Core Features

Knowledge Compilation

OpenKB uses LLMs to compile documents into summaries, concept pages, entity pages, and cross-links, maintaining synchronization across the knowledge base.

Source: README
Multi-Modality Support

OpenKB can handle various document formats and retrieve information from figures, tables, and images, not just text.

Source: README
Google OKF Ready

The wiki frontmatter follows the Google Open Knowledge Format (OKF) schema, facilitating knowledge sharing.

Source: README
Skill Factory

OpenKB can distill redistributable agent skills from the compiled knowledge base, enabling the creation of digital experts.

Source: README

Architecture

The 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.
