A Turnkey Conversion Platform COBOL-to-Python... A Modernization Technology Solution that Preserves the Original COBOL Business Application Logic... no LLMs and no hallucinations
TranspilerAI combines AI-assisted programming with deterministic-transformation and semantics-preserving that delivers traceable, auditable results for mission-critical enterprise systems.
The Scale of the Problem
The Race to Fix Aging Systems Is Heating Up
The race to fix aging computer systems is heating up. Enterprise software modernization has become a major application of the artificial Intelligence market.
Legacy systems remain mission-critical. Banks, insurance companies, Federal, State, and municipal governments, airlines, and other large organizations still rely on software written decades ago, much of it in COBOL.
Many of the COBOL software engineers who originally built these systems are retiring, schools no longer teach COBOL, and today's software developers don't want to learn COBOL. This is creating an urgency to preserve and modernize these applications.
Mainframe modernization is risky, costly, and time-consuming.
Although generative AI is changing modernization, and companies are using tools such as ChatGPT, Claude, and GitHub Copilot to analyze code, generate documentation, and explain business logic to accelerate migration projects, but AI is not enough by itself.
Human expertise is still needed because AI can and does misunderstand legacy code, producing incorrect results. Enterprise modernization requires code validation, preserving system behavior and logic, predictable results, mainframe expertise, and engineering oversight.
Introducing TranspilerAI
Enterprise modernization clients expect modernization projects that deliver faster implementation, lower risk, produce predictable outcomes, and reduced costs.
Introducing TranspilerAI. TranspilerAI is an enterprise AI modernization platform that combines AI-assisted programming with deterministic (meaning given the same input, the process will always produce the same output), and semantics-preserving (meaning preserving the same processing logical behavior), and traceable and auditable results suitable for mission-critical systems.
|Built for the Scale of Enterprise Modernization
Large organizations have millions — even billions — of lines of COBOL that power mission-critical systems. Rewriting these applications manually is expensive, risky, and time consuming. TranspilerAI accelerates modernization by using advanced AI and deterministic translation techniques to transform COBOL into production-ready Python while maintaining the original application's business behavior.
