Download and install OpenKnowledge from GitHub.
Summary
OpenKnowledge is a new markdown editor that offers a true WYSIWYG experience and integrates directly with Claude, Codex, and Cursor.
The MacOS app features a file navigator, a WYSIWYG editor, and a link explorer, while the CLI provides a TUI‑first experience.
The editor supports built‑in micro‑programming capabilities (mcps, skills, and RAG) for AI‑second‑brain scenarios and specification writing.
Its architecture includes a bidirectional pipeline that converts ProseMirror ASTs to markdown losslessly, a dual‑observer CRDT to keep ProseMirror and markdown states in sync, and a git‑backed collaborative experience with undo/redo and version history.
OpenKnowledge is built on open‑source technologies such as Tiptap/ProseMirror, CodeMirror, Yjs, Electron, Orama, remark/rehype/micromark/mdast, and @pierre/trees.
The project is fully open source, available on GitHub, and aims to provide a Google‑Docs‑like experience for teams that need markdown collaboration with AI.
Future plans include plugin extensibility and additional features, and the team welcomes community contributions.
OpenKnowledge is free, local, and OSS, making it an attractive tool for developers and writers who want AI‑powered markdown editing without leaving their local environment.
