Worlds is the open-source verifiable context engine designed to manage, query, and prove interoperable knowledge bases at the edge. 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.
