Ghostwriter

Ghostwriter is a Notion Custom Agent that scans X/Twitter for trending AI content, generates post drafts in any voice style, and learns your writing preferences from every edit.

How it works:

• Scan: Pulls real-time posts from accounts you follow via custom MCP server
• Generate: Creates drafts in 6 voice styles (Karpathy, Elon, Paul Graham, Naval, Sam Altman, or your own)
• Learn: Every time you edit a draft, Ghostwriter extracts your preferences and applies them to future drafts
• Post: One-click publish to X

What makes it different:

• Zero hardcoded rules — all settings, voices, and learned preferences live in a Brain database
• Self-evolving — the more you edit, the better it writes
• Real-time signals — not recycled content, fresh takes on what's happening now

Built with:

• Notion Custom Agent (Instructions + Triggers)
• Custom MCP Server (Cloudflare Workers + Twitter GraphQL API)
• Brain DB (settings / voices / learned preferences)
• Signals DB (content pipeline: draft > reviewed > posted)
