About Legacy Code Assistant

Legacy Code Assistant is a platform designed to help engineers, developers, and maintainers of legacy systems understand, document, and generate code for older programming environments.

The platform uses advanced AI to analyze technical documentation, provide insights into legacy systems, and generate code that follows the patterns and idioms of legacy programming languages.

Specialized in Building Automation & Industrial Control

Our enhanced platform now provides extensive support for legacy languages used in Building Automation Systems (BAS), HVAC controls, Programmable Logic Controllers (PLC), and other industrial automation systems. Upload your system documentation and let our AI help you understand, maintain, and extend your critical infrastructure code.
