Local laboratory

Six local tools for verifiable decisions.

Everything runs in your browser. Pasted text, results and choices are not sent to the site. These tools do not replace testing from official IP ranges or reading publisher documentation.

Evidence

Claim confidence classifier

Describe the material supporting a recommendation. The result limits the language that can be defended.

Best available source Repeated or independently verified?

Schema.org

JSON-LD structure checker

Checks JSON syntax, @context and @type locally. It does not certify eligibility for a Google rich result.

JSON-LD

Passage

Citable passage checklist

Tests whether a paragraph is self-contained, attributed and bounded. This is an editorial check, not an AI citation prediction.

Passage to review

Measurement

Reproducible prompt panel

Builds a stable set of neutral prompt variants and exports it as JSON. No prompt is sent to an engine.

Topic or entity Audience

Robots.txt

Policy comparator

Compares two robots.txt versions line by line after removing comments and blank lines.

Before After

Robots.txt alone cannot prove effective access: WAF rules, HTTP status, IP verification and rendering must be tested separately.
