lettria
Lettria provides a Graph Context Layer that unifies structured data and unstructured knowledge into ontology-powered knowledge graphs so AI systems can reason, trace and verify answers. The company positions its offering for complex and regulated industries, emphasizing audit-ready, traceable answers and production deployments. Lettria offers two primary paths: Knowledge Studio (GraphRAG) for knowledge and business teams focused on document intelligence and compliance, and Perseus for developers and technical teams to generate ontologies and build production-ready knowledge graphs.
Lettria transforms unstructured data into structured knowledge using AI and GraphRAG.

Ontology Building
Auto-generate production-grade ontologies from your domain in days rather than months; governed and version-controlled domain models.
Text-to-Graph / Document Parsing
Turn documents, tables and exports (e.g., SAP) into clean, queryable knowledge graphs; the Text-to-Graph pipeline is benchmarked for higher extraction accuracy and speed.
Graph Retrieval (GraphRAG)
Graph-based retrieval that provides full provenance on every answer, enabling multi-hop reasoning and audit-ready responses instead of similarity-only vector search.
Perseus (Developer Platform)
Generate ontologies and knowledge graphs quickly, keep business experts in the loop, and build/version graphs for production deployments.
Governance & Traceability
Designed for compliance and traceability: every answer traces back to its source and ontologies are governed and version-controlled.
Pricing
Current pricing details are not available from the vendor source.
Use Cases
Document intelligence for regulated industries
Knowledge Studio (GraphRAG) converts complex documentation into ontology-backed graphs for regulated workflows where traceability and auditability are required.
Generate production-ready ontologies
Perseus helps developers and technical teams create and version ontologies and knowledge graphs faster with business expert involvement.
Biomedical and healthcare knowledge structuring
Used to structure biomedical research and clinical knowledge for safer clinical AI (case studies: WiseCube, AP-HP).
Technical documentation & engineering
Unify manuals, specs and industrial documentation into an ontology-backed knowledge graph for engineering teams (case study: Alfa Laval).
Large product catalog taxonomy
Unify sprawling product catalogs into a consistent, machine-readable taxonomy (case study: Leroy Merlin).
Integrations
Native tables & document sources
Supports tables, layouts and multimodal documents as inputs for Text-to-Graph.
SAP exports
Explicit mention of turning SAP exports into a clean, queryable knowledge graph.
Enterprise data sources (general)
Connects the sources you already have to build unified graphs from structured and unstructured enterprise data.
