## Overview
Lettria is an AI platform designed for document intelligence and unstructured text structuring in regulated industries. It combines document parsing, ontology building, text-to-graph conversion, and GraphRAG capabilities to extract reliable, traceable insights from complex technical documents. The platform helps organizations in healthcare, finance, legal, and engineering sectors turn textual data into queryable knowledge graphs with full source attribution and reduced hallucinations. A key limitation is that the platform requires initial setup and domain expertise to define ontologies effectively, making implementation somewhat involved for users without prior knowledge graph experience.
## Key Features
- Document Parsing with table and diagram extraction
- Auto-Ontology Building from raw text without manual rebuilds
- Text to Graph conversion for knowledge graph generation
- GraphRAG for transparent reasoning and retrieval
- Fine-tuned proprietary extraction models
- Full source traceability and auditability
- Multi-source data unification (PDFs, databases, APIs)
- Version control for schemas and ontologies
- No-code collaborative framework

## Use Cases
- Evidence-based research in healthcare with full traceability for clinical trials and publications
- Biomedical knowledge extraction at scale for research institutions
- Document analysis for regulated industries requiring audit trails and compliance
- Ontology enrichment and automated classification at scale
- GraphRAG workflows for complex document understanding without hallucinations

## Who It Is For
- Healthcare and pharmaceutical organizations managing clinical data
- Financial institutions processing regulatory documents
- Legal teams handling complex compliance documentation
- Engineering firms extracting insights from technical documents
- Research institutions conducting biomedical knowledge extraction
- Enterprise teams requiring traceable, explainable AI outputs

## Pros
- 30% accuracy improvement through GraphRAG compared to standard LLM approaches
- Full source traceability and auditability prevents hallucinations critical for regulated industries
- Automatic ontology generation eliminates manual mapping burden
- Pre-built domain expertise for healthcare, finance, legal, and engineering verticals

## Cons
- Requires collaborative setup process and domain expertise to define effective ontologies
- Implementation typically takes 12 weeks for production deployment
- Primarily targets regulated industries, which narrows general-purpose applicability

## Pricing Plans
- Pilot Program: $-1/month
