Platform

WRITER Knowledge GraphPlatform

WRITER's retrieval layer. A specialised LLM reads a customer's own documents, spreadsheets, slides and PDFs and builds a graph of the semantic relationships between them rather than storing vector embeddings, so retrieval can follow multi-hop connections, break a broad question into sub-questions and return specific source citations before WRITER's Palmyra models generate the answer.

WriterPlatform

Enterprise platform for building AI applications and agents on Writer's own models.
