Phase Change Software is a small company with a big idea:
Automate the Understanding of Code

The solution is simple

We transform existing code into a searchable knowledge base. A developer supplies the search criteria, and in seconds, our platform finds and presents the relevant code in execution order.


The productivity improvement is startling

The developer can abandon the drudgery of rummaging through thousands of lines of irrelevant code and simply query the knowledge base for precise and dependable results. It’s a perfect collaboration, using machine precision to free the developer to focus on work that brings value to the company.

Cutting-edge AI

Our unique AI-reasoning approach digitizes software — converting source code into formal data types. The platform discovers and liberates an application's embedded knowledge by applying cognitive operations such as computational algorithms and machine learning.


Our AI is Precise

Unlike AI modeled on a training set, our AI processes the source code directly, resulting in precision, not probability.

The untapped value of transforming code into a knowledge base

A range of applications


With a searchable knowledge base, various tasks requiring understanding can be supported, including bug fixing, refactoring, modernization, compliance, data lineage research, impact analysis, and other benefits we haven’t even started to explore.

All software languages


We started with COBOL because of enterprises’ many challenges in managing these legacy systems, but the underlying principles can be applied to any programming language.

Exploiting generative AI


The next frontier is combining the precision and explainability of our AI-reasoning engine with the ease of natural language query and description from generative AI to make software accessible and understandable to all roles within the enterprise.

"Indeed, the ratio of time spent reading versus writing is well over 10 to 1. We are constantly reading old code as part of the effort to write new code."
