OpenKnowledge: Open-Source AI-First Note-Taking and Knowledge Management Tool
Score
47Why selected
The project has gained high traction on Hacker News and aligns with the current trend of AI-powered note-taking tools, but it's still in an early stage, hence a moderately high score.
AI commentary
「As AI tools gain popularity, users need a knowledge management platform that protects data privacy while fully leveraging AI capabilities; OpenKnowledge fills this gap.」
Quick overview
OpenKnowledge is an open-source, AI-first knowledge management tool designed to replace Obsidian and Notion. It features a beautiful AI-native Markdown editor and an LLM Wiki, enabling intelligent note-taking, knowledge retrieval, and collaboration. By integrating AI capabilities, it helps users organize, link, and discover knowledge more efficiently while maintaining full data ownership.
- Open-source alternative: fully open-source with self-hosting capability, ensuring data privacy
- AI-native experience: integrates LLMs for intelligent search, summarization, and content suggestions
- Markdown editor: beautiful and easy-to-use Markdown editing with live preview and bidirectional links
- LLM Wiki: leverages AI to automatically generate knowledge graphs and connections, enhancing knowledge discovery

Features
Highlights:
- Full true WYSIWYG so that editing markdown files feels like editing a Google Doc or Notion page.
- macOS app and web UI with file navigator, search, tabs, graph wiki link viewer, and more.
- 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.
Install
macOS: download the desktop app — open the DMG, drag OpenKnowledge to Applications, and launch it. Latest release.
Linux, Windows, Intel Mac: run the same editor as a local web app via the CLI (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 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 VSCode.
You can also start from scratch with one of the starter packs, which include e.g. a template for an LLM Wiki.
The app will automatically initialize your project with MCP and skill configs for agent harnesses detected on your computer. Git sync and sharing can optionally be enabled.
