Self-hosted AI document search — connect your scattered docs and ask questions with source citations
Ask questions in natural language across GitHub, Notion, Google Drive, Confluence, S3, and local files. Get cited answers with source links — not hallucinations.
Your data never leaves your network. Run locally with Ollama or connect to OpenAI, Claude, Gemini, Grok. Zero cloud dependency, zero vendor lock-in.
22 built-in plugins — 9 parsers (PDF, DOCX, code, Jupyter), 8 connectors (GitHub, Notion, Drive), 5 AI models. Create your own with one CLI command.
Works as a knowledge base for Claude Code, Cursor, Windsurf, and any MCP-compatible tool. 19 tools for search, indexing, and admin.
Find Korean docs with English queries and vice versa. Hybrid search combines semantic vectors (LanceDB) with keyword matching (SQLite FTS5) via Reciprocal Rank Fusion.
Team mode with OAuth SSO (Google, GitHub), API key auth with RBAC, automatic PII redaction, audit logging, workspace isolation, and per-key rate limiting.
OpenDocuments is an open source RAG (Retrieval-Augmented Generation) tool that connects your scattered organizational documents and lets you search and ask questions using AI — with source citations so you know exactly where the answer came from.
Unlike cloud-only solutions, OpenDocuments runs entirely on your own infrastructure with local LLMs via Ollama. Your data never leaves your network.
