OpenKnowledge turns a folder of markdown files into a workspace where you and an AI agent can write in the same document. The editor feels like a Notion page but saves plain markdown, with a visual mode, a markdown mode, a properties panel for titles and tags, and a file navigator with search and tabs. Ask Claude, Codex, or another harness to draft a recap, and the edit appears beside the chat as you watch. Select any passage and leave a comment, then send all open comments to the agent in one message. A timeline panel lists every change with a before and after diff, so an agent's rewrite is easy to review and undo. Skills Studio covers writing, browsing, and installing agent skills, and it can link one skills folder across Claude, Cursor, Codex, and others. Starter packs set up LLM wikis and second brains, and a graph view shows how wiki links connect pages. Git sync shares a knowledge base with teammates, and rich components like callouts, tabs, and diagrams make specs readable.
