Free

Open-source, graph-native context and knowledge-graph infrastructure for accountable AI agents in regulated domains.

Graph-Native Ingestion: Ingest enterprise data and extract entities, relationships, and provenance into a Context Graph plus a formal Knowledge Graph.
Polyglot Graph Storage: Native support for both RDF and Labeled Property Graphs so you can pick the model that fits each domain.
W3C Standards & Interoperability: SPARQL, OWL, and related standards keep the graph portable across tooling with zero vendor lock-in.
Deterministic Reasoning: Rule-based and causal reasoning over the graph so agent decisions are reproducible, not black-box.
Decision Provenance: Every decision is traceable back to the ingested evidence and the reasoning steps that produced it.
Ontology & Knowledge Modeling: First-class tools for defining, evolving, and enforcing the domain ontology that governs agent context.
Self-Hostable: Deploy the whole stack inside your own infrastructure — the code is MIT-licensed and open.
Regulated-Domain Ready: Built for high-stakes, governed use cases where auditability and end-to-end traceability are mandatory.

Auditable Agent Decisions: Build agents in finance, healthcare, or public sector where every decision must be traceable to source data.
Enterprise Context Management: Turn scattered enterprise data into a queryable Context Graph the agent uses as its long-term memory.
Causal Analysis: Run causal reasoning over the graph to explain outcomes, not just correlations.
Ontology-Driven Extraction: Enforce a domain ontology so extracted entities and relationships remain consistent across sources.
Regulated Deployment: Self-host in a compliance-bounded environment with zero third-party data egress.
Knowledge Graph Bootstrapping: Ingest documents, databases, and events into a formal KG that agents and BI tools share.
