A podcast about fake receipts, autoregressive image models, and just how much of a threat AI-generated documents are.
In this episode of Good Question, we explore the growing risk of AI-generated documents with Ronan Burke, CEO and co-founder of Inscribe, and Martina Pugliese, Senior Research Scientist at Inscribe.
Hosted by Brianna Valleskey, the episode breaks down the technical mechanics of how generative image models create convincing fake documents, as well as what risk teams can do about it.
From synthetic receipts to near-realistic invoices, the group explores what’s real, what’s hype, and what’s coming next in the arms race between generative AI and fraud detection.
Recent updates to ChatGPT’s image generation capabilities have introduced powerful new tools for fraudsters. Using an autoregressive image model (as opposed to diffusion-based approaches), these systems can now generate entire documents from scratch (pixel by pixel) with highly realistic formatting and texture.
Martina and Ronan unpack how these models work, what they’re good at (like restaurant receipts and invoices), and where they still fall short (like IDs and complex bank statements). While today’s fakes are still flawed, they’re improving fast enough to pass through automated workflows without triggering suspicion.
“The assumptions that a photo equals proof are no longer valid. That’s why this new wave of synthetic media is so important to address,” Ronan said.
Despite their visual appeal, AI-generated documents often contain subtle but revealing flaws:
Martina explains how these anomalies leave behind a forensic trail; one that Inscribe’s detectors can catch. She also shares how the team builds synthetic datasets to stress-test detection models and train new classifiers that specifically target AI-generated content.
At Inscribe, AI-generated documents aren’t just a new threat. They’re a new opportunity for innovation in fraud detection.
We recently released our "AI Generated" fraud detector, which flags documents likely generated by AI using digital signatures and pattern recognition.
Additionally, here's how our systems are evolving to meet the moment:
The episode concludes with a forward-looking discussion on where the industry is headed:
Ronan shares why he’s optimistic: Not because the risk isn’t real, but because the tools to address it are evolving just as fast.
“This is a new class of risk, but it’s a solvable one,” he said. “With the right systems, AI-generated fraud can be detected, flagged, and stopped before it causes harm.”
The episode includes a walkthrough of three fake documents generated by Inscribe’s internal team:
Each document was successfully flagged by Inscribe’s internal AI-generated content detectors.
Ronan Burke is the co-founder and CEO of Inscribe. He founded Inscribe with his twin after they experienced the challenges of manual review operations and over-burdened risk teams at national banks and fast-growing fintechs. So they set out to alleviate those challenges by deploying safe, scalable, and reliable AI.
