How does Lettria improve RAG accuracy and what is Perseus?
Lettria's GraphRAG combines graph retrieval with reasoning to deliver transparent, interpretable outputs with reduced hallucinations. Lettria Perseus is the new model that delivers higher precision in graph generation—about 30% more accurate than other LLMs for graph generation, with schema‑valid graphs produced in under 20 milliseconds. The platform also offers a Pilot Program designed to boost RAG accuracy by up to 30%.
What are Lettria's four core modules and what does each do?
- Document Parsing: extracts tables, diagrams, reading order, and multi‑column layouts from complex PDFs to preserve structure.
- Ontology Building: automatically generates clean, domain‑specific ontologies from your documents with no manual mapping.
- Text to Graph: converts unstructured text into a rich knowledge graph with entities, relationships, and constraints.
- GraphRAG: combines graph retrieval with reasoning for transparent, interpretable outputs and reduced hallucinations.
What is Lettria Perseus, and how does it improve graph generation?
Lettria Perseus is Lettria’s model optimized for graph generation. It delivers about 30% higher accuracy than other leading LLMs on graph generation tasks and produces schema‑valid graphs with sub‑20 ms performance. This enables more trustworthy, enterprise‑grade graph‑based AI outputs at scale.
Is there a free trial of Lettria?
Yes. Lettria offers a free no‑code NLP platform trial with 3,000 API credits to test capabilities, no credit card required, full access to the visual interface, personalized success‑team support, and no obligation to continue after the trial.
How can I start a demo or join a pilot program?
You can request a demo to see Lettria in action. There is also a Pilot Program designed to increase RAG accuracy, with messaging indicating up to 30% improvement. If you’re evaluating the platform, starting with a demo and exploring the pilot option is the recommended path.
Which industries and use cases does Lettria serve?
Lettria supports industries including Healthcare, Finance, Legal, and Engineering. It enables practitioners to extract reliable insights from complex documents, build domain‑specific ontologies, and generate verifiable graphs for high‑stakes analysis and decision making.
What evidence demonstrates Lettria's impact for customers?
Lettria highlights customer successes such as:
- Significant ontology enrichment and scalable extraction (e.g., thousands of new classes and hundreds of thousands of articles processed).
- Real‑world impact like faster evidence‑based research in medical teams and improved decision support in enterprise settings.
- Case studies show capabilities across retail, logistics, consulting, energy, and biomedicine, with measurable gains in accuracy and speed.
How does Lettria ensure outputs are trustworthy and explainable?
Lettria emphasizes transparency and traceability. Outputs are grounded in explicit sources and context, with full traceability from data to conclusions. The GraphRAG approach provides interpretable reasoning paths, and Perseus delivers schema‑valid graphs to minimize errors and ensure reliable results.
What outputs can I generate with Lettria (knowledge graphs, ontologies, etc.)?
- Structured ontologies automatically built from your documents.
- Knowledge graphs with entities, relationships, and constraints generated from text.
- Graph‑based insights and explanations grounded in your data sources for verifiable AI outputs.
