Semantica

Semantica is a governed context and semantic layer for enterprise AI. It sits between data sources and AI agents, turning documents, streams and databases into structured context, business semantics and provenance that an LLM, vector store or agent framework can reason over. The aim is that every fact traces to its source and every decision can be audited. The platform ingests and extracts entities and relations from documents and data, builds a context graph of entities, decisions and temporal facts, and models business meaning with ontologies and controlled vocabularies using OWL, SKOS and SHACL. A reasoning and provenance stage uses Rete and Datalog rules, with W3C PROV O provenance records. It is available through an SDK, CLI, REST API and MCP, and the site lists native integrations with LangChain, CrewAI, Agno, LlamaIndex and AutoGen, plus plugins for Claude Code and Cursor. It is aimed at developers and regulated enterprises that need explainable AI decisions, audit trails and data residency control. Installation is through pip. The pricing page lists four paths. The open source Starter tier is free forever. A Pilot is custom priced and scoped to a use case, for teams validating Semantica on their own data. A Managed Cloud and a Self Hosted Enterprise option are both marked as in development, with custom pricing, and are offered to design partners and early access applicants. No fixed prices are published for the paid options.
