Gestell provides AI systems and agents specifically trained on legacy system languages to harmonize, modernize, and optimize mainframe operations.

Gestell offers AI systems designed for legacy harmonization, focusing on mainframe modernization, documentation generation, cost optimization, capacity planning, architectural engineering, and security assessments. Their approach involves detailed analysis of z/OS and IBM i systems, mapping architecture, code paths, dependencies, and operational workflows. The AI systems are purpose-built and trained on legacy languages like COBOL, JCL, RPG, and Assembler to accurately analyze complex legacy codebases. They deploy specialized AI agents for tasks such as dependency mapping, business logic extraction, and performance analysis. These agents work autonomously to process millions of lines of code, trace data flows, and build system intelligence. Gestell's team works within client environments, combining AI agents with human orchestration to scale work output and ensure project success. They offer enterprise-grade security with various deployment options, including cloud, bare-metal, or air-gapped, and provide custom fine-tuned AI agents for specific codebases.
