Semantica

Semantica is an open-source graph-native infrastructure layer for building explainable and auditable AI systems. It ingests fragmented data, extracts meaningful entities and relationships, and transforms them into context and knowledge graphs. Deterministic reasoning, ontology management, provenance tracking, and decision records help explain how conclusions were reached. The platform can complement existing LLMs, vector databases, and agent frameworks rather than replacing them. It supports RDF and labeled-property graphs along with standards-oriented interoperable storage. A browser-based Knowledge Explorer provides graph visualization, temporal inspection, and causal-chain tracing. Semantica is self-hostable and aimed especially at regulated or sensitive environments where decisions must remain traceable and defensible.
