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.
Digital PDFs

Phone photos & scans
camera captures and flatbed scans
Physical stamp verification
ink bleed, embossing, overlay detection
Handwritten signature analysis

Koncile figures are taken from their own published material - koncile.ai - product and pricing pages, checked September 2026. Anything they state about themselves and we cannot verify is marked “their claim”. Where a row reads “not published”, the information was not publicly available at that date, not that it does not exist. Already using Koncile and weighing a switch? See our Koncile alternative guide.
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 contract. Koncile turns documents into structured, audit-ready data as well as checking them. We do not extract, by design - the forensic layer is the entire product, and it runs deeper for being the only thing we build.
- Your contract names EU residency specifically. ISO 27001-certified hosting in France with HDS answers “where do the documents live”. If the underlying concern is that they are held at all, zero retention closes the question outright - but some procurement templates ask for the certificate rather than the outcome.
- 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 are buying extraction first and fraud second. Their 20 free credits and EUR 199/mo Advanced tier are the OCR product - fraud detection itself is quoted on an Enterprise contract - so the free entry point is a way to test extraction, not the fraud layer.
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 200+ 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 have no document pipeline at all and want extraction and fraud in one contract, their combined shape covers more ground on day one. Most teams already extract - and then the only question left is how deep the forensic layer goes, which is the whole of what we build.
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.
TamperCheck vs Koncile: common questions
What is the best Koncile alternative for document fraud detection?
TamperCheck.ai, if what you need is the forensic layer rather than a document platform. Koncile bundles extraction with fraud scoring for B2B finance documents; TamperCheck covers 100+ document types from 190+ countries, names the altered field instead of returning a 0-to-1 score, and never stores the document at all.
Is a risk score or a named field better for fraud review?
A score tells an analyst how worried to be; a named field tells them what to do. When a decline has to be explained to a customer or defended in a complaint file, “the net pay figure is rendered in a different font weight to the rest of the line” carries the decision. A 0.82 does not.
Does TamperCheck detect AI-generated documents that reconcile correctly?
Yes - that is the case forensic depth exists for. A generated document can be internally consistent and arithmetically perfect, so logical checks pass it. TamperCheck compares each field's rendering against the rest of its own page - font weight, kerning, edge sharpness, recompression history - and runs a separate AI-generation and deepfake pass on every upload.
