Utopia

Utopia is an open-source enterprise world model designed to turn evolving organizational knowledge into a governed decision layer. It combines a bitemporal knowledge graph, editable ontology, retrieval, reasoning, and audit history in one self-hosted application. The system ingests documents and synchronized sources, then extracts entities and facts with provenance and validity intervals. Corrections preserve earlier versions instead of overwriting them. Hybrid search and chat work across documents and mounted databases through OpenAI-compatible models. Temporal Datalog rules derive new facts, while conflict detection and review queues surface contradictions or uncertain merges. Role-based permissions and a decision ledger make changes traceable for enterprise use.
