Document intelligence built for regulated industries.
Lettria builds agents designed around complex, high-risk documents. Including multimodal content and advanced reasoning tasks. Built for teams who can't afford hallucinations.
TRUSTED BY LEADING BUSINESS LEADERS AT
Solving the real RAG problem.
Harness graph-based conversational agent for to improve Vanilla RAG’s accuracy by more than 30%.
Built on our suite of 4 modules covering document parsing, ontology building, graph generation and retrieval.
Most RAGs lose structure with tables, diagrams, or multi-column layouts.
Lettria’s graph-based, layout-aware parsing keeps every element intact — preserving relationships and context so complex documents become fully accurate, queryable data sources.
Keyword search can’t handle multi-step, conditional numerical questions.
GraphRAG builds a semantic map of your knowledge, enabling reasoning across documents, applying constraints, and delivering answers that truly support decision-making.
Without structure, agents hallucinate and fail at complex workflows.
Lettria’s dynamic knowledge graph grounds agents in facts, enabling step-by-step reasoning, traceable decisions, and reliable execution in high-stakes environments.
Powered by the Lettria AI Engine™
Save months of engineering effort with an all-in-one AI pipeline. We untangle the complexity of unstructured data—document parsing, vector indexing, knowledge graph linking, and RAG orchestration—so your teams can focus on building advanced, verifiable AI solutions on a single platform.
Doc Parsing
Tame even the wildest PDFs: our API reconstructs reading order, extracts tables and diagrams, so you finally understand your documents.
Ontology Building
Generate precise ontologies in seconds: our research-driven engine auto-structures your knowledge base without tedious manual mapping or guesswork.
