Resistant AI sells an enterprise programme against AI-enabled financial crime across channels. Teams switch to TamperCheck when their actual problem is a backlog of PDF and image submissions, not a cross-channel AI-risk mandate.
Why teams look for a Resistant AI alternative
- You don't need deepfake and voice-fraud coverage - you need document verdicts, and an enterprise programme is more than the problem requires.
- Pricing and access both go through sales; you can't test it on your own documents without booking a demo.
- You want findings tied to a region of the file, not a document-level score with a list of triggered indicators.

What switching gets you
- Test it today - $0.50 per document from your first upload, no demo required.
- Findings tied to the exact field, not a whole-document risk score.
- Live in days, not after standing up an enterprise AI-fraud programme.
When Resistant AI is still the better fit
- Your mandate is genuinely cross-channel - deepfakes, voice cloning, multi-channel GenAI attacks - not only uploaded documents.
- Procurement expects a named AI-fraud platform with dedicated coverage and a roadmap aligned to enterprise controls.
Scoping down from a programme to an API
Most teams evaluating this switch already have a document backlog problem today, and the honest question is whether they need the institution-wide programme Resistant AI sells to solve it. If the mandate really is documents - loan packets, bank PDFs, IDs, invoices - a single endpoint returning field-level findings solves it faster than standing up a cross-channel risk programme.
There's no contract migration to manage on the Resistant AI side if you never signed one - which is often the case, since access is demo-gated. The actual work is just pointing your document pipeline at TamperCheck's API and mapping its findings into whatever review queue you already run.
Resistant AI alternative: common questions
Do I need Resistant AI's full platform, or just document checks?
That depends on your mandate. If your team's job is cross-channel AI fraud strategy across voice, deepfakes and documents, Resistant AI's programme may be the right scope. If the actual backlog is PDF and image submissions, a focused document API answers the same question faster and without the procurement cycle.
Can I try TamperCheck without a sales call?
Yes - pricing is published at $0.50 per document and the API is available from your first upload. Resistant AI's access is demo-gated, so this is one of the more concrete differences in how fast you can get a verdict on your own documents.
Which is better for AI-generated documents specifically?
Both treat generated documents as a first-class threat. TamperCheck's dedicated AI-generation and deepfake pass resolves to the individual field; Resistant AI's institution-wide programme covers synthetic media across more channels than documents alone, if that broader scope is what you need.
