Show HN: OpenKnowledge – open source AI-first alternative to Obsidian/Notion(github.com)

tl;dr: OpenKnowledge is a local-first, GPL-3.0 markdown editor and LLM wiki positioned as an open-source alternative to Obsidian and Notion, with WYSIWYG editing and built-in integrations for Claude, Codex, and Cursor via MCP/CLI. It ships as a macOS app or a CLI-launched web app for Linux/Windows/Intel Mac, and uses git/GitHub under the hood for team sharing and sync.
HN Discussion:
  • AI integration is too disjointed; users want LLM living inside the app, not external
  • Lack of local LLM support and limited platform availability undermines the local-first claim
  • ~Promising start but missing key features like plugins, collaboration tools, and comments
  • Name collision concerns with existing Open Knowledge Foundation or Google's Open Knowledge Format
  • Genuine need exists for a Git-based, team-shareable knowledge base with AI integration
