About

Our proprietary AI reasoning engine precisely navigates through and analyzes the intricacies of the millions of lines of code within your applications. Developers can instantly pinpoint their desired code. You need to understand every business process, piece of data, or decision point embedded in your code before you can confidently manage, change, or integrate the COBOL applications at the core of the enterprise. Colleague transforms your code into a valuable knowledge base with our logic-based reasoning engine. Unlike generative AI, our technology is precise and explainable. Explore and compare different scenarios by changing conditions in real-time without getting lost.
