Inscribe's core detectors catch a wide range of document fraud out of the box. But every institution has its own policies, risk tolerances, and review processes. The Decision Engine is how you tailor Inscribe to your workflow.
One of the most powerful ways to do that is with Custom Document Insights. They allow you to turn your team's fraud expertise into automated checks that run on every document, every time.

Think of them as rules written in plain language that flag a document when a specific condition is met. They don’t replace any of Inscribe’s existing capabilities. Instead, they add an extra layer of checks tailored to your organization's risk model and policies.
If your analysts are doing a check manually today, there's a good chance it can become something that happens automatically, every time.

Here are some of the most common insights teams are already building.
Document age
A lot of teams have a maximum document age policy. For example, they'll only accept bank statements from the last 90 days. You can build an insight that automatically flags anything outside that window. No more relying on reviewers to catch it themselves.
Metadata that doesn't add up
Bank statements, pay stubs, and utility bills each have characteristic metadata, including the software used to create them, timestamps, and producer fields. When that metadata is missing or inconsistent with what you'd expect, that's often a sign a document has been re-created or tampered with. If your team already knows what to look for, you can turn that knowledge into an automatic check.
Images and screenshots
Documents submitted as images are statistically more prone to fraud. They're harder to analyze and easier to manipulate. You can build an insight that flags every image submission automatically, so reviewers know to take a closer look, without having to remember to check.
Business account submitted where you expected personal, or vice versa
If your workflow requires a personal bank statement and someone submits a business one, that's worth flagging. A quick insight takes care of it.
Stitched bank statements
Multiple statements merged into a single file is a pattern fraud teams see often enough that it's worth catching automatically. An insight can surface these before they move further in your workflow.
Everything lives inside our Decision Engine. You give the insight a name, describe what it detects, set the logic, and choose a severity level (low, medium, or high) depending on how much weight you want it to carry. Inscribe also surfaces suggestions based on what other teams are already using, so you don't have to start from scratch.

Simply ask your team what do we always check manually before approving a document? Whatever comes up is probably a good candidate for your first insight.
Custom Document Insights are often the first thing teams configure because they're the fastest way to automate checks that already exist in your review process. But they're only one part of Decision Engine.
As you learn more about the types of fraud and document behavior that show up in your workflow, there are other ways to tailor Inscribe to your risk model.
Adjust signal severities
Every signal Inscribe surfaces comes with a default severity based on how strongly it correlates with fraud across our customer base. But not every signal carries the same weight for every institution.
If a particular signal consistently turns out to be benign in your document set, you can lower its severity so it doesn't create unnecessary noise. Likewise, if you've found that a certain signal is highly predictive of fraud in your environment, you can elevate it to ensure reviewers treat it as a higher priority.
Fine-tune detector behavior with custom rules
Inscribe's detectors are designed to work across a wide range of document types and use cases. Custom rules let you make them more specific to your workflow.
For example, you might choose to apply a detector only to bank statements, exclude it from pay stubs, or restrict it to PDFs instead of images. This gives you more control over when signals appear without changing the underlying detection logic.
Block software you never want to see
As part of its analysis, Inscribe identifies the software used to create or modify a document. Teams can maintain a custom software blocklist that automatically flags documents created with specific editing tools.
This is particularly useful when your fraud or risk team has identified software that repeatedly appears in suspicious submissions and has no legitimate reason to be present in your document set.
Together, these capabilities help ensure Inscribe reflects how your team evaluates risk, not just how fraud is detected generally.
