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. FEATURES • Shared Canvas: A central board where your AI agent builds and organizes your marketing campaigns. • Model Agnostic: Lets you plug in your favorite AI like Claude or ChatGPT to do the heavy lifting. • Content Generation: Creates research, audience segments, email drafts, and ad creative for you. • Brand Guardrails: Applies your specific brand rules before anything is written to keep your voice consistent. • Human Approval: Keeps you in control by requiring your final sign-off before anything is published or sent. • Workflow Integration: Works as an interface for any MCP client to help you manage your marketing pipeline.
