Inkeep Releases OpenKnowledge, Open-Source AI-Native Markdown Editor With Claude and Codex Integration

Inkeep unveiled OpenKnowledge on June 27, 2026, a free, open-source markdown editor that enables AI agents to directly read and modify knowledge bases stored as local files, integrating with Claude Code, OpenAI Codex, and Cursor without routing data through cloud servers. The tool combines WYSIWYG editing—designed to feel like working in Google Docs or Notion—with a dual-observer conflict-free replicated data type (CRDT) built on the yjs library, enabling simultaneous editing by humans and AI agents without locking or central coordination. Documents remain as plain markdown backed by git and GitHub, providing built-in version control and auditable change histories, a departure from proprietary platforms like Obsidian or cloud-native services like Notion.
