Is Resistant AI the same as VerifyPDF?
Not exactly. Resistant AI shares the forensic approach with VerifyPDF, both inspect pixels, metadata and internal structure rather than relying only on OCR. The important differences are scale and go-to-market. Resistant AI is an enterprise platform with a 100M+ document training corpus, an analyst console, multi-language coverage and adjacent transaction monitoring, sold through quote-only sales with a dedicated CSM.
VerifyPDF is a focused forensic fraud API. It runs the same type of checks on financial documents, ships with published prepaid pricing and self-serve API keys, and is designed to plug into an existing stack in days rather than quarters.
When Resistant AI is the right choice
Pick Resistant AI when you are an enterprise buyer and you have the budget, procurement cycle and analyst capacity to make full use of their platform. Their 100M+ document corpus is real and genuinely useful for multi-language coverage, exotic regional formats and hard-to-classify tampering patterns. The analyst console helps investigation teams build a case around flagged documents instead of just getting a score.
Their adjacent transaction monitoring is also a real advantage if fraud operations in your team span documents and payments. For global banks, large insurers and multinational fintechs that already buy enterprise software this way, Resistant AI is purpose-built for that profile.
When VerifyPDF is the right choice
Pick VerifyPDF when you need forensic fraud detection in production quickly and you cannot wait for a full enterprise procurement cycle. Published prepaid pricing, self-serve API keys and an API-only surface area mean you can get your first verifications back in an hour rather than a quarter.
VerifyPDF also fits better when your scope is document fraud alone. If you do not need transaction monitoring, an analyst console or 40+ language coverage, paying for the full Resistant AI platform is overkill. Lenders, insurers, landlords and marketplaces in the US, UK, EU and LATAM use VerifyPDF as a focused forensic layer on top of whatever stack they already have.
Pricing and procurement
Resistant AI does not publish pricing. Their AWS Marketplace listing advertises custom pricing options and requires onboarding with a dedicated customer success manager before production use. Procurement cycles run from weeks to months depending on legal and security reviews.
VerifyPDF publishes prepaid bundle prices on the pricing page. Bundles start at $0.09 per document at the 10,000-document tier, never expire and do not require an annual commitment. Teams that handle fraud for lenders, insurers and landlords usually buy the smallest bundle, validate VerifyPDF against a sample of their own documents, then scale the bundle up once coverage is dialled in. The procurement steps compress to two: pick a bundle and pull an API key.
Migration from Resistant AI
Most teams that add VerifyPDF do not remove Resistant AI on day one. They keep Resistant AI for strategic escalations and use VerifyPDF as the day-to-day forensic API, or vice versa depending on volume shape. If you are fully replacing Resistant AI, plan for the analyst-console gap. Export a quarter of document volume to understand your mix, size a VerifyPDF prepaid bundle against that volume, point your verification endpoint at the VerifyPDF REST API, and rebuild the analyst case-management flow inside whatever tool your operations team already uses. A single integration engineer can typically wire the API up in under a week, the analyst workflow rebuild is usually the slower piece.
