OpenKnowledge：开源、AI 优先的 Obsidian/Notion 替代品

AI 导读

OpenKnowledge 是一款开源、本地优先的 Markdown 编辑器，私密免费，提供完整的所见即所得编辑体验。支持 macOS 桌面应用和 Web UI，内置文件导航、搜索、标签和图谱 wiki 链接查看器。可与 Claude、Codex、Cursor 等桌面应用协同实现 AI 编辑，并通过 MCP/CLI 兼容任意 AI 智能体框架。自带 MCP、技能和智能搜索，支持 LLM Wiki 和知识图谱。团队协作基于 Git/GitHub 实现无代码共享与自动同步。支持嵌入 HTML 及富文本组件。桌面应用内建 TUI，Linux/Windows/Intel Mac 用户可通过 CLI（Node.js 24+）以本地 Web 应用运行。可直接打开任何包含 Markdown/MDX 文件的文件夹。开源协议 GPL-3.0-or-later。

推荐理由

把 Claude、Codex 等 AI 代理直接嵌进知识库编辑器，想法比 Notion AI 更灵活，但这类工具最终拼的是细节打磨和生态，现阶段可以尝鲜但别急着切换主力。

正文

Features

Highlights:

  • Full true WYSIWYG so that editing markdown files feels like editing a Google Doc or Notion page.
  • Desktop app (macOS, Windows, Linux) and web UI with file navigator, search, tabs, graph wiki link viewer, and more.
  • Integrated side-by-side AI-editing with Claude, Codex, OpenCode, Pi and others. Can be used with any harness/agent via MCP/CLI.
  • Out-of-the-box MCP, skills, and agentic search for LLM Wikis, 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.

Install

Desktop app — download it from openknowledge.ai/download (or grab an installer from the latest release):

  • macOS (Apple Silicon): open the DMG and drag OpenKnowledge to Applications.
  • Windows 10+ (x64 / Arm64): run the Setup installer — per-user, no admin prompt.
  • Linux (x64 / arm64): install the deb (Debian/Ubuntu) or rpm (Fedora/RHEL) package.

Web app — on any platform (including Intel Macs and servers), run the same editor as a local web app via the CLI (Node.js 24+ and git required):

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

Usage

Use OpenKnowledge by opening any existing folder on your computer that contains markdown or mdx files. The app can be used with existing codebases, wikis, Obsidian vaults, etc.

Think of it as Notion meets VS Code.

You can use it simply as a rich, WYSIWYG markdown editor to start. For existing files or plain notes/docs.

To get more complex, you can use the starter packs to create LLM Wikis, second brains, or more structured knowledge bases.

Either way, the app will walk you through installing the MCP and skills for agent harnesses detected on your computer. These are designed to help agents with enriched search + authoring of documents.

Git/GitHub based sync and sharing can optionally be enabled.
