About

CoreStory is a code-intelligence platform that uses AI to analyze enterprise codebases and uncover the embedded business logic, architectural structure, and technical dependencies hidden within legacy systems. It breaks down complex applications using recursive decomposition and recomposition to generate a fully queryable intelligence model encompassing business requirements, business rules, workflows, system design, and code-level insights. With real-time interactive access, teams can ask questions of their code, explore entry-points, trace dependencies, and view architecture diagrams to accelerate tasks such as legacy app modernization, application maintenance, AI-generated code governance, and developer onboarding. The platform supports injection via API/MCP into critical engineering systems, enabling visual dashboards like business-process explorer, architecture explorer, and code entry-point explorer.

About

eXplain is a specialized code-analysis and legacy-system evaluation tool from PKS Software GmbH, designed to deeply analyze, map, document, and assess legacy applications, especially on mainframe platforms such as IBM i (AS/400) and IBM Z, so organizations can understand what lives in their software, how it’s structured, and what parts are worth keeping, refactoring or retiring. It imports existing source code into an independent “eXplain server”, no need to install anything on the host system, then uses advanced parsers to examine languages like COBOL, PL/I, Assembler, Natural, RPG, JCL, and others, along with data about databases (Db2, Adabas, IMS), job-schedulers, transaction monitors, and more. eXplain builds a central repository that becomes a knowledge hub; from there, it generates cross-language dependency graphs, data-flow maps, interface analyses, clusterings of related modules, and detailed object-and-resource usage reports.
