Open Knowledge

Open Knowledge gives your AI coding tools — Claude Code, Cursor, Codex, Claude Desktop — first-class access to a living knowledge base built from the markdown in your project.

What you get

• A real editor for your .md files. WYSIWYG by default, source mode when you want it, with backlinks, the wiki-link [[Page]] syntax, frontmatter, asset embeds, and per-document version history.
• AI agents that read and write the right way. Through MCP, agents call read_document, search, write_document, and edit_document instead of native file tools — they get frontmatter, backlinks, and recent edit history every time.
• A live preview as agents work. When an agent writes, the editor opens automatically and the change streams in. You watch your knowledge base evolve in real time.
• No new database. Your knowledge stays as plain markdown files in your project, version-controlled in git like everything else.
