OpenKB is an open-source CLI tool that compiles raw documents (PDF, Word, Markdown, HTML, and more) into a structured, interlinked wiki-style knowledge base using LLMs. It is powered by PageIndex's vectorless, reasoning-based retrieval, which uses tree indexing and agentic LLM reasoning instead of embeddings, chunking, or vector databases.

Use cases

• build a persistent knowledge base from my pdf documents
• query long documents without a vector database
• turn a folder of documents into a wiki with cross-references
• chat with my document collection using reasoning-based retrieval
• extract entity pages for people and organizations from documents
• create agent skills from my accumulated knowledge base
• retrieve tables and figures from complex documents
• replace traditional rag with vectorless document retrieval

When to choose

• you want knowledge to compound over time instead of being re-derived on every query
• you work with long, complex documents where chunk-based vector similarity loses context
• you need traceable, explainable retrieval grounded in source documents
• you want native multi-modal understanding of figures, tables, and images
• you prefer a persistent compiled wiki over ephemeral per-query retrieval

When to avoid

• you need low-latency similarity search over massive embedding corpora
• you want a hosted web application rather than a CLI workflow
• your pipeline already depends on a specific vector database stack
• you need real-time indexing of rapidly changing data streams
• you require a mature stable release for production-critical systems
