What generative AI service did Fujitsu launch in March 2026 to analyze source code and create design documents?

Fujitsu Application Transform is the correct answer because it is the generative AI service launched by Fujitsu in March 2026 specifically designed to analyze source code (Review) and automatically generate design documents. This service, powered by Fujitsu Kozuchi, aims to significantly streamline the modernization of legacy systems, which often rely on older programming languages like COBOL.

The need for such a service arises from a common challenge faced by many organizations: maintaining and updating critical software systems that have been in use for decades. These legacy systems often lack comprehensive or up-to-date documentation, making it incredibly difficult and time-consuming for current engineers to understand their intricate workings. Fujitsu Application Transform addresses this by using generative AI and proprietary technology to analyze vast amounts of existing source code and then produce accurate, easy-to-read design documents, even for complex languages.

This innovative AI-powered solution dramatically reduces the manual effort involved in the "discovery phase" of modernization projects, cutting the time needed to generate design documents by approximately 97%. Beyond just documentation, Fujitsu plans to expand the service to include features for rebuilding and rewriting source code, further accelerating the transition of legacy applications to modern cloud environments. By improving comprehensiveness and readability of design documents, Fujitsu Application Transform helps companies gain a clearer understanding of their current system specifications, ultimately supporting more effective modernization and migration strategies.
