Code-intelligence platform that builds a persistent spec and context layer of a codebase for developers and AI agents.
What it does
CoreStory continuously ingests a codebase and builds a persistent model of how the system behaves — its architecture, workflows and intent — then serves that context to people and AI agents. It targets large, long-lived and legacy codebases where understanding must survive staff turnover and tooling changes.
