Check the structure. Inspect the anchors.

Enter an article URL to discover its AIL declaration and check its connection to the content, or a direct JSON URL to validate only the file. Your browser reads it directly from the source and validates it locally. No files are uploaded to our server.

Article or AIL / URL

Article or JSON URL

Use HTTPS. Article HTML and linked JSON must both allow CORS. Each response is limited to 2 MB; redirects are not supported. Article mode follows JSON describedby links and checks document.url plus exact quotations.

Validation report

◇

Ready to validate

Run a structural check to see schema errors, argument-path references and optional quote matches.

Scope of this validator: this tool enforces the keywords used by the published AIL JSON Schema (including types, required fields, enums, patterns, refs and additional properties), plus cross-reference checks. It is not a general-purpose implementation of every JSON Schema feature. Exact-quote presence does not establish that a claim is logically supported or factually true.

What the report means

A pass is the beginning of scrutiny, not the end.

STRUCTURAL

Format correctness

Is the declaration well-formed and compatible with the published record schema?

REFERENTIAL

Internal consistency

Do argument-path IDs point to declared claims, without duplicates or broken references?

TEXTUAL

Anchor presence

When checking an article URL, are claimed exact quotations present in its extracted text? This alone does not prove semantic alignment.
