Validates visual/layout alignment against design standards, compliance rules, or document consistency criteria.
Checks a document against layout expectations — a brand standard, a regulatory format, or a previous version — and reports where it diverges. Comparison rather than extraction, which makes it one of the few solutions here with a deterministic reference to check against.
Regulated document formats where layout itself is prescribed, brand compliance at scale, and version comparison across document revisions.
Where layout is genuinely free. Flagging every deviation from a template nobody agreed to produces noise.
Severity must be graded. A validator that reports a font substitution with the same weight as a missing mandatory disclosure will be ignored within a fortnight.
Reporting semantic-preserving differences as violations, which trains users to dismiss the output wholesale.
A fund manager checking that every published factsheet carries the required risk warnings in the prescribed position before distribution.
