CoreStory

AI-powered platform for legacy code modernization

Overview

CoreStory delivers an AI-powered code intelligence platform that helps large enterprises modernize aging legacy software. It reverse engineers complex codebases to produce an Intelligence Model that captures business requirements, system relationships, and developer intent, creating a single source of truth when documentation is missing. The platform can process up to 100,000 lines of code in minutes and translate them into business requirements, user stories, and architectural documentation. It integrates with AI coding assistants to improve work on legacy apps. CoreStory targets Fortune 500 companies and other large organizations to accelerate modernization, reduce risk, and lower the cost and time of projects that historically take 18 months or more. Key use cases include legacy modernization, application maintenance and extension, managing technical debt from AI-generated code, and speeding developer onboarding.
