Lettria

Turning piles of unstructured documents and data into structured knowledge you can actually query is the job Lettria handles.

Lettria is a GraphRAG platform for enterprise generative AI that builds knowledge graphs from text so retrieval-augmented generation returns more accurate answers.

If your RAG setup keeps producing vague or unverifiable responses, a graph-based approach is the specific fix the company is selling.

The Knowledge Studio is where documents and data get processed.

Answers come back with a way to verify them, and the AI's reasoning is meant to be transparent rather than a black box.

A no-code interface lets non-technical teams work alongside developers and engineers, so a domain expert in legal, finance or healthcare does not have to wait on code to see results.

Lettria sits across several areas: AI API, document extraction, text classification, knowledge graphs, search and chatbots.

Pricing is enterprise only, so expect to talk to the company rather than sign up with a card.

That makes sense for larger organizations more than hobby projects or small experiments.
