Choosing a document verification partner is a significant decision. This page helps procurement and operations teams understand how TamperCheck compares to Koncile - on pricing, privacy posture, and what it actually takes to get started. Note that TamperCheck works on digital PDFs and scanned hard copies alike - including physical stamp verification and handwritten signature analysis, not just native digital files.

Phone photos & scans

Physical stamp verification
ink bleed, embossing, overlay detection
Handwritten signature analysis
forgery and substitution checks
Side-by-side
| What matters to your team | TamperCheck.ai | Koncile |
|---|---|---|
| Core focus | Document verification only | Data extraction and fraud detection combined |
| What you get back | AUTHENTIC or TAMPERED plus the specific field that changed | A 0-to-1 risk score per document |
| Detection method | 130+ forensic layers plus arithmetic and cross-field checks | AI consistency, forensic artefacts, and metadata layers |
| Data residency | Zero storage - nothing persisted anywhere | ISO 27001 servers in France (SOC 2, GDPR, HDS) |
| Pricing model | $0.50 per document, published, no subscription | Credit-based subscription with a free tier |
| Coverage | 100+ document types across 190+ countries | B2B finance documents - invoices, statements, payslips, tax |
| Buyer | Lending, insurance, HR, tenant screening, education, KYC | Finance, risk and procurement teams |
When to choose TamperCheck
- You need the field, not a score. A 0-to-1 number still leaves an analyst deciding what to do; naming the altered figure does not.
- Nothing may be stored. EU hosting answers “where” documents live; zero retention removes the question entirely.
- You verify well beyond B2B finance - identity documents, credentials, tenancy and medical records across 190+ issuing countries.
- You already have extraction. If your stack parses documents, you need the forensic layer, not a second IDP platform.
When to choose Koncile
- You need extraction and fraud detection in one tool. Koncile turns documents into structured, audit-ready data as well as checking them. We do not extract - that is a genuine gap if you need both.
- EU data residency is contractual for you. ISO 27001-certified hosting in France with HDS is a stronger answer for some regulated European buyers than ephemeral processing alone.
- Your fraud is semantic rather than visual - wrong tax rates, totals that do not reconcile against business rules, supplier logic - and you want that layer as the primary control.
- You want to start on a free tier before committing any spend.
Two different answers to the same question
Koncile's argument is that AI-generated fakes are pixel-perfect and therefore give nothing away visually, so the tell has to be logical - totals that do not add up, tax rates that are wrong, values that contradict business rules. That is a sound argument and we run the same class of arithmetic and cross-field checks. The difference is that we treat them as part of a 130+ layer forensic stack rather than the headline, because a smoothed pixel-level edit to a single figure can still reconcile perfectly and needs catching another way.
The clearer decision is scope. Koncile is a document platform: extraction plus fraud, aimed at finance, risk and procurement. TamperCheck is deliberately one thing - verification - for teams that already have their document pipeline and need a forensic check inside it. If you are buying your document infrastructure now, their combined shape is likely the better purchase. If you have it already, ours is the smaller surface to add.
On residency, be precise about what you actually need. Koncile offers EU-hosted, certified storage; TamperCheck offers no storage. If your requirement is “documents must remain in the EU”, they answer it directly. If your requirement is “documents must not be retained”, we do.
