Backlight: AI-Powered Legacy System Discovery and Blueprinting

Backlight is Critical Software's autonomous AI engine. It explores your live application — navigating it the way a user would — and captures every module, flow, business rule, and validation it encounters. The result is a structured blueprint of what your system does, ready to drive your next phase. 

It is not documentation. It is the foundation everything else is built from. 

In this solution brief, you'll learn: 

• Why rebuilding a legacy system before understanding it leads to expensive, avoidable mistakes 

• How Backlight moves from setup to a reviewed blueprint in four stages: configure, discover, explore, and review 

• How front-end analysis makes source code unnecessary, working on any running application regardless of stack age or documentation gaps 

• How up to six evidence sources — UI, REST APIs, OpenAPI specs, databases, DDL, and logs — are triangulated into a single blueprint 

• Why a tool-agnostic, human-in-the-loop approach keeps every gap and inference visible instead of silently resolved
