OpenKnowledge Cloud
Shared Markdown knowledge bases that people and AI agents edit together.
OpenKnowledge Cloud hosts your team's notes, docs and runbooks as shared Markdown knowledge bases, called brains in the app. You edit them in the browser at app.openknowledge.com or in the desktop app, and AI tools read and write the same brains through the MCP server or the open-knowledge-cloud command. Every change, from a person or an agent, is saved with version history and credited to whoever made it.
The MCP tools and the CLI call a brain a project, so these docs say "project" when they describe a tool argument such as project.
