Death of Legacy: Fujitsu AI Writes Code Documentation 97% Faster

Maintaining old corporate software has always been hindered by the lack of up-to-date documentation. On March 30, 2026, Fujitsu brought to market the Application Transform SaaS solution (based on the Kozuchi platform), which solves this problem algorithmically.

Generative AI analyzes the source code of monolithic applications and automatically generates structural diagrams, API descriptions, and design documentation. Fujitsu's internal tests show a reduction in time spent on routine reverse engineering by approximately 97%. For teams planning to migrate old systems to the cloud or rewrite them using modern frameworks, this is a killer feature. The tool moves the refactoring process from the category of an "expensive nightmare" to a predictable engineering pipeline.
