Document Authenticity Check

Paid 1 free analysis per IP, then credits or a subscription.

Upload a PDF and read its own structure for integrity signals — incremental-update layers, content appended past the end-of-file marker, cross-reference anomalies, and date or producer inconsistencies. It surfaces signals to investigate, never a verdict that a document is genuine or altered.

🔒 Your file is scanned in memory and never stored — it isn't written to disk, logged, or sent to any third party. The scan runs entirely on our own server with no external service.

A PDF up to 10 MB. Only the file's structure is read — its visible content is never interpreted or stored.
