Understand the project
Practical overview
When it fits
Use Utopia when a knowledge system needs more than semantic search: its documented scope brings together graph traversal, ontology support, time-aware records, citations and agent access in a self-hosted deployment.
Who it is for
- Teams building self-hosted enterprise knowledge bases
- Developers implementing GraphRAG and ontology-backed LLM applications
- Organizations needing time-aware records and knowledge history
- Teams integrating agents through MCP or OpenAI-compatible model endpoints
Documented uses
- Build an enterprise knowledge base with graph-based retrieval
- Ingest documents and synchronize selected external sources
- Search and chat across documents using full-text and vector retrieval
- Preserve changing knowledge and inspect facts or changes over time
- Provide agents with read-only knowledge and database tools
