A verdict in under 60 seconds
100+ document types across 190+ countries, no template setup required.
$0.50 a document, nothing else
No seat fees, no minimum, no contract. Add $5 and we match it — that's 20 documents free.
Evidence, not just a score
Every verdict cites the signal that produced it: font metrics, metadata, compression, date arithmetic.
Production API from day one
The same engine behind a single API key. Ship a verification step this week, not this quarter.
How your documents are handled
Most verification services retain documents for QA and model training. TamperCheck does not store them at all — which means the shortest possible answer to your security review.
Zero document retention
Documents are analysed in memory and discarded. Nothing is written to disk.
Never used for training
Your documents never enter a training set — ours or anyone else's.
Encrypted in transit
TLS 1.3 throughout, least-privilege access, and audit-ready logging.
Account controls built in
Two-factor authentication, Google SSO, and revocable API keys per environment.

Common questions
- Is TamperCheck free to try?
- Yes. Creating an account is free and requires no credit card. Verification is $0.50 per document, and we match your first $5 top-up with $5 in credits — so your first 20 documents are effectively free.
- What happens to a document after I upload it?
- It is analysed in memory and discarded. TamperCheck does not write submitted documents to disk, does not retain them after the verdict is returned, and never uses them to train models.
- What can TamperCheck check?
- Over 100 document types from 190+ countries — bank statements, payslips, invoices, tax returns, passports and national IDs, degree certificates, employment contracts, insurance claims, utility bills and more. Each is run through 130+ forensic checks.
- Do I need to talk to sales first?
- No. TamperCheck is self-serve: sign up with a work email, add credit, and start verifying. There is no demo gate and no sales call required to use the product or the API.
