couplet

macOS markdown editor with live preview that your AI agent can drive through MCP

Desktopfreeglobal

couplet is a macOS markdown editor with live preview and a built-in MCP server, so an AI agent can drive the editor directly and leave comments inside the file that the agent then answers. It's built for people who write markdown alongside an AI agent and want it to edit and comment on the document in place instead of working through a separate chat window.
