The project's README from github.com/inkeep/open-knowledge. As one markdown file: README.md.
OpenKnowledge is a beautiful markdown editor with integrations with Claude, Codex, and other harnesses. For knowledge bases, LLM wikis, specs, and notes. Private, local, and free.

Highlights:
Desktop app — download it from openknowledge.ai/download (or grab an installer from the latest release):
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
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.
Docs for general usage: https://openknowledge.ai/docs.
