Worlds is an open-source context engine designed to manage, query, update, and reason over interoperable knowledge bases at the edge. At its core, Worlds is an indexed knowledge graph. It provides agents with a deterministic context graph that offers complete explainability and source provenance, ensuring continually improving output quality and traceable reasoning.
