Notion gives you a beautiful writing experience but locks your content inside its own platform; Obsidian keeps your notes as local files but its AI integration mostly comes from community plugins bolted on afterward. OpenKnowledge tries to get the best of both: a real WYSIWYG editor that feels close to Notion, built on top of plain markdown files you fully own, with AI collaboration as a first-class feature rather than an add-on. OpenKnowledge is a free, open-source (GPL v3) AI-native markdown IDE and wiki, built by Inkeep, aimed at engineers and knowledge workers who want a Notion-like writing experience without giving up ownership of their files. Because notes are stored as real markdown on disk and version-controlled via git, tools like Claude, Codex, and Cursor can read and write them directly through MCP — letting an AI assistant search, summarize, and edit your knowledge base the same way it would a codebase. It hit the Hacker News front page and topped Product Hunt on its v2.0 release, drawing 1,400+ signups in its first 24 hours. There are no paid tiers — it's entirely free.
