What is Lettria?

Lettria is an AI-powered document intelligence platform that transforms unstructured data into structured knowledge, enabling smarter, context-rich decision-making with full traceability. The platform specializes in processing complex, high-risk documents for regulated industries including healthcare, finance, legal, and life sciences. It combines no-code accessibility with enterprise-grade NLP capabilities, allowing business users and technical teams to work together on text processing projects.

The platform features four core modules: Document Parsing (extracts tables, diagrams, and multi-column layouts from complex PDFs), Ontology Building (automatically generates domain-specific ontologies), Text to Graph (converts text into knowledge graphs with entities and relations), and GraphRAG (combines graph retrieval with reasoning for transparent outputs without hallucinations). Additional features include sentiment analysis (30% more accurate than open-source models), emotion analysis (detects 28 distinct emotions), entity recognition, OCR ingestion, text cleaning, text labeling, table parsing, classification, semantic search, batch annotation, and prompt engineering.

Lettria is ideal for organizations in finance, insurance, healthcare, legal, and life sciences where unstructured or semi-structured documents like contracts, claims, and reports must be processed with structure, clarity, and auditability. The platform includes AutoLettria, a no-code AutoML tool for training custom text classification models without coding expertise. It offers over 50 native connectors (SharePoint, S3), Power Automate support, API-first architecture, and European data hosting with GDPR compliance.
