Show HN: OpenKnowledge – open source AI-first alternative to Obsidian/Notion

OpenKnowledge is a new open-source tool aiming to provide an AI-enhanced alternative to popular note-taking apps like Obsidian and Notion. It's designed for a seamless "what you see is what you get" markdown editing experience, with direct integrations to various AI services. The creators emphasize that it's completely free, local, and open-source, which is a significant move for those looking for privacy-focused, cost-free alternatives to proprietary software.
