OpenKnowledge is a beautiful, local-first WYSIWYG markdown editor with integrations for Claude, Codex, and other harnesses. For personal notes, team knowledge bases, and LLM wikis.

Key highlights:

• Full true 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. Can be used with any harness/agent via MCP/CLI, like OpenCode.
• Out-of-the-box MCP, skills, and agentic search for LLM Wikis, agent second brains, and knowledge graphs.
• No-code Team sharing and Auto-sync powered by git/GitHub under the hood.
• Embeddable HTML and rich components for writing engineering specs and visualized reports.
• A built-in TUI in the Desktop app and a Web UI for users who prefer terminals.
