DISCOVER is an Artificial Intelligence (AI)-powered application analysis and understanding solution designed to help IT teams quickly make sense of complex application landscapes—especially legacy environments—and reduce risk during modernization, governance, and maintenance initiatives. With an AI conversational interface, DISCOVER enables users to ask questions in natural language and receive clear, contextual answers about how an application works: key components, dependencies, and the relationships between programs, modules, files, and data structures. This accelerates onboarding, improves collaboration across teams, and helps stakeholders make faster, better-informed decisions. DISCOVER automatically builds an application knowledge base and offers multiple ways to explore it, including visual diagrams, structured documentation, and functional trees. It reveals hidden complexity by highlighting cross-references, coupling points, and critical paths. Teams can use DISCOVER to perform impact analysis, identify obsolete or redundant components, and detect inconsistencies—so changes can be planned and delivered more safely. Built-in indicators (for example complexity metrics, code volume, and comment rate) help prioritize refactoring and modernization work based on effort and risk. For governance and compliance, DISCOVER supports data lineage and end-to-end traceability, helping organizations understand how data flows through the application, where sensitive data may be processed, and what parts of the system are impacted by security or regulatory requirements. This improves audit readiness, strengthens documentation quality, and supports reliable decision-making across the software lifecycle.
