Jevbox is a self-hostable, permission-aware document library from Extend for uploading, visually browsing, and inspecting parsed documents. It uses Extend for document parsing and stores parsed structures, heading outlines, source passages, and original files; supported viewers include PDF, DOCX, XLSX, PPTX, Markdown, code, JSON, CSV/TSV, images, archives, audio, and video, with a safe download fallback for unknown formats.
Its JEV retrieval system performs permission-filtered hierarchical beam search across categories, documents, and sections, followed by usefulness scoring of source passages. Users can ask questions through the AI SDK or web chat, view inline citations and source previews, attach accessible documents to scope an answer, and connect through REST and MCP APIs. Uploads can be automatically filed by walking existing folders and validating model-proposed branches, while organization permissions are evaluated through SpiceDB.
The repository supports local operation with Node, pnpm, Docker Compose, PostgreSQL, and SpiceDB, and provides Docker, Render, Helm, and AWS/EKS deployment options. It includes organization accounts, invitations, role-based sharing, durable background jobs, queued chat processing, and configurable model providers. Jevbox's original code is licensed under the MIT License; third-party code and assets retain their own licenses.
