OpenKB is an open-source, CLI-based system that compiles raw documents into a structured, interlinked wiki-style knowledge base using LLMs.
Source: Official README and linked documentation View on GitHub →OpenKB is being discussed because its innovative approach to knowledge base creation using LLMs, addressing the need for efficient knowledge accumulation and retrieval without relying on vector databases. Its unique features like multi-modality support and Google OKF compatibility make it differs.
Source: Official README and linked documentationOpenKB uses LLMs to compile documents into summaries, concept pages, entity pages, and cross-links, maintaining synchronization across the knowledge base.
Source: Official README and linked documentationOpenKB can handle various document formats and retrieve information from figures, tables, and images, not just text.
Source: Official README and linked documentationThe wiki frontmatter follows the Google Open Knowledge Format (OKF) schema, facilitating knowledge sharing.
Source: Official README and linked documentationOpenKB can distill redistributable agent skills from the compiled knowledge base, enabling the creation of digital experts.
Source: Official README and linked documentationThe architecture involves a raw document input, which is processed by PageIndex for long documents or directly by LLM for short ones. The output is a structured wiki with summaries, concepts, entities, and explorations. The system uses LiteLLM for LLM support and includes a CLI interface for interaction.

OpenKB compiles material into a reviewable Markdown Wiki and directly provides query, Skill, and deck features. The former fits custom application pipelines; the latter fits maintaining a finished knowledge base.
