What is Lettria?

Lettria is an AI-powered document intelligence platform designed for regulated industries such as healthcare, finance, legal, and engineering. It transforms unstructured data from complex documents into structured knowledge graphs, enabling accurate, traceable, and explainable AI outputs. The platform includes modules for document parsing, ontology building, text-to-graph conversion, and GraphRAG.

How to use Lettria?

To use Lettria, start by requesting a demo or pilot program. The typical engagement involves a scoping call, then a pilot phase where you connect your data sources (PDFs, databases, APIs), define your ontology, and build a knowledge graph. Lettria's no-code studio allows you to upload documents, generate ontologies, and deploy AI models with expert support. For production, you can scale to enterprise deployment with custom integrations and compliance features.
