Open Knowledge

Open Knowledge is an AI-native markdown editor and knowledge base for humans and agents.

OpenKnowledge is an AI-native markdown editor and knowledge base designed for humans and agents. It acts as a canvas for knowledge, offering a Notion-like editor backed by plain markdown files. Users can pin key context, render flowcharts and diagrams, embed videos and HTML, and use templates. The platform is built for agents to co-author and understand knowledge bases, featuring agent skills, native Model Context Protocol for tools like Claude and Cursor, and agentic search with embeddings and hierarchical RAG. It is local-first, open source, and platform-agnostic, with git-backed synchronization to ensure users own their history.
