters

It provides AI systems with a reliable source of truth for domain identity, reducing reliance on guessing or scraped metadata.
