Teams that need verified application understanding, business logic documentation, and safer modernization planning

About COBOL Colleague

COBOL Colleague transforms legacy COBOL systems into navigable knowledge by using deterministic AI and knowledge graph technology to decode, document, and explain critical business logic with verified understanding, no hallucinations, and no guessing. It maps legacy code into clear Business Functions, giving teams a reliable way to understand what their systems actually do, where business rules live, and how changes may affect the application. Instead of spending months documenting systems manually, COBOL Colleague captures institutional knowledge automatically by slicing code to reveal complete business functions, including every derivation, condition, and dependency that influences each output field. Its proprietary analysis untangles complex COBOL structures such as REDEFINES, CALLS, PERFORMS, and GOTOs, isolating data transformation logic and producing natural language documentation that technical and business stakeholders can share.
