How it works
Each layer runs independently. Signals combine into the Risk Score, so several medium findings add up and no single weak one decides.
Reads Content Credentials (C2PA), EXIF, XMP, and IPTC. A manifest that says an image generator made the file is the strongest single signal there is. Its absence proves nothing, because re-saving strips it.
Reads the PDF itself: which programs created and last saved it, revisions added after creation, fonts that appear in one number only, shapes drawn over text, and text that differs from what the page shows.
For photos and scans: regions with a different compression history or noise than the paper around them, and areas copied from one part of the image to another.
Reads the document's fields, then checks them in plain code: line items against the subtotal, subtotal plus tax against the total, running balances, payroll tax rates, dates, card brands, and routing numbers.

No tool is. FraudWorks finds evidence of tampering and shows it; it cannot prove a document is genuine, which is why the clean verdict says no issues found. Every finding comes with its evidence so a person can judge it.
PDF, JPG, PNG, HEIC, and WEBP, up to 20 MB and 10 pages. The live demo takes files up to 10 MB.
Demo uploads are never stored. With accounts, originals are deleted after 30 days by default (7 on Free, 1 to 365 on Business), and every result has a delete button.
Results are fraud risk signals for your own internal review, not consumer reports. Do not use them as the only basis for denying housing, credit, employment, or insurance.
Reading a document's fields uses a language model. Every check that decides a signal, from the math to the PDF structure, runs in plain code, so the same document always gets the same findings.
