A shared canvas where your agent drafts and you approve
What is Plainpaper?
Plainpaper is the shared canvas your AI agent builds marketing campaigns on. Connect Claude, ChatGPT or any MCP client and it writes research, segments, emails and ad creative back as cards on a shared board. Your brand rules bind before it writes, and nothing ships until you approve it. Plainpaper brings no model of its own and never sends an email or publishes a post itself.
