THE REAL COST OF UNDOCUMENTED LEGACY SYSTEMS
Your Critical Systems Are Running in the Dark
AI Documentation: From Tribal Knowledge to Total Visibility
Knowledge Loss & Expertise GapsMost legacy systems - COBOL, PL/I, Natural, Assembler, RPG—rely on developers who are retiring or unavailable. Up to 60% of core system knowledge lives only in people’s heads, leaving organizations exposed when expertise disappears.
Hidden Risks & Operational Blind SpotsWithout accurate documentation, teams can’t safely modify, audit, or integrate legacy systems. This leads to unexpected outages, regression issues, and compliance failures because no one fully understands how programs, jobs, or data flows connect.
Compliance & Audit PressureRegulated industries require traceability - yet legacy systems rarely have updated documentation. HIPAA, Basel IV, FedNow, GDPR, SOX and NIST frameworks all demand clear, defensible system records that undocumented code cannot provide.
OUR TECHNOLOGY
AI-Generated Documentation, Zero Risk
Turn Your Legacy Systems into Clear, Searchable, Fully Mapped Knowledge
What We Deliver- File & Function Documentation - Readable explanations for programs, paragraphs, functions, modules, and data structures.
- Business Logic Extraction - Maps your core rules, workflows, validations, calculations, and decision trees.
- Dependency Mapping - Reveals systems, jobs, utilities, and modules that connect across the enterprise.
- Data Flow Insights - Shows where data originates, how it moves, and where it is transformed.
- Diagram Generation - Flowcharts, interaction diagrams, and architecture views — auto-generated.
- Cross-Language Support - Documentation across your entire mainframe and midrange ecosystem.

Why This Matters?
Your systems aren’t written in one language — they’re a patchwork of technologies built over decades.
CodeAura becomes the single unified documentation layer across all of them.
Why Documentation Is the Safe Choice?
- No Risk. No Downtime. No Code Changes.
- Because we don’t touch production systems, enterprises adopt CodeAura as a low-risk, high-impact first project.
CodeAura is perfect for Audit preparation, Knowledge transfer, Technical debt reduction, Regulatory readiness, Team onboarding, Pre-modernization discovery and Merger & acquisition system analysis.
