Summary

OpenKnowledge is an open-source, local-first markdown editor and LLM wiki that provides a WYSIWYG editing experience similar to Notion or Obsidian. It integrates with Claude, Codex, and Cursor for collaborative AI editing, supports MCP/CLI for agent orchestration, and uses git/GitHub under the hood for team sharing and auto-sync. Available as a macOS app or CLI/web app (Node.js 24+), it targets developers building agent second brains and spec-driven development workflows.
