FAQ
Document tampering detection, explained
What we check, what it costs, and what happens to your documents.
What is TamperCheck.ai?
TamperCheck is a built to catch tampered and deepfake documents for compliance teams. You upload a document (bank statement, payslip, invoice, certificate, contract, or any of 100+ supported types), and you get back a clear AUTHENTIC or TAMPERED verdict with every finding explained in plain English. The whole thing takes about a minute.
How does TamperCheck detect document tampering?
We run 130+ independent forensic checks on every document, all at once. We look for edited numbers, font mismatches, metadata anomalies, template inconsistencies, seal and signature issues, and signs of AI-generated or deepfake content. If anything fails, you get a specific explanation of what we found and where.
How much does document fraud detection cost?
Each document costs $0.50 to check (1 to 6 pages counts as 1 check, 7 to 12 pages counts as 2), plus a small reasoning charge for AI analysis. Add your first $5 and we match it with $5 in free credits — $10 to start verifying. No seat fees, no volume tiers, no minimum commitment.
Does TamperCheck store the documents I submit?
No. Documents are processed entirely in memory and discarded immediately after analysis. We never store, archive, or use submitted documents for model training.
What document types does TamperCheck support?
We support 100+ document types including bank statement, payslip, invoice, insurance claim, degree certificate, employment contract, trade license, medical report, and more, across 190+ issuing countries. You can browse the full list on the document types page.
Does TamperCheck detect deepfakes?
Yes. Alongside checks for edited numbers and forged stamps, we run dedicated AI-generation and deepfake detection - catching synthetically created IDs, bank statements, payslips, and other documents that were never genuine to begin with, not just genuine documents that were altered afterward.
