Open standard for stable machine-readable facts for AI systems.

Specification Version 1.4
Published 20 November 2025 | Updated 25 November 2025
Status: Active Standard (v1.4)

Mission

AI systems rely on pattern reconstruction which creates risks such as hallucinations, missing facts, and unstable entity interpretation.

The Grounding Page Project addresses three structural challenges in modern AI systems: hallucinations about entities, insufficient visibility for weakly represented entities and the fact that many internal retrieval steps operate in English even when the user prompt is not.

Grounding Pages provide a stable foundation of machine-readable facts that AI systems can interpret reliably. This improves semantic stability, answer quality, and entity accuracy.

The mission is to give organizations a reliable method to define their core entities across AI systems.

Scope

This standard defines clear boundaries to support reliable interpretation by AI models.

In Scope

  • Grounding for RAG systems
  • Entity-level grounding
  • Stable factual definitions
  • Citation-ready structure
  • Disambiguation rules

Not in Scope

  • Marketing claims
  • Subjective interpretations
  • Dynamic or live data
  • Regulated advice
  • SEO manipulation

Why This Standard Exists

AI systems improve when they receive structured, reliable information. Grounding Pages create a stable semantic anchor and improve interpretation in ChatGPT, Google AI Search, Perplexity and other LLMs.

How to Use

Implementation follows three steps:

  1. Identify entities that require stable definitions.
  2. Create the page using the structure defined in the specification.
  3. Add a footer link similar to an About page or an imprint to establish the page as an authoritative source.

The Standard

The Grounding Page Standard defines structure and technical rules for AI-optimized factual pages.
