Prove what a document is — and what changed.

In legal and professional work, the provenance of a document is the case. Docurensic compares versions, audits signatures and revision history, and gives you a clear, explainable record of every difference.

What a swapped signature page looks like.

Signature no longer covers the file

The signature seals an earlier revision; content was appended after it was applied, so the final page falls outside the signed byte range — consistent with a signature page swapped in after signing.

§03 / WHY IT WORKS

Why generic checks miss it.

A contract that was edited after signing, an exhibit with a changed date, a scan with a doctored region — these are the disputes that hinge on forensic evidence. Docurensic's compare tool shows word-level differences and font forensics side by side, and every finding is attributed and explainable.

Because findings are evidence for a human decision rather than a black-box score, the output is something you can actually stand behind.

Five layers, one verdict. Every document runs through security, forensics, reasoning, validation, and external lookups — see how the engine works.

§04 / FAQ
Questions

Frequently asked.

Can it compare two versions of a document?

Yes. The compare tool produces a word-level diff with located change boxes, plus font forensics that flags where the same text is set in a different typeface — a common sign of an edit.

Does it audit signatures?

It checks embedded signatures and revision history and surfaces inconsistencies, as evidence for a human reviewer rather than a legal determination.

Is the output defensible?

Every finding is attributed to the layer that caught it and explained in plain language, so you can show what was flagged and why.
