Ant Group’s Zoloz unveils RealDoc tool to detect AI-generated documents

Ant Group-owned biometric identity verification and fraud prevention firm Zoloz has presented a new tool designed to verify whether a document is real or AI-generated which it describes as an “AI fraud analyst”.

The product is called Zoloz RealDoc and it goes beyond traditional Optical Character Recognition (OCR), offering AI-powered document extraction, verification and comparison for documents in more than 100 languages, says the Singapore-headquartered company.

Generative AI is being used to create and manipulate documents such as invoices, bank statements, pay slips and other types of proof. The technology has broken the assumption that machine readable texts can be trusted, as AI can create perfectly readable documents, according to Jinwei Yang, director of Engineering at Zoloz.

To solve this, the company’s software performs forensic analysis, including metadata inspection, pixel standard frequency analysis, cryptographic and signature verification, document history tracing, timestamp consistency and more.

“These are layers traditional OCR can never touch,” Yang said during an online presentation in November. In the Gen-AI era, a document may look perfectly real, yet inconsistencies hide in pixel domains, compression patterns, metadata and the file structures. Verification makes these invisible signals visible.”

The product was first presented at Alibaba Cloud’s Apsara Conference 2025 in Hangzhou, China in September. Zoloz works under Ant Digital Technologies which is part of Ant Group, an affiliate company of the Chinese conglomerate Alibaba Group.

The company says that the tool was created to assist human analysts and save time: Know Your Customer (KYC), corporate onboarding, Know Your Business (KYB) registrations, licenses, shareholder documents and address proofs need to be processed quickly and accurately. While a skilled human analyst may spend 10 minutes on average reviewing a single document, Zoloz claims that RealDoc can do the same in just 72 seconds.

The system extracts and structures data from complex documents, including handwritten text, tables and watermarks. It can also verify document authenticity by comparing files across different formats and languages, checking them against official sources.

Aside from document analysis, Zoloz also provides identity verification and liveness detection for financial and other services. In 2024, it launched a deepfake detection product Zoloz Deeper while earlier this year, it presented Agentar, a platform for developing smart applications such as AI agents geared towards financial institutions

One of the company’s latest deals was with data and analytics platform Credolab.
