The stakes
One in five forged documents clears manual review
Your reviewers are good, but a convincing fake now takes minutes to make and seconds to send. Every document you accept on trust is a decision someone else made for you.
A forged payslip becomes a loan you shouldn't have written, on a book you have to defend.
Reviewing a document by hand costs about 15 minutes of someone's time. Checking it properly costs 50 cents.

Net pay should read $3,180. Nothing on the page looks wrong to the eye.
What you get back
Net pay was edited upward by $3,300.
- The altered field is named: net pay.
- Gross pay minus deductions comes to $3,180, so the payslip contradicts itself.
- Everything else on the page checks out, so this is a genuine payslip that was edited.

Manual review figures use the same assumptions as the calculator above: 15 minutes of analyst time per document, and the industry estimate that roughly one in five fraudulent documents passes visual inspection.

AI-generated documents
Catching AI-generated documents that were never real
Editing a genuine payslip is the old way. Today a model will produce a whole one: correct employer, plausible numbers, clean layout, no original to compare against. Checks built to spot edits find nothing wrong, because nothing was edited.
We look for what generated documents cannot fake: the physical traces of a real scan, the quirks of real issuer templates, and the statistical fingerprints image models leave behind. Every upload is checked for synthetic origin alongside every tampering check.
How we detect AI-generated documentsSynthetic origin detection
Image models leave statistical fingerprints. We test every upload for them, whatever the document type.
How it fits

Drop a document in the dashboard and you have your answer. No implementation project, no per-document-type setup, no onboarding call.

FAQ
Document tampering detection, explained
What we check, what it costs, and what happens to your documents.
What is TamperCheck.ai?
TamperCheck.ai checks documents for tampering and AI-generated fakes. Upload a document - a bank statement, payslip, invoice, certificate, contract, or any of 100+ supported types - and you'll get back a clear AUTHENTIC or TAMPERED result, with every issue explained in plain English. It takes about a minute.
How does TamperCheck detect document tampering?
TamperCheck runs 200+ automated checks on every document at once. It looks for edited numbers, mismatched fonts, unusual metadata, inconsistent templates, altered seals and signatures, and signs of AI-generated content. If something looks wrong, you get a plain-English explanation of what it found and exactly where.
How much does document fraud detection cost?
Checking a document costs $0.50 (a 7-12 page document counts as two checks), plus a small charge for the AI reasoning involved. Your first top-up is matched with free credits, doubling what you start with to spend. No seat fees, no volume tiers, no minimum commitment.
Does TamperCheck store the documents I submit?
No. TamperCheck processes each document in memory and discards it immediately after the check. Documents are never stored, archived, or used to train our models.
What document types does TamperCheck support?
TamperCheck supports 100+ document types, including bank statement, payslip, invoice, insurance claim, degree certificate, employment contract, trade license, medical report, and more, issued from 190+ countries. See the full list on our document types page.
Does TamperCheck detect deepfakes?
Yes. Alongside checks for edited numbers and forged stamps, TamperCheck runs dedicated checks for AI-generated and deepfake documents. That catches fully fabricated IDs, bank statements, and payslips - documents that were never real to begin with - not just genuine documents that were altered.
Is TamperCheck better than other document verification tools?
Absolutely.
