We built an open source UI kit for document RAG/agents

Extend has released an open-source UI kit designed for document retrieval-augmented generation (RAG) and agent applications, featuring 15 customizable components for handling PDF, DOCX, and XLSX formats, including capabilities for bounding box citations and e-signatures. This toolkit addresses the complexities of building scalable document viewers, having been refined through real-world usage at Extend, where it processes millions of pages daily. It provides a valuable resource for developers building document processing agents and user-facing document intake systems, with the potential for continued improvement through community contributions.
