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.

About

Verdent is an AI-powered development platform designed to help developers manage large-scale complexity and deliver production-ready code with efficiency and reliability. It consists of two products, Verdent Deck, a desktop app, and Verdent for VS Code, an integrated extension. Both support running multiple AI agents in parallel, provide DiffLens to explain code diffs by highlighting what changed and why, offer GPT-5-based code review, implement Plan-first Alignment for structured execution, and include a browser tool and verifier subagent to check accuracy. Verdent Deck allows developers to run multiple tasks with oversight in isolated contexts, completing them asynchronously while providing a clear project overview and progress tracking. Verdent for VS Code operates as an AI coding agent that autonomously plans, codes, and verifies tasks within the editor, optimized for engineers who need precision, transparency, and dependable results in production-grade environments.
