LumenIndex is a FastAPI web application deeply optimized from the open-source PageIndex architecture. It keeps the PageIndex idea of reasoning over document structure instead of relying on vector embeddings, then adds a delivery-oriented backend, persistent ChatGPT-style sessions, multi-document retrieval, user isolation, context compaction, Docker deployment, and a liquid-glass web interface. If you are searching for PageIndex web app , pageindex FastAPI , PageIndex RAG , vectorless RAG , or reasoning-based document retrieval , LumenIndex is designed to be a practical, self-hostable implementation for those workflows. Why LumenIndex - Vectorless RAG over document structure : uses outlines, page ranges, section paths, lexical evidence, and agentic tool use instead of requiring embeddings or a vector database. - Built for real users, not a demo : local accounts, HTTP-only sessions, per-user documents, per-user chat history, admin management, and asset isolation. - ChatGPT-style conversation history : one conversation is one persistent history, with selected documents and context preserved across turns. - Automatic context compaction : long ReAct sessions are summarized and archived when approaching the configured context window. - Multi-document retrieval : ask over multiple PDFs, DOC/DOCX files, and Markdown documents in one chat. - St","default_branch":null,"files":null,"tree":[],"storefront":"/r/JMY2003","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/JMY2003/pageindex-lumenindex-agentic-rag/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
