When to choose TamperCheck
- You already have OCR or data extraction and only need to know if the document is fake.
- You require strict data privacy (zero retention) and cannot use a service with human-in-the-loop reviewers.
- You want fast, synchronous results (~1 minute) rather than waiting for a human review queue.
When to choose Ocrolus
- You are a lender who needs perfect data extraction from messy bank statements and tax returns, and you rely on their human reviewers to guarantee accuracy.
- You want to calculate cashflow analytics and income metrics directly from the uploaded documents.
Automated forensics vs. human-in-the-loop extraction
Ocrolus is an extraction engine first and foremost. They use human reviewers to guarantee 99%+ accuracy on the data they pull from financial documents, and they catch fraud as part of that process. TamperCheck is a pure software forensic engine.
If your main problem is 'we need this bank statement transcribed into JSON perfectly,' Ocrolus is built for exactly that - with human reviewers in the loop, and the latency and retention that implies. If your problem is 'we already extract the data, but we keep getting burned by photoshopped PDFs,' TamperCheck gives you a fast, private, $0.50 API to catch the fakes without adding human latency.
TamperCheck vs Ocrolus: common questions
What is the best Ocrolus alternative for fraud detection?
TamperCheck.ai, if fraud rather than extraction is the problem you are solving. Ocrolus is built to transcribe financial documents accurately; TamperCheck is built to prove one was altered, naming the specific field, with no human reviewers in the loop and therefore no review latency or retained copies.
Do I still need extraction if I use TamperCheck?
Most teams already have it, which is exactly why TamperCheck stays narrow. If you extract data today - in-house, through Ocrolus, or through any IDP vendor - TamperCheck adds the forensic layer on the same file without duplicating your pipeline.
Is human review more accurate than automated forensics?
They catch different things. A human reviewer verifies that transcribed numbers match the page; they are not examining recompression history or per-field font rendering, and they cannot see a document that was generated end to end with internally consistent values. That is what a forensic pass and a dedicated AI-generation check are for.
