inkeep/open-knowledge: Beautiful, AI-native markdown editor and LLM Wiki · GitHub

OpenKnowledge is a beautiful, local-first markdown editor and LLM wiki with integrations for Claude, Codex, and Cursor.

Available as macOS app or Web app/CLI.

Key highlights:

• Full WYSIWYG so that editing markdown files feels like editing a Google Doc or Notion page.
• Collaborative AI-editing with Claude, Codex, and Cursor desktop apps.
• Out-of-the-box MCP, skills, and templates for LLM Wikis, Agent Second brains, and spec-driven development
• No-code Team Sharing powered by GitHub and git under the hood
• Built-in TUI and CLI for terminal users

macOS: download the desktop app — open the DMG, drag Open Knowledge to Applications, and launch it. Latest release.

Linux or an Intel Mac: run the same editor as a local web app via the CLI (Windows isn’t supported yet) (Node.js 24+ required):

npm install -g @inkeep/open-knowledge
cd your-project
ok init          # scaffold the project + wire up Claude Code, Cursor, and Codex
ok start --open  # serve the editor and open it in your browser
