When to choose TamperCheck
- Your problem is specifically documents: loan packets, bank PDFs, IDs, invoices. You want findings tied to regions of the file, not an AI governance platform.
- You want a published price per document you can forecast, not an annual platform fee negotiated at renewal.
- You need checks live in days, not after standing up an enterprise AI-fraud programme across every channel.
- Privacy posture matters to your security team. Ephemeral processing, no document warehouse - easy to explain in a review.
- Signed documents get their certificate checked. A digital signature is only as good as the certificate behind it, so we verify the issuer, whether it sits on a trusted list, and whether the chain holds - as part of the same pass.
When to choose Resistant AI
- You need to address deepfakes, voice cloning, and multi-channel GenAI attacks across the institution. Not just uploaded PDFs.
- You're buying a programme: continuous monitoring, policy, executive reporting for AI-related financial crime risk.
- Procurement expects a named AI-fraud platform with dedicated CSM coverage and roadmaps aligned to enterprise controls.
Documents only vs. full-stack AI fraud
Resistant AI's story is defence against AI-enabled crime at scale - synthetic media, evolving attack patterns, organizational controls. TamperCheck doesn't try to be that umbrella. It tries to be the best possible answer to one question: is this file consistent with an authentic document, and where does it look wrong?
If your risk team's mandate is cross-channel AI fraud strategy, Resistant AI may deserve a seat at the table - even when you still need document checks, those might be one component among many. If your team is working through a backlog of PDFs and images and needs verdicts in production this month, TamperCheck is the tighter fit.
TamperCheck vs Resistant AI: common questions
What is the best Resistant AI alternative for document checks?
TamperCheck.ai, when the mandate is documents rather than a cross-channel AI risk programme. 200+ forensic layers, a dedicated AI-generation pass on every upload, altered field named, 100+ document types from 190+ countries, starting at $0.50 per document with no contract.
Which tool is better for AI-generated document fraud?
Both take generated documents seriously. The practical difference is scope and access. Resistant AI sells an institution-wide programme covering synthetic media across channels. TamperCheck is a single endpoint you can test today, resolving the finding to the specific field on the page.
Can TamperCheck be deployed without a procurement cycle?
Yes. $0.50 per document, published pricing, first top-up matched free in credits. API available from the first document - no demo, no annual commitment, no implementation project. Most teams have a verdict on their own documents within an hour of signing up.
