Perseus builds and maintains the graph by transforming unstructured text into structured knowledge. A graph database (like Neo4j or FalkorDB) stores and queries it. You need both to build a complete GraphRAG system.
Yes. Most Self-serve and Platform customers build their own ontologies using the SDK or our Ontology Builder. Professional services are entirely optional.
Perseus is highly flexible; it can import and extend existing ontologies in OWL, SKOS, or custom formats to ensure your graph generation follows your specific domain rules.
Pricing for the Platform tier is based on workload capacity and committed usage, rather than a simple per-user or per-query model.
We offer Cloud-managed options for Self-serve and Platform users, VPC deployment for Platform users, and On-prem or air-gapped solutions for Enterprise customers.
Yes. Security documentation including our DPA is available on request for Platform tier customers and above.
