Turn technical documentation into operational intelligence.
Engineering teams rely on precise, domain-specific data scattered across reports, specifications, and manuals. Lettria’s solution extracts and connects critical insights across silos, enabling smarter decision-making in design, maintenance, and compliance. Built for reliability in high-stakes technical environments.
Three key principles
Accurate processing
Our NLP experts have developed AI technology that is better able to read and understand information and contextual relationships in your documents.
Transparent and verifiable
Every answer is accompanied by the relevant graphs and snippets that can be easily checked to ensure accuracy and peace of mind.
Ease of use
The Knowledge Studio is designed to be used by anyone in your company, regardless of their technical skills.
Understand technical specs, schematics, and performance documentation
Our parser can handle diagrams, unit tables, and specification sheets common in engineering environments making it easy to extract and organize key technical data for further analysis or compliance.
Graph relationships accurately
The relationships that define how things work are complex, and engineers have to be aware of how a change in one state will affect all of the others around it. That’s why understanding the relationships in your documents in data is the Knowledge Studio’s first job, revealed in the knowledge graphs that properly trace nodes and causal relationships between pieces of information.
Measure twice, cut once
Engineers know the importance of double-checking their assumptions and calculations – no one wants to be on the job site and realize that a critical mistake crept into the planning process. Lettria’s Knowledge Studio never sends back a black-box answer, but instead gives you both the answer to your question and a visual graph together with snippets that let you easily verify its output.

Frequently Asked Questions
Our pilot program has our team of experts and engineers working directly with you to get the technology up and running, from document input all the way through to setting the Lettria platform up within your information system. And once it’s up and running, the platform has been designed to be intuitive and easy to use, no technical skills required. We’re also available to help whenever you need it, from troubleshooting to developing a new application within your business.
Lettria’s GraphRAG technology is able to virtually eliminate hallucinations in many contexts and can consistently best VectorRAG results by up to 30%. You can check out our full benchmarking between the two here.
Every time you query your documents, the Lettria platform shows you not only the answer, but also the snippets and relationships that led it to provide that answer. By having all of this information side by side, you can quickly check to make sure the machine provided the right answer – no leap of faith required.
Yes. The problem most LLMs have with technical data is that from the beginning the information is never properly parsed. Lettria’s expertise in natural language processing gives us a step up when it comes to developing better ways for machines to interpret complex data. We then take things further by combining the speed of vector-based RAG with the accuracy of knowledge graphs and GraphRAG. The result is industry-leading technology that can properly understand and query all kinds of documents, including those featuring lots of numbers, charts, and tables.
