OpenWriter

Markdown-native writing surface where an AI agent writes and you approve every change.

Webfreeglobal

OpenWriter is a free, open-source, markdown-native writing surface built for AI agents and humans to write together — an agent proposes edits, and the human reviews and approves each change before it's saved. Documents stay as plain markdown files on disk with no database or vendor lock-in, and it works with any MCP-compatible agent. It's aimed at writers and content teams who want the productivity of AI writing agents like Claude Code brought to prose, not just code.
