X-Modernize AI
A generative-AI modernization tool from Fresche Solutions, reported by IT Jungle on November 10, 2025, that converts legacy RPG, COBOL, and Synon applications into Java by having AI agents generate code from extracted business rules rather than translating source line by line.
X-Modernize AI is a modernization product from Fresche Solutions, a longtime IBM i application modernization vendor, that IT Jungle reported on November 10, 2025. It converts legacy RPG III, RPG IV, and Synon (a 1990s 4GL) applications, as well as COBOL, into Java 17 code that runs on any JVM. Rather than translating RPG statements directly, the tool builds on Fresche's existing X-Analysis code-analysis product to extract business rules from the whole application, then uses AI agents backed by large language models, including Anthropic's Claude, to generate the Java from those rules. Fresche says it draws on multiple LLM vendors so customers can choose one that fits their data-privacy requirements. It also converts DDS database definitions to DDL for Db2 for i, Postgres, Oracle, and MySQL, and turns green-screen interfaces into JavaScript or React front ends. Fresche builds in automatic test-case generation and human review checkpoints intended to catch AI hallucinations before code ships.
