Relationships across systems, not just documents
Who each tool is for
Curiosity
For industrial teams that need structured context and on-premises control. Knowledge lives in engineering systems, structured records and regulated environments, and the answers have to reason over how those things connect.

Stardog
Stardog is a semantic knowledge graph platform built on an RDF triple store with full OWL 2 reasoning and data virtualisation. It supports SPARQL queries and fine grained access control, and it suits regulated and compliance heavy use cases. It is a platform that teams model and build on.
Stardog gives you a powerful semantic graph and reasoning engine, and it takes ontology expertise to model and run. Curiosity gives you a finished context layer with the AI layer included, on your own infrastructure.
A finished product, not a toolkit
Stardog needs ontology modelling, pipelines and an interface built around it. Curiosity ships connectors, search, the graph, security, UI and APIs together.
Less specialist effort
Semantic platforms rely on scarce OWL and RDF skills. Curiosity models your data and connects the language model you choose without that overhead.
Connected and in production
Stardog is the engine. Curiosity connects your systems and reaches production as one system on your infrastructure.
