Fujitsu has launched a generative AI service that automates the analysis of legacy COBOL code, reducing the time required to generate technical design documentation by approximately 97 percent.

Key Points

• The new service, Fujitsu Application Transform, uses the company's proprietary Kozuchi AI to analyze legacy source code automatically.
• A Knowledge Graph retrieval system improves documentation completeness by 95% and readability by 60% while preventing AI hallucinations.
• The tool eliminates the need for deep programming expertise, allowing teams to understand complex systems without relying on specialized human developers.
• Fujitsu plans to introduce additional features later this year to support the automated rebuilding and maintenance of legacy source code.

Why it Matters

This technology addresses the critical global reliance on COBOL, a 65-year-old programming language that still powers essential banking, insurance, and government transaction systems. By automating the modernization process, Fujitsu provides a scalable solution to the growing shortage of legacy system programmers and helps organizations reduce the risks associated with aging infrastructure.
