Lettria

Lettria is a specialized AI platform designed specifically for regulated industries that need to extract reliable insights from complex documents. It takes messy, unstructured documents like financial reports, legal contracts, medical research papers, and technical manuals, and transforms them into structured, verifiable knowledge. The system handles challenging PDF formats with multi-column layouts, tables, and diagrams, extracting the actual content while preserving reading order and document structure.

What sets Lettria apart is its four-module approach that works together seamlessly. The document parsing module handles the initial extraction, followed by automated ontology building that creates domain-specific knowledge structures. The text-to-graph conversion then transforms content into rich knowledge graphs with entities and relationships, while the GraphRAG module ensures outputs are grounded in source material without hallucinations. This combination provides full traceability—every insight can be traced back to its original source document, which is crucial for compliance and auditing purposes.

This tool is particularly valuable for professionals in healthcare, finance, legal, and engineering sectors who deal with high-stakes documentation. Medical researchers can use it to analyze clinical trials and publications with evidence-backed answers. Legal teams can review contracts and regulations while maintaining control over definitions and interpretations. Financial analysts can extract complex data from disclosures with audit-ready results. Engineering teams can resolve technical issues faster by querying complex documentation with verifiable, step-by-step insights.
