OUR BIG IDEA
We extract the business functions out of the complexity of code and transform them into useable knowledge for everyone.
We transform existing code into a searchable knowledge base. A user can freely explore the extracted business functions and request views of relevant code. Cognitive complexity is reduced, and understanding is increased for all roles.
Instead of the drudgery of rummaging through thousands of lines of irrelevant code, the developer simply queries the knowledge base for precise and dependable understanding. Business users no longer need to consume expert developers' time to answer their questions. It’s a perfect collaboration, using machine precision to free everyone to focus on work that brings value to the company.
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.
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.
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.
The next frontier is combining the precision and explainability of our deterministic reasoning engine with LLMs to create neuro-symbolic AI. The knowledge that has been encoded and perfected across decades of use in the real world becomes an untapped source for the perceptual power of LLMs.
"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."
