Lettria
PaidGraphRAG and ontology tools for regulated industries
What is Lettria?
Lettria turns unstructured documents into ontology-based knowledge graphs for AI applications. It serves finance, healthcare, legal and engineering teams that need traceable answers, offering a GraphRAG platform and a developer tool called Perseus.
Knowledge Studio is the business-facing platform for document intelligence, with document parsing, ontology enrichment and text-to-graph conversion. Perseus lets technical teams generate ontologies and knowledge graphs from domain data, version them and keep business experts in the review loop.
The pitch is that graph-based retrieval reasons over connected facts where plain vector search falls short, with a claim of over 30 percent better accuracy. Plans are discussed with sales, and a forward-deployed option exists for complex enterprise rollouts.
