Lettria

What is Lettria?

Lettria is an AI-powered document intelligence platform designed for regulated industries. It focuses on transforming unstructured data into structured knowledge, enabling smarter, context-rich decision-making. Lettria's technology is built for teams that require high data quality and output reliability, minimizing hallucinations and ensuring trustworthy AI solutions.

How does Lettria work?

Lettria addresses the challenges of traditional RAG (Retrieval-Augmented Generation) systems by leveraging a graph-based conversational agent. This approach improves accuracy by 30% compared to regular RAG systems. The platform is built on four key modules:

• Document Parsing: Preserves the structure of complex documents, including tables, diagrams, and multi-column layouts, ensuring all elements remain intact.
• Ontology Building: Automatically structures knowledge bases without manual mapping, enabling precise ontology generation in seconds.
• Text-to-Graph Generation: Converts text into actionable graphs using fine-tuned open-source models, outperforming closed-source alternatives in speed and accuracy.
• GraphRAG: Combines graph retrieval and reasoning to provide transparent, traceable answers, boosting performance and trust in question-answering workflows.

Key Features

• Layout-Aware Parsing: Maintains the integrity of complex documents by preserving relationships and context.
• Semantic Mapping: Builds a semantic map of knowledge, enabling reasoning across documents and application of constraints.
• Dynamic Knowledge Graph: Grounds agents in facts, enabling step-by-step reasoning and reliable execution in high-stakes environments.
• Lettria AI Engine™: An all-in-one AI pipeline that simplifies the complexity of unstructured data with document parsing, vector indexing, knowledge graph linking, and RAG orchestration.
• Lettria Perseus: A new model that offers 30% more accuracy than other LLMs on graph generation, delivering schema-valid graphs in under 20 ms.

Technology

Lettria’s technology includes:

• Document Parsing API: Reconstructs reading order and extracts tables and diagrams from complex PDFs.
