Atomara is a forensic verification service for PDF documents: bank statements, pay stubs, invoices, receipts and income letters. It answers one question: was this file edited or generated after it left the issuer? The engine reads the file itself, not a picture of it: object structure, incremental-update history, generator and font fingerprints, metadata that contradicts itself, and digital signatures, including whether a signature covers the whole document. Over 50 forensic signals produce one verdict with the evidence behind it. When the method cannot tell, the answer is "inconclusive", not a guess. No bank templates by design. A template check breaks on the first issuer it has not seen; Atomara works on any PDF from any issuer, in any language. How it is used: • REST API for platforms that receive documents from their own users: tenant screening, property management, marketplaces, HR onboarding, lending, KYC. One synchronous call, Bearer keys, a 100-check trial on a work email. • Web app for anyone who needs a single document checked today, with signed PDF reports and a visual diff. • A free in-browser PDF metadata checker: the file never leaves your computer. Five markets, five languages, one codebase. Built and operated from Kyiv, Ukraine. Docs: atomara.io/docs/api · Platforms: atomara.io/platforms · Free tool: atomara.io/pdf-metadata-checker
