What is Lettria?
Lettria is an AI‑powered document intelligence platform that converts unstructured PDFs and other text formats into structured knowledge graphs, enabling users in regulated sectors such as healthcare, finance, legal, and engineering to retrieve precise, traceable answers from internal documents and external sources.
Its core modules—Document Parsing, Ontology Building, Text to Graph Pipeline, and GraphRAG—automatically extract tables, diagrams, reading order, domain entities, and relationships, then combine graph retrieval with vector search to eliminate hallucinations and improve retrieval‑augmented generation accuracy by up to 30%.
The platform supports API‑driven NLP services, including text mining and classification, that can be integrated into compliance monitoring, regulatory review, financial disclosure analysis, and technical troubleshooting workflows. By grounding responses in explicit source documents and maintaining audit‑ready provenance, Lettria facilitates evidence‑based research, reduces manual cross‑checks, and accelerates the deployment of trusted, enterprise‑scale AI assistants.
