Kathalyst provides AI‑generated documentation that extracts and maps the business logic of legacy mainframe applications, giving teams a clear understanding of how those systems operate. By turning this insight into actionable models, it enables faster, lower‑risk modernization projects such as replatforming or refactoring without costly guesswork or external consultants.

Problem
Legacy mainframe applications often lack up-to-date documentation, making it difficult for organizations to understand the embedded business logic. This knowledge gap forces reliance on expensive consultants and creates high risk when attempting replatforming, refactoring, or rewriting projects.
Solution
Kathalyst applies artificial‑intelligence techniques to automatically generate comprehensive documentation of legacy system behavior and data flows. The platform extracts code, configuration, and runtime information, then visualizes the business rules and dependencies in an interactive format. By delivering clear, machine‑generated artifacts, Kathalyst enables internal teams to assess modernization options with confidence and reduces the need for external expertise. The resulting documentation can be exported as design specifications, migration roadmaps, or API contracts to support cloud‑native redevelopment. This approach shortens project timelines, lowers licensing and operational costs, and mitigates the risk of functional gaps during transformation.
Target Audience
Primary customers are enterprise IT departments and application modernization teams that manage legacy mainframe workloads and need accurate, internal documentation to plan migration, refactor, or rewrite initiatives.
Features
- AI‑driven code analysis that parses COBOL, PL/I, and other mainframe languages to produce structured documentation
- Interactive visual maps of data flows, business rules, and system dependencies
- Exportable artifacts such as functional specifications, data dictionaries, and migration blueprints
- Integration hooks for CI/CD pipelines to feed documentation directly into refactoring or replatforming tools
- Automated change impact analysis that highlights potential regression areas before code modifications
